Due to an overwhelming response to <strong>Insulate</strong><br />

<strong>Magazine</strong> over the past eleven issues, Jamie and<br />

I took the decision that we should go to print.<br />

We did not take this decision lightly, our commitment to<br />

delivering media to our readers in the most direct way<br />

though the best mediums still remains, the request was<br />

consistent – subscribers wanted copies for their<br />

reception areas, canteens and boardrooms – why would<br />

we not!<br />

So here is <strong>Issue</strong> <strong>11</strong>, another great edition packed with the latest<br />

industry news and comment. The BBA discuss the whole home<br />

approach to insulation, another great column from MIMA and a<br />

great article from the insulate team on “What insulation<br />

manufacturers are not” If you are reading this in print, head over<br />

Cover Story<br />

When is an<br />

Insulation Manufacturer...<br />

Not an insulation manufacturer? No, it’s not the set-up for a bad joke! All construction<br />

projects, even the smallest domestic extensions, feature many different voices either<br />

asking for information or offering advice. For any project to be a success, good<br />

communication between those voices is vital. By <strong>Insulate</strong> <strong>Magazine</strong>.<br />

Alas, ‘communication’ doesn’t necessarily<br />

translate into ‘collaboration’, meaning the shared<br />

goal of creating a quality, comfortable and<br />

efficient end product can get lost. With varying<br />

levels of knowledge and confidence, it can be<br />

difficult for people - particularly those with<br />

limited experience of construction - to know<br />

which voices to listen to.<br />

The imperative for insulation manufacturers to<br />

demonstrate the performance of their products<br />

to meet thermal regulations sees them thrust to<br />

the forefront of the process. A side effect is that<br />

their advice is sought on all aspects of the<br />

constructions where their products are<br />

used - even when that guidance should be<br />

sought from other professionals.<br />

SAP Assessors<br />

It’s the question that comes up time and again:<br />

“What U-value do I need to achieve?”<br />

For refurbishment and extension projects, it’s a<br />

relatively easy question to answer. Work to existing<br />

buildings takes an elemental approach with<br />

each part of the building looked at in isolation.<br />

Each country’s Building Regulations set out<br />

defined targets for individual construction<br />

elements and, in the majority of cases, nothing<br />

else needs to be addressed.<br />

New buildings require a more holistic approach.<br />

The performance of the whole ‘package’ -<br />

U-values, air tightness, heating, renewables,<br />

solar gains etc. - is assessed in combination.<br />

Specifications can be tweaked to optimise the<br />

design and, where U-values are concerned,<br />

improved performance in one element can offset<br />

a shortfall in another.<br />

The energy efficiency of new buildings has<br />

been assessed this way for a decade or more<br />

throughout the UK, but there are times when the<br />

concept remains an alien one. For people not<br />

used to working with regulations day in, day out,<br />

manufacturers are more likely to be the first port<br />

of call.<br />

We don’t know how the buildings<br />

we produce are performing<br />

www.insulatenetwork.com<br />

Insulation companies might employ people<br />

experienced in carrying out SAP and SBEM<br />

calculations; they may even partner with<br />

companies who provide energy assessment<br />

services. But, unless the customer is copying the<br />

‘notional dwelling’ specification, a manufacturer<br />

is unlikely to be able to definitively state what<br />

U-values should be met.<br />

Those notional specifications provided in the<br />

Building Regulations for England, Wales and<br />

Scotland provide a starting point. Experienced<br />

assessment professionals can refine those<br />

specifications based on experience and common<br />

construction practice, but for new build projects<br />

SAP or SBEM calculations must<br />

define the performance of individual elements.<br />

Any U-value target suggested by an<br />

insulation manufacturer is therefore precisely that:<br />

a suggestion.<br />

Chartered surveyors /<br />

building inspectors<br />

The potential scenarios that result in<br />

insulation manufacturers being asked to give<br />

their blessing to work are too numerous to be<br />

explored individually in this word count, but can<br />

involve some or all of the following:<br />

- A lack of knowledge, experience or confidence when installing or inspecting insulation.<br />

- Not enough appreciation of what low energy construction requires or looks like.<br />

- An attitude of ‘I’ve always done it this way’.<br />

- Shortcuts taken or product substitutions made due to time or cost pressures.<br />

- Poor communication between parties involved on the project.<br />

The only independent insulation industry trade magazine<br />

This feature was conceived as a lighthearted<br />

examination of the times when too much is asked<br />

of insulation manufacturers. When it comes to<br />

the quality of our built environment, however, it’s<br />

difficult to avoid being entirely serious.<br />

It’s no exaggeration to state that the performance<br />

gap - the disparity between a building’s intended<br />

thermal comfort and efficiency at design stage,<br />

and how it behaves once constructed - is endemic<br />

within much of UK construction. Speed of<br />

construction is prioritised over quality; questions<br />

are asked after the event, rather than checking<br />

correct installation procedures before starting.<br />

It speaks to issues of knowledge, skills and training<br />

in the whole construction industry - issues we<br />

are all aware of, but for which solutions always<br />

seem to remain tantalisingly out of reach. For the<br />

majority of projects, post occupancy evaluation<br />

still lacks feasibility. We don’t know how the buildings<br />

we produce are performing.<br />

Checking as-built performance simply isn’t on the<br />

agenda, but unless issues like those listed above<br />

are picked up during the design and construction<br />

phases, the end user will be saddled with an uncomfortable<br />

building and high energy bills. And,<br />

as events in <strong>2017</strong> have shown us, these sorts of<br />

compromises do not just risk compliance with<br />

energy efficiency requirements…<br />

Too often, poor insulation installation is<br />

only picked up once it is too late. When<br />

a problem is raised, when the original intent<br />

has not been met, the aim becomes<br />

to find the ‘best’ compromise solution.<br />

when the original intent has not been met, the aim<br />

becomes to find the ‘best’ compromise solution.<br />

You can’t blame people for being reluctant to take<br />

down work that has already been done, but you<br />

can question why every step wasn’t taken to ensure<br />

the work was done correctly from the outset.<br />

Photographs are emailed from site; restricted<br />

views of small areas of the build. “The building inspector<br />

is happy if you say this is okay,” comes the<br />

accompanying request. Insulation manufacturers<br />

understand how their products should be used as<br />

well as, if not better than, anybody. But they can<br />

only comment on whether an installation meets,<br />

or appears to meet, their recommendations.<br />

That isn’t to pick on Local Authority Building<br />

Control or Approved Inspectors. It is to demonstrate<br />

the importance of all professionals working<br />

together and enjoying proper collaboration, rather<br />

than hoping manufacturers have magic wands<br />

capable of curing on site conflicts.<br />

Too often, poor insulation installation is only picked<br />

up once it is too late. When a problem is raised,<br />

Next month, part two of this feature<br />

will look at how far insulation<br />

manufacturers can go in helping<br />

with architectural and structural<br />

design.<br />

Aspirational Action Plan<br />

for our Goverment to make<br />

our Buildings Great Again<br />

Sarah Kostense-Winterton Executive Director, MIMA<br />

With the Clean Growth Plan on the<br />

cusp of publication and with onethird<br />

of UK carbon emissions still<br />

coming from buildings, a major industry alliance¹,<br />

the Energy<br />

Efficiency Infrastructure group (EEIG) has<br />

called for an ambitious new buildings infrastructure<br />

programme to help to decarbonise<br />

the UK’s buildings, deliver major energy<br />

savings to consumers whilst also providing a<br />

much-needed boost to the UK economy.<br />

Buildings Energy Infrastructure Programme<br />

Commissioned by the EEIG, the Frontier Economics<br />

report, “Affordable Warmth, Clean Growth”,<br />

recommends a comprehensive Buildings Energy<br />

Infrastructure Programme and dedicated delivery<br />

agency to achieve major energy savings and<br />

de-carbonise the UK heating supply. The report<br />

clearly sets out an action plan for the Government<br />

to make all homes energy efficient within 20 years.<br />

Achieving this goal will require the adoption of<br />

world-leading quality standards for retrofitting and<br />

constructing homes, area-based schemes led by<br />

local authorities, additional funding sources that<br />

won’t raise energy bills and financial incentives to<br />

encourage households to take up energy-saving<br />

measures.<br />

19 Million Homes<br />

There are still 19 million homes in the UK with<br />

needlessly poor levels of energy performance -<br />

below an EPC C rating – and up to a quarter of<br />

the energy consumed in homes could be saved<br />

cost-effectively, with the technical potential for energy<br />

use in homes to be cut in half.<br />

Cuts and Crashes<br />

Despite this, the level of funding for energy<br />

efficiency measures has been cut by a huge 50%<br />

since 2012 and the number of major insulation<br />

and efficient heating measures being installed has<br />

crashed by 80%. The EEIG alliance is calling on<br />

the Government to reverse that fall and to make<br />

buildings’ energy performance a capital infrastructure<br />

investment priority.<br />

10<br />

insulatenetwork


www.insulatenetwork.com<br />

Aspirational Action Plan<br />

To achieve this much-needed reverse the<br />

report makes key recommendations which include:<br />

- A target for all homes to be brought up to an energy performance rating of C (on the A<br />

to G scale) by 2035, with all low-income households achieving a C rating by 2030.<br />

- A requirement for new homes to be constructed to a zero-carbon standard by 2020.<br />

Subsidies for all low-income home-owners to make energy efficiency renovations to their<br />

properties.<br />

- A demonstrator programme to test the most attractive schemes to unlock able-to-pay<br />

households’ investment in energy saving renovations, including zero interest loans, low<br />

interest equity loans you don’t have to pay back until a home is sold and salary sacrifice<br />

schemes like those for childcare vouchers.<br />

- Changes to Stamp Duty to encourage renovations when people move home.<br />

- Tax allowances for private landlords and 50% subsidies for social landlords to undertake<br />

energy efficiency renovations.<br />

- Strengthening regulation in the private rented sector from 2025 to prevent landlords<br />

from renting out homes which have below average energy performance.<br />

- Applying sensible minimum standards when homes are sold to help address health<br />

risks and deaths caused by excessive cold.<br />

The regulations and minimum standards, properly<br />

enforced, can significantly bring down the cost<br />

of the programme to the public purse.<br />

The Rt. Hon. Lord Deben, author of the<br />

report’s Foreword and supporter said:<br />

“This is market failure at its most pernicious and<br />

the Government needs to intervene to make the<br />

free market work.<br />

This is a properly constructed infrastructure<br />

programme that provides a cost-effective way<br />

of meeting our climate change objectives while<br />

significantly reducing the cost of living for a huge<br />

proportion of the population”.<br />

www.insulatenetwork.com <strong>11</strong>


www.insulatenetwork.com<br />

Claire Thornhill, of Frontier Economics<br />

commented:<br />

“Buildings are an integral part of our energy<br />

infrastructure system. If we are to de-carbonise in<br />

a cost-effective way and keep energy bills as low<br />

as possible we need an integrated and ambitious<br />

infrastructure programme to de-carbonise our<br />

buildings.<br />

The Plan would require public investment in<br />

household energy efficiency to be increased by<br />

£1.1 billion per year – from £0.6 billion today to<br />

£1.7 billion. A previous Frontier Economics report<br />

that analysed Government data found that an<br />

energy efficiency programme achieves comparable<br />

economic returns to other infrastructure<br />

programmes.”<br />

Buildings Energy Performance Missing<br />

The Government plans to spend £170 billion on<br />

housing, economic infrastructure and R&D<br />

programmes up until 2021/22. However, buildings<br />

energy performance does not yet feature in<br />

the Government’s infrastructure plans despite the<br />

fact that it would help households to save on<br />

average £270 every year off their energy bills,<br />

boost the economy and reduce the need for new<br />

energy supply infrastructure investment<br />

elsewhere. The Building Energy Infrastructure<br />

Programme is designed to leverage in £3.9 billion<br />

of private investment per year.<br />

This compelling report will be launched on 27th<br />

September, followed by a Parliamentary launch<br />

on 16th <strong>October</strong> – an event sponsored by one<br />

of our supporters, Conservative MP Antoinette<br />

Sandbach along with a tri-All Party Parliamentary<br />

Grouping of PRASEG, Intelligent Energy and Fuel<br />

Poverty and further supported by Lord Deben.<br />

Parliamentarians will be introduced with a complete,<br />

long-term and high quality energy efficiency<br />

plan as well as opportunities to publically show<br />

their support at the event.<br />

Message to the Govenment<br />

Our message to the Government is to support<br />

this achievable commitment to keeping energy<br />

costs in British homes and buildings down and<br />

deliver a high quality, sustainable programme.<br />

A programme that can restore business and<br />

consumer confidence and unleash private investment<br />

in the industry - ensuring long-term<br />

improvements in buildings energy performance.<br />

Now let’s see Government work with us to make<br />

this happen and ensure that the benefits of raising<br />

the building energy performance of our buildings<br />

are grasped – from the lasting reductions<br />

in fuel bills and fuel poverty to meeting carbon<br />

reduction targets and economic growth. This<br />

Programme will surely make our buildings great<br />

again and make us proud, resulting in an industry<br />

prepared and future-fit and with a solid basis of<br />

consumer confidence going forward.<br />

Sarah Kostense-Winterton is<br />

Executive Director of MIMA, the Mineral Wool<br />

Insulation Manufacturers Association and provides<br />

the secretariat to the Energy Efficiency Infrastructure<br />

Group (EEIG).<br />

The Key to Easy, All-in-One Certfication<br />

The British Board of Agrément makes life easier for manufacturers<br />

of doors and windows products by providing the right industry<br />

assurances, all under one roof.<br />

You could say that for the majority of<br />

people windows and doors are arguably<br />

the most regularly encountered features of<br />

everyday life. Yet usually we hardly notice<br />

them. But if something goes wrong, we’re<br />

soon keen to put it right. The safety of<br />

fenestration products should never be<br />

taken for granted. In fact, every component<br />

of any building needs to be thoroughly<br />

checked for quality and safety.<br />

So for manufacturers of new products,<br />

it’s vital to get the specifications on<br />

windows & doors right from the start.<br />

Establishing any product’s fitness for use<br />

can take some time and you often need a<br />

number of separate certificates, as most<br />

Certification Bodies only certify to individual<br />

national Standards.<br />

Not so with the BBA. With a BBA Certificate,<br />

all relevant Building Regulations<br />

are considered along with other requirements<br />

like Codes of Practice and NHBC<br />

requirements, so manufacturers can satisfy<br />

themselves that all levels of fitness for use<br />

have been met without the need for multiple<br />

Certificates. That means choosing the<br />

BBA saves time, money and hassle.<br />

Above & Beyond<br />

Additionally, BBA Assessments go<br />

above and beyond what is required from a<br />

national standard, in<br />

particular with reference to Regulation<br />

7 in England and Wales - Materials and<br />

workmanship or Regulation 8 in Scotland<br />

– Durability, workmanship and fitness of<br />

materials.<br />

The BBA carries out durability tests such<br />

as resistance to UV, heat, water and<br />

impact. BBA Certificates also involve<br />

bi-annual factory audit visits to ensure<br />

factory production control is continuing<br />

to manufacture a quality product to the<br />

right specifications.<br />

The BBA also has its own UKAS accredited<br />

testing facilities, so technicians can see firsthand<br />

how a window and door performs and<br />

how suitable it would be for the market.<br />

With a BBA Certificate, manufacturers have<br />

confidence that the product satisfies all relevant<br />

Building Regulations, making life easier<br />

for specifiers when choosing the right fenestration<br />

products.<br />

50 years’ experience in Windows and Doors<br />

and the associated Building Regulations<br />

involved within them means the BBA is well<br />

versed in understanding what the requirements<br />

are for the domestic and commercial markets.<br />

How We Must Respond<br />

to the Perfect Storm<br />

<strong>Insulate</strong> <strong>Magazine</strong> columnist Simon Storer,<br />

Chief Executive of the British Rigid Urethane Foam Manufacturers Association (BRUFMA)<br />

The hiatus caused by the tragic events of Grenfell, is beginning to settle into a more<br />

considered and empirical approach with regards to the many other high-rise buildings<br />

across the country that have similar external cladding systems to Grenfell.<br />

Find a Solution Together<br />

Whilst the pain, disruption and un-certainty<br />

remains very real for residents, victims and the<br />

wider community in and around the blackened<br />

tower block, most of whom, it appears, have yet<br />

to be re-housed, the construction industry and<br />

other relevant parties, working closely with DCLG<br />

need to identify and implement work that must<br />

be carried out to make these building safe and<br />

secure and re-assure residents and owners.<br />

This is not to pre-empt or pre-judge any of the<br />

investigations or inquiries that are underway<br />

regarding the events at Grenfell, or indeed the<br />

(welcome) review of Building Regulations that is<br />

now underway. But more to ensure that all other<br />

buildings meet the current rules and regulations<br />

and we correct the shortcomings and<br />

questionable decision making that seems to be<br />

prolific across the country.<br />

a combination of mistakes from many quarters<br />

coming together to create a perfect storm<br />

Orderly and Considered Approach<br />

With so many domestic high-rise buildings listed<br />

as being ‘unsafe’ – and who knows how many<br />

non-domestic buildings will be added to this list<br />

– there needs to be an orderly and considered<br />

approach to prioritise these buildings and the<br />

work needed; those that are high-risk through<br />

to low risk, based on a range of criteria for each<br />

building.<br />

These criteria will include inter alia, if a building<br />

has a separate fire escape and its number of<br />

exits; fire suppression such as sprinkler systems;<br />

fire doors; alarm systems; extinguishers; cleared<br />

stairwells; the type of residents – for instance if<br />

they are elderly or disabled; and instructions from<br />

building management in the case of an<br />

emergency.<br />

Considered Approach<br />

Once this information is established, the<br />

necessary work can be carried out applicable to<br />

16<br />

www.insulatenetwork.com


The Perfect Storm<br />

each building, based on its own individual merits.<br />

This should eradicate condemning buildings unnecessarily,<br />

because of knee-jerk reactions and<br />

poorly informed opinions.<br />

No Complacency<br />

We must not be complacent, but fortunately<br />

Grenfell is a very rare event and is likely to have<br />

been a combination of mistakes from many<br />

quarters coming together to create a perfect<br />

storm. Although we must of course wait for the<br />

Inquiry to establish what those mistakes and<br />

errors of judgement were for Grenfell, we will<br />

continue to build new buildings and refurbish<br />

existing buildings, including those earmarked<br />

because of Grenfell. Construction has got to<br />

meet the needs of society together with hitting<br />

targets for energy efficiency and energy performance<br />

of buildings that the country must<br />

achieve. The construction industry still has work<br />

to do and it will continue to do it.<br />

Full-Scale Fire Tests<br />

As we know a series of full-scale fire tests on<br />

cladding systems were commissioned by DCLG<br />

because of Grenfell. Although these were not<br />

generic tests and the information ascertained is<br />

only relevant to each specific combination of material<br />

tested, useful information was still gained.<br />

Therefore, anyone responsible in specifying<br />

and installing external cladding systems can be<br />

confident that, when used with an approved<br />

mixture of materials, PIR insulation can remain<br />

as the first choice of insulation material on our<br />

buildings. PIR passed a full BS8414 fire test, but<br />

it also provides several other beneficial characteristics,<br />

including high thermal efficiency to help<br />

buildings meet energy efficiency levels that enhance<br />

people’s living conditions and reduce their<br />

energy consumption.<br />

Media in Overdrive<br />

It is not surprising that the media went into overdrive<br />

following Grenfell, that is their job, even<br />

though a great deal of what was written was pure<br />

speculation, inaccurate and wayward. What is<br />

far more distasteful, is the mercenary activities of<br />

those who saw this tragedy as a means of<br />

commercial advantage and were quick to use<br />

selective and questionable data to pedal<br />

half-truths and erroneous claims.<br />

Avoiding False Assumptions<br />

The lessons from Grenfell will be crucially<br />

important, but so is the need to ensure we make<br />

the changes and improvements where they are<br />

needed and that these are not based on false<br />

assumptions or supposition. Only then will our<br />

necessary criteria for future generations<br />

<strong>Insulate</strong> Columnist<br />

A Simple Guide<br />

to Coverall Selection<br />

<strong>Insulate</strong> <strong>Magazine</strong> columnist George Elliott, a technical specialist at science-based technology 3M,<br />

discussses protective coverall selection considerations for your workforce<br />

Within the insulation industry, many professionals work in close proximity to<br />

potentially hazardous chemicals and fibres, whether at the installation site or in the<br />

factory. When these substances come into contact with the skin, they can cause<br />

burns, rashes and related conditions, including dermatitis. Symptoms can include redness,<br />

scaling/flaking, blistering, weeping, cracking and swelling of the skin. For this reason, employers<br />

have a duty to reduce the level of exposure to such contaminants that their employees face.<br />

As with other potential hazards that cannot be<br />

eliminated, the first step should be to act to<br />

limit the hazard itself, either by substituting it for<br />

something less harmful or by introducing engineering<br />

controls. However, in some cases a hazard<br />

will remain even after such measures have<br />

been implemented.<br />

In these instances, full body protective coveralls<br />

may be required. Some people may assume that<br />

all coveralls are alike but there are actually many<br />

points to consider when selecting protective<br />

coveralls, just as there are with other types of<br />

personal protective equipment (PPE).<br />

And as with other types of PPE, the main thing<br />

to remember is that protective coveralls must be<br />

both adequate to protect against the hazards<br />

Adequate<br />

In order to identify those coveralls that are<br />

adequate, the first thing you need to know is the<br />

physical state of the contaminant that you are<br />

dealing with. It could be a liquid, a particulate, or<br />

a mixture of both.<br />

Next, you should consider the form of the contaminant.<br />

This should involve, for example,<br />

checking the percentage concentration of a liquid<br />

chemical.<br />

Additionally, assessment of the type of exposure<br />

workers possibly face should be undertaken.<br />

How much liquid could they potentially come into<br />

contact with? Could it be splash, spray or even<br />

jet exposure?<br />

18<br />

www.insulatenetwork.com<br />

Similarly, you need to know for how long workers<br />

will be exposed to the potential chemical<br />

hazards. Some may only come into contact with<br />

these chemicals occasionally, while others may<br />

work with them throughout their entire shift.<br />

When dealing with liquid chemical hazards, you<br />

should also consider the coverall’s permeation,<br />

penetration and repellence levels. Manufacturers<br />

should be able to provide this information and<br />

other data regarding their product’s performance<br />

when protecting against specific substances.<br />

Once you have gathered all this information, you<br />

can use it to identify what level of protection you<br />

require.<br />

When these substances<br />

come into contact with<br />

the skin, they can cause<br />

burns, rashes and<br />

related conditions,<br />

including dermatitis.<br />

The level of protection provided by a protective<br />

coverall is denoted by the ‘Type’ test they have<br />

undergone. The Type tests are: gas protection<br />

(Type 1), non-gas protection (Type 2), liquid jet<br />

protection (Type 3), liquid spray protection (Type<br />

4), particulate protection (Type 5) and limited<br />

liquid splash (Type 6).<br />

Suitable<br />

Once you have narrowed down your selection of<br />

coveralls to those that are adequate, you must<br />

identify those that are also suitable for the<br />

individual and their working activity.<br />

When it comes to protective coveralls and<br />

suitability, one of the main things to consider is<br />

the thermal comfort of the user. Protective coveralls<br />

that are more breathable will be cooler and<br />

therefore more comfortable. This is important<br />

because employees who find their coveralls comfortable<br />

are more likely to wear them correctly.<br />

Those who don’t are less likely to comply with<br />

PPE requirements by, for example, removing the<br />

19


www.insulatenetwork.com<br />

hood, rolling up sleeves, or partially unzipping the<br />

front. This can leave them exposed to potential<br />

hazards.A protective coverall’s breathability will<br />

depend largely on the material it is made from.<br />

Usually, protective coveralls are made from either<br />

SMS (spunbond-meltblown-spunbond) fabrics or<br />

laminate materials.<br />

SMS fabrics combine layers of polypropylene that<br />

can filter out certain chemicals and dry<br />

particulates, but still offer some porosity for<br />

breathability and comfort.<br />

Laminate materials usually consist of a<br />

polyethylene film laminated onto a non-woven<br />

polypropylene base. These afford greater<br />

chemical and liquid protection, but less<br />

breathability, than their SMS counterparts.<br />

So, it can be seen that a coverall’s breathability<br />

can be unfortunately inversely proportional to the<br />

level of protection it can provide.<br />

To strike a balance between protection and comfort,<br />

3M offers protective coveralls made predominately<br />

from laminate fabric, but with a breathable<br />

SMS back panel. 3M is happy to provide<br />

companies with product samples so that their<br />

employees can trial them in their normal working<br />

conditions.<br />

Other features that can improve comfort include<br />

knitted cuffs, which are softer than elasticated<br />

ones, and elasticated waistbands, which enable<br />

improved protection whilst moving.<br />

Features that can improve functionality include<br />

three-panel hoods, which stay on better when<br />

the wearer turns their head than the two-panel alternatives,<br />

and different coloured coveralls, which<br />

can help to differentiate those workers who are<br />

exposed to particularly dangerous hazards from<br />

others.<br />

With so many things to consider, the selection<br />

process may at first seem daunting, but it needn’t<br />

be. If in doubt, seek advice. 3M’s experts are<br />

always happy to help you to decide which coveralls<br />

will be best for your workplace.<br />

Working to the<br />

Right Standard(s)<br />

U-values are an integral part of everyday life for the construction industry. Sometimes the<br />

success of a project can hinge entirely on hitting the thermal targets for the building’s<br />

envelope. By extension, that magnifies the importance of proving a specification’s ability<br />

to meet its target - and being able to trust in the answer provided. By <strong>Insulate</strong> <strong>Magazine</strong>.<br />

Which is where U-value calculations come in: all-important pieces of paper providing the required proof.<br />

There are many and various standards relating to calculations, so for the purposes of providing an overview<br />

we’ve used those listed by the British Board of Agrément (BBA) as applicable to their ‘Scheme for<br />

U-value Calculation Competency’ as a framework.<br />

ISO 6946<br />

For all that this international standard might be<br />

seen as defining how the majority of U-value<br />

calculations are done, it is actually surprisingly<br />

narrow in its scope. The document’s own text<br />

limits itself to walls and roofs!<br />

Nevertheless, it forms the basis for many of<br />

the calculations that insulation manufacturers<br />

and energy assessment professionals produce,<br />

supplemented by a variety of other guidance<br />

that we’ll come to shortly. Known as the ‘combined<br />

method’, ISO 6946 describes a simplified<br />

tool capable of establishing the performance of<br />

constructions for the purposes of comparison,<br />

or helping determine compliance with thermal<br />

regulation targets.<br />

A detailed calculation method is also referred to,<br />

defined in ISO 102<strong>11</strong>. Numerical modelling carried<br />

out to that standard uses specialist software<br />

and tends not to be a widely-offered service, so<br />

we’re not going to cover it in detail here. However,<br />

when the majority of calculations are done<br />

the ‘simplified’ way, it is easy to forget there are<br />

alternative, more complex methods which provide<br />

additional data such as minimum surface<br />

temperatures. Obtaining a calculation done using<br />

the combined method is relatively straightforward<br />

- but that isn’t to say it is always the most<br />

appropriate method.<br />

23<br />

www.insulatenetwork.com 23


Ignoring complexities in a proposed construction<br />

for the sake of convenience, and trying<br />

to represent them without using numerical<br />

modelling, risks making the calculation result<br />

unrepresentative of what will be achieved in<br />

practice.<br />

So what does ISO 6946 allow for?<br />

It is best suited to building elements with layers<br />

of consistent thickness and uniform thermal<br />

properties (“homogenous layers”), but also<br />

provides ways of dealing with inhomogenous<br />

layers. It can include for the thermal properties<br />

of air layers up to 300mm in thickness,<br />

but can’t allow for metal components bridging<br />

insulation layers.<br />

There is a correction factor available for metal<br />

fixings, however, as well as one for air gaps<br />

in insulation layers; if these corrections total<br />

more than 3% of the calculated U-value then<br />

the result is amended to reflect the impact on<br />

performance. Finally for the purposes of this<br />

overview, there is an annex describing how<br />

tapered insulation layers can be calculated,<br />

providing a means of establishing the thermal<br />

transmittance of cut-to-falls roofing schemes.<br />

While ISO 6946 describes how to carry out<br />

combined method calculations, it doesn’t offer<br />

much guidance on what to include in them...<br />

BRE Report BR 443<br />

… which is where this free-to-download<br />

document comes in, providing essential information<br />

appropriate conventions to use when<br />

calculating U-values. It should be familiar to<br />

anybody who provides a calculation service.<br />

24


www.insulatenetwork.com<br />

The report is being revised to reflect new and<br />

updated practice, but at the time of writing the<br />

2006 edition remains current.<br />

BR 443 is also listed as a ‘source of data’ by the<br />

BBA, along with a couple of other standards,<br />

current BBA certificates, and recognised declarations<br />

by manufacturers.<br />

If specific material data is missing from a particular<br />

specification, these data sources can provide<br />

appropriate assumptions to maintain a level of<br />

accuracy in the calculation.<br />

ISO 13370<br />

Here is the standard that complements ISO 6946<br />

and provides the means of calculating heat loss<br />

through ground floors, or what is described in<br />

the standard as the “three-dimensional nature”<br />

of heat flow in the ground. It applies to slab-onground<br />

constructions and ventilated suspended<br />

floors.<br />

Heat transfer into the ground is affected by the<br />

thermal properties of the ground itself, the area<br />

of the floor, and the perimeter of the floor including<br />

thermal bridging at its edge. If you request<br />

a ground floor calculation you will be asked for<br />

measurements of the floor’s area and length of<br />

exposed perimeter for this reason.<br />

BRE Digest 465<br />

This Digest, developed jointly by the BRE and the<br />

Steel Construction Institute, provides a methodology<br />

for calculating the thermal transmittance for<br />

warm, cold and hybrid steel frame constructions<br />

that otherwise fall outside the scope of ISO 6946.<br />

Validated by detailed calculations to ISO 102<strong>11</strong>,<br />

it allows a simplified method to be incorporated<br />

into common software tools and provides a<br />

means of assessing steel frame constructions<br />

more widely.<br />

SCI Information Sheet P312<br />

This information paper also adapts the procedure<br />

in ISO 6946; in this case, to provide a relatively<br />

simple means for calculating built-up metal roof<br />

and wall cladding constructions featuring rail and<br />

bracket spacers. The differences in calculation<br />

method account for a compressed insulation<br />

layer, as well as the impact of linear and point<br />

thermal bridging due to metal components and<br />

fixings, all validated by calculation to ISO 102<strong>11</strong>.<br />

BRE Information Paper IP 10/02<br />

Another document dealing with the effect of<br />

metal components on insulation layers, this paper<br />

offers a method for determining the thermal<br />

performance of insulated double skin metal roof<br />

and wall systems that incorporate ‘z’ spacers.<br />

It accounts for the thermal bridging of the metal<br />

connectors between the inner liner and outer<br />

sheet.<br />

In Conclusion<br />

For all the talk of ‘simplified methods’, calculating<br />

U-values remains a largely specialist activity. If a<br />

calculation says a certain result will be achieved<br />

then the majority of readers will assume it to be<br />

correct. The quality of a calculation depends as<br />

much on the information provided at the outset,<br />

and the ability of the person doing the calculation,<br />

as it does on the standard used to perform<br />

the calculation. Which is why, next month, we will<br />

look at some typical calculations to illustrate how<br />

they display their data.<br />

<strong>Insulate</strong> Debate<br />

Warm Flat Roofs<br />

are Simply the Solution when it<br />

Comes to Quality and Performance<br />

warm flat roof, correctly designed, specified and built, is one of the simplest construction<br />

A elements of the building envelope, writes Paul Forrester, Technical Services Manager at<br />

PIR insulation manufacturer, Recticel. However, its performance remains reliant upon a basic,<br />

but essential value: high-quality workmanship.<br />

Structural deck, vapour control layer, insulation<br />

and waterproofing combine to create a warm flat<br />

roof; the perfect example of a fabric-first<br />

approach in action. It’s a tried-and-tested<br />

solution, not least because it keeps the roof<br />

structure at or around the same temperature as<br />

the building interior. This eliminates the<br />

possibility of condensation occurring - which<br />

could otherwise cause deterioration of the<br />

structure - and ensures the roof performs for the<br />

building’s intended lifespan. And yet questions<br />

such as, “Does a roof need a vapour barrier?”<br />

continue to be asked, highlighting that<br />

misapprehensions remain about the<br />

ramifications of flat roof design. Too often, poor<br />

roofing performance results from a lack of<br />

awareness good-practice principles.<br />

A warm flat roof, correctly<br />

Space Consideration<br />

Compromises can also be<br />

caused by on-site constraints,<br />

a good example being that of<br />

hybrid roofs. Imagine a flat roof<br />

constructed on timber deck<br />

and joists: it’s not surprising<br />

that people sometimes look at<br />

the space between joists and<br />

wonder if it can be filled with<br />

additional insulation. If there is<br />

a restriction on the thickness<br />

of insulation that can be<br />

accommodated above the<br />

structure, then the temptation<br />

to utilise the extra space is<br />

even greater.<br />

However, problems can<br />

occur if a standard warm roof<br />

is designed and constructed,<br />

but with additional insulation<br />

incorporated below the deck.<br />

Not only is a vapour barrier or<br />

vapour control layer (VCL), a<br />

vital component of the roof, it<br />

must be correctly positioned -<br />

on the warm (internal) side of<br />

all the insulation. There are<br />

numerous reasons why<br />

incorrect placement of<br />

insulation relative to the VCL<br />

should be avoided, perhaps<br />

best summarised in the<br />

foreword of BS 5250:20<strong>11</strong> +<br />

A1:2016 Code of practice for<br />

the control of condensation in<br />

buildings, which states:<br />

‘Bearing in mind that<br />

occupants often fail to use<br />

buildings<br />

There are numerous reasons<br />

why incorrect placement of<br />

insulation relative to the<br />

Vapour Control Layer (VCL)<br />

should be avoided<br />

in the manner intended, be it by choice, lack of<br />

understanding or force of circumstance,<br />

designers are advised to err on the side of<br />

caution and adopt robust, fail-safe solutions.’<br />

Label with care<br />

To that end, section H.2 of the standard lists<br />

three acceptable scenarios for the placement of<br />

insulation in a flat roof: cold roof, warm roof and<br />

inverted roof. Nowhere does it support the<br />

design and construction of hybrid flat roofs.<br />

Some insulation manufacturers, however, are<br />

happy to advocate hybrid constructions, usually<br />

when the balance of the two insulation<br />

thicknesses is considered to be “correct”, i.e. the<br />

layer of insulation between the joists does not<br />

have higher thermal resistance than the layer of<br />

insulation installed over the deck.<br />

A condensation risk carried out in accordance<br />

with the method detailed in BS EN ISO 13788<br />

insulatenetwork<br />

27


www.insulatenetwork.com<br />

- Hygrothermal performance of building components<br />

and building elements - may appear to<br />

show no risk. However, the fact that BS 5250<br />

does not support the construction type means<br />

that we believe insulation manufacturers should<br />

label any condensation risk analysis for a hybrid<br />

flat roof as ‘not recommended’.<br />

Consider as well another reason to doubt the<br />

appropriateness of this analysis of a hybrid flat<br />

roof solution. Section 4.2 of BS 5250 states: ‘BS<br />

EN ISO 13788 considers only the risks<br />

arising from the diffusion of water vapour through<br />

the building fabric; it does not take account of<br />

the much greater risk of condensation occurring<br />

as a result of air leakage, which<br />

transports water vapour through gaps, joints and<br />

cracks in the building fabric.’<br />

By its very nature, a hybrid roof that features<br />

insulation fitted between timber joists<br />

introduces the potential for air gaps. Section<br />

A.3 is clear that, ‘the rate at which moisture is<br />

transported by air movement, where it occurs,<br />

is much greater than that of transportation by<br />

diffusion.’ A condensation risk analysis cannot<br />

adequately allow for the standard of<br />

workmanship, and a high level of workmanship<br />

in itself would not mitigate potential issues.<br />

If anybody is to make a judgement on the<br />

levels of workmanship, and whether it makes the<br />

construction method any more acceptable for a<br />

particular project, it should be the<br />

designer, building inspector or end user. The<br />

insulation manufacturer can advise on the<br />

interpretation of a condensation risk analysis<br />

for a hybrid roof, but first and foremost should<br />

promote the fundamental principles of good roof<br />

design outlined in BS 5250.<br />

the correct VCL position, some might ask if a<br />

hybrid roof is acceptable if the VCL is moved to<br />

ceiling level behind the internal plasterboard<br />

finish. While technically that might satisfy the<br />

basic requirements, we would urge practical<br />

thinking: are light fittings or other services going<br />

to be installed in the ceiling? Can the continuity<br />

of the VCL – vital to its performance – be<br />

guaranteed?<br />

It only takes the building’s next owner to want to<br />

change something and that VCL could be<br />

compromised as part of any works to the ceiling.<br />

Will anybody make sure it is restored to its<br />

original condition? If a VCL cannot be relied upon<br />

to mitigate the risk of condensation then the roof<br />

design cannot be considered appropriate, and<br />

there are precious few alternative<br />

solutions.<br />

Despite the best efforts of many to promote the<br />

advantages of service voids – airspaces between<br />

ceiling and VCL, where services can be installed<br />

and the ceiling altered without risking the<br />

integrity of the VCL – few seem willing to employ<br />

them. There are several reasons why: extra time<br />

and materials to construct, restrictions on<br />

headroom etc; all of which serve to highlight why<br />

it is best to keep things simple.<br />

One of the positive aspects of a warm roof is that<br />

the VCL can be installed with the<br />

confidence that it will perform for as long as the<br />

roof performs – hopefully for the lifetime of the<br />

building. That’s why we referred to it as a good<br />

example of fabric first construction, and it’s why<br />

we believe it should always be preferred over a<br />

hybrid alternative.<br />

Considering one of those principles is to ensure<br />

New Knauf Insulation Appointment<br />

Insulation manufacturer, Knauf Insulation,<br />

has appointed a new product manager to<br />

lead the development of its Glass Mineral<br />

Wool range.<br />

Lisa Richardson brings 17 years’ experience in<br />

product marketing to her role with the St Helensbased<br />

manufacturer. She joins from Werner Co.<br />

where she was responsible for product managing<br />

its Werner, Youngman and Abru ladder ranges.<br />

Prior to that she, she worked with a number of<br />

product categories, including hand tools, personal<br />

protective equipment, security and plumbing<br />

fittings.<br />

In her new role, Lisa will be responsible for working<br />

with customers to grow Knauf Insulation’s glass<br />

How Smart Meters can Help<br />

Your Small Installation Business<br />

to Make Big Energy Savings<br />

<strong>Insulate</strong> <strong>Magazine</strong> columnist Claire Maugham,<br />

Director of Policy and Communications at Smart Energy GB<br />

Britain is getting smarter. Our country<br />

is working together to build a greener<br />

and more energy efficient future.<br />

There has never been a better time for small<br />

businesses in the installation industry to get<br />

involved.<br />

Smart meters are available to every household in<br />

Britain, but did you know that many small<br />

businesses can also upgrade to the new system?<br />

According to the Department for Business,<br />

Energy and Industrial Strategy, the average SME<br />

could reduce its energy bill by 18-25 per cent by<br />

installing energy efficiency measures. It is reported<br />

that this would result in an average return on<br />

investment in less than 18 months.<br />

Smart meters automatically send accurate meter<br />

readings, and show you exactly how much energy<br />

you’re using, in near-real time and in pounds<br />

and pence. Helping you to budget, manage, and<br />

keep track of your energy costs.<br />

With the construction industry as a whole making<br />

up around 18 per cent of all small to medium<br />

enterprises in the UK, smart meters, if adopted<br />

In addition to monitoring energy use with a smart<br />

meter, there are also other measures you can<br />

take to prevent energy waste. Smart Energy GB<br />

have worked with the Carbon Trust on a full list of<br />

energy saving tips specifically for small businesses<br />

in the construction industry, detailed right.<br />

If your business has fewer than 10 employees,<br />

you may be eligible to upgrade to a smart meter<br />

at no additional cost; others may need to pay<br />

a small charge for the installation or access to<br />

data.<br />

Your supplier will tell you about any charges up<br />

front. Contact your energy supplier today about<br />

arranging your installation.<br />

Dr. Paul Swift from the Carbon Trust<br />

gives his tips on how construction firms can get smart about energy.<br />

Make smart plans: Be ready to advise clients on how to reduce their future energy bills, through options<br />

such as LED lighting or choice of building materials. Get smart meters installed in new builds.<br />

Look after your tools: Use tools according to guidelines and only run them when needed. Badly<br />

maintained equipment uses more energy and is more likely to fail, so get them regularly PAT-tested and<br />

clean filters and air intakes.<br />

Energy management: Install controls that allow you to turn off site areas not in use. Ensure any damaged<br />

cables or unused connections are removed. If you need a generator, size correctly to prevent wasting money<br />

on fuel.<br />

Understand your energy consumption: Getting a smart meter installed on your business premises helps<br />

track energy costs and budget spend. Use your smart meter to identify patterns, find unexpected spikes<br />

and encourage energy saving both on and off site.<br />

Scheduling: Plan to use equipment in one run, rather than a series of bursts. Get a temporary<br />

connection to the electricity grid as soon as possible!<br />

A Strategic Approach to Energy<br />

and Sustainability Statements<br />

Balancing environmentally sound<br />

proposals with commercial viability<br />

can present a number of challenges<br />

and is further complicated by planning requirements.<br />

With many local planning authorities<br />

now requiring an energy and / or<br />

sustainability statement to be submitted as<br />

part of a planning application, Darren Evans<br />

of Darren Evans Assessments explains why<br />

a well prepared, professional statement will<br />

play a critical role in ensuring planning<br />

consent for a site.<br />

The purpose of the planning system is to contribute<br />

to sustainable development, which has<br />

economic, social and environmental dimensions.<br />

The main aim of an energy and or sustainability<br />

statement is to promote high standards of design<br />

and to reduce the environmental impacts of new<br />

developments. The requirements of these statements<br />

are set regionally and will differ from council<br />

to council across the UK.<br />

An energy statement will involve demonstrating<br />

a specified reduction in energy demand or CO2<br />

emissions beyond building regulations. This is<br />

usually through the use of onsite renewable or<br />

low/zero carbon technologies with examples<br />

including solar PV, solar thermal, air / ground<br />

source heat pumps and biomass boilers.<br />

A sustainability statement will incorporate these<br />

reductions but include additional requirements<br />

such as flood risk assessments, water consumption<br />

targets, transport and cycle storage, on site<br />

recycling, district heating connections and in<br />

depth feasibility studies for additional renewable<br />

and low/zero carbon technologies.<br />

A Local Plan<br />

With regional differences in requirements for energy<br />

statements the point could be argued that<br />

these planning policies do not go far enough in<br />

terms of sustainability. For example, Bristol City<br />

Council require a 20% reduction in CO2 through<br />

on site renewable technologies whist the bordering<br />

council South Gloucestershire has no requirements<br />

for an energy or sustainability statement.<br />

A good example of where planning policies are<br />

going further in terms of sustainability is London<br />

where all new housing must follow the guidelines<br />

of the London plan, regardless of which borough<br />

the development lies.<br />

The London plan requires that a sustainability<br />

statement must be undertaken which amongst<br />

other requirements demands a 35% reduction in<br />

emissions over building regulations. Interestingly,<br />

this does not have to be through renewables or<br />

low/zero carbon technologies, although it is very<br />

difficult to achieve solely through a fabric first<br />

Design for Energy Efficiency<br />

approach. The planning departments which fall under<br />

the London plan can then dictate if they choose to,<br />

reductions through the use of renewable technologies<br />

or other polices such as communal heating systems<br />

or the ability to connect to future district heating<br />

schemes.<br />

“Most projects that come to us for sustainability or<br />

energy statements will not initially meet the requirements<br />

outlined in the local planning policies and we<br />

will propose different options on how to comply that<br />

work with the development both practically and financially,”<br />

commented Darren Evans.<br />

Some contractors will want to avoid these policies for<br />

varying reasons, some genuine and some not. In this<br />

case, the approach taken is to try and demonstrate<br />

the reduction through a fabric first approach which is<br />

achievable in some areas but as previously mentioned<br />

in London can be very difficult. It also varies from region<br />

to region as to whether a development meeting<br />

the targets through the building fabric and no renewables<br />

will be approved through planning. However,<br />

more often than not the requirements will be strictly<br />

enforced.<br />

Meeting Energy Targets<br />

With many councils requiring schemes to provide<br />

minimum performance against BREEAM, contractors<br />

are not always up-to-speed on what is required for<br />

this standard and at what stages things need to be<br />

completed. This applies to non-domestic buildings<br />

over 1,000 m2 and the condition is either Very Good<br />

or Excellent and that is what needs to be met.<br />

Darren Evans Assessments<br />

The project teams are not always forthcoming<br />

with BREEAM evidence, and often when they<br />

do send evidence in it is incorrect or<br />

incomplete. With the other pressures of the<br />

build, the BREEAM requirements seem to be a<br />

low priority and it is left until the ‘last minute’ to<br />

get information back to the assessor therefore<br />

making it harder to gather the evidence and<br />

incurring a higher risk of losing credits, which<br />

results in not meeting the necessary BREEAM<br />

rating. This causes great stress to the design<br />

team and even the end client.<br />

In an ideal situation from a sustainability<br />

point of view there should be a requirement<br />

that a given percentage of a dwellings<br />

total energy demand needs to be provided<br />

through on site renewables.<br />

To tackle this, the client could appoint a BREEAM<br />

Accredited Professional /Sustainability<br />

Champion at the early design stages and<br />

throughout the project to ensure the whole<br />

project team are aware of what is needed and<br />

guarantee the design team incorporate the<br />

necessary details into the design drawings and<br />

specifications. This person should also<br />

proactively gather the required information from<br />

the various design team members. This will make<br />

it easier for the Design Stage assessments to be<br />

completed and allow contractors to focus on the<br />

Post Construction Assessment. They can<br />

highlight particular credits where evidence needs<br />

to be collated throughout the project.<br />

member who is dedicated to BREEAM evidence<br />

collation to ensure BREEAM credits are not lost,<br />

so any day-to-day issues or changes can be<br />

assessed. Having regular BREEAM team<br />

meetings, either by phone or in person, to check<br />

the process is moving forward will ensure it<br />

remains a high priority throughout the project.<br />

A Future Policy<br />

To improve the planning situation in relation to<br />

energy and sustainability in the built environment,<br />

it would be beneficial to see a nationwide<br />

policy rolled out which set out the requirements<br />

for these planning conditions. This way it would<br />

not come as a surprise to developers that they<br />

need to include renewable and low/zero carbon<br />

technologies with every development. In an ideal<br />

situation from a sustainability point of view there<br />

should be a requirement that a given percentage<br />

of a dwellings total energy demand needs to be<br />

provided through on site renewables.<br />
