FEATURE ARTICLE: THE NATIONAL INSULATION ASSOCIATION NIA Members…the preferred choice for your insulation projects The National Insulation Association (NIA) is advising why its members should be the preferred choice for specifiers looking for support in the design and delivery of their upcoming refurbishment and new build insulation projects on domestic, commercial and public sector buildings. NIA registered members have significant experience of working with energy suppliers, private and social housing managers, funders, builders, architects and other specifiers in delivering high quality energy efficiency schemes. The NIA’s membership includes the leading manufacturers/system suppliers and installers of cavity wall insulation, solid wall insulation (both external and internal), loft/ roof insulation, floor insulation and draught-proofing so we are able offer a one stop shop. The NIA and its members offer a range of support services to specifiers including: and customer care policies and procedures and financial viability. This provides specifiers and project managers with assurance and peace of mind when choosing an NIA member. “Along with our established Code of Professional Practice (CoPP) for domestic consumers, we also have a CoPP for our members operating in the new build and commercial markets designed to provide clients and specifiers in these sectors with additional reassurance by setting out the quality, standards and professionalism they can expect from an NIA registered member. The Solutions: With around a third of a buildings heat escaping through uninsulated walls, one of the most effective ways of reducing energy consumption is through wall insulation. Cavity Wall Insulation (CWI) involves the mechanical injection of a suitable insulant into the cavity, using a specified system designed to ensure a complete fill. The main materials used by NIA installers are Mineral Wool (Glass or Rock Wool), EPS Bead (Polystyrene bead) and PU Foam (Polyurethane Foam). CWI usually takes less than a day to install and, with all the work • Information, advice and guidance on funding opportunities. • Assistance with the design, specification and delivery of multi property, multi measure upgrades including bespoke solutions. • Access to a national network of qualified installers. • Issue expressions of interest and requests to tender for installation work to NIA members. • An online member directory via its website Neil Marshall, Chief Executive of the NIA commented: “Companies have to meet our strict membership criteria to join the NIA which includes appropriate levels of insurance, relevant accreditations and approvals, Health and Safety 72 SPECIFIERS JOURNAL - SPRING 2018 “We also get specifiers contacting us asking for help in finding insulation companies to carry out work on their behalf. To help with this we have an ‘expressions of interest and tender request’ service. Through this free service we will issue expressions of interest and tender requests to our members on behalf of specifiers and project managers which provide them with the benefit of avoiding the need to contact lots of different companies and therefore immediate, saving time and money.” done from outside the building, the disruption is minimal. For those buildings that do not have cavity walls - solid stone, pre-1944 timber frame and non-traditional, i.e. concrete construction - which lose more heat and energy than any other type of construction, other solutions are readily available. Solid Walls can be insulated with either Internal Wall Insulation (IWI), External Wall Insulation (EWI), or a combination of the two known as Hybrid Wall Insulation (HWI) and any option

will greatly increase comfort, while also reducing energy bills and the associated environmental impact. IWI typically consists of either dry lining in the form of flexible thermal linings available in 1 metre by 12.5 metre rolls, laminated insulating plasterboard (known as thermal board), or built-up systems with the insulation fitted into a studwork frame. EWI is a tried and tested method of upgrading the thermal performance and external appearance of properties which are literally transformed into warm, energy efficient and attractive homes and buildings. Improving appearance is of particular significance to many local authorities targeting housing projects in areas where they are looking to transform the street or block of flats raising residents’ morale and pride in their community. There are many benefits of EWI including the fact that no interior living space is lost, there is minimal disruption for the residents as the work can be carried out while they are in their homes, there are a wide range of decorative finishes and there is minimal maintenance required once installed. As much as a third of the heat could also be escaping through the roof of a property. Most loft insulation materials work by preventing the movement of heated air through the material. The recommended depth for loft insulation is 270 millimetres for glass wool, 250 millimetres for rock wool or 220 millimetres for cellulose. FEATURE ARTICLE: THE NATIONAL INSULATION ASSOCIATION days when they could be losing valuable heat, as the warm air builds up inside the property is leaking through gaps all of the time. This can have a profound effect, with a typical property losing up to 20% of its heat through air leakage. The Energy Saving Trust reports that by simply installing Cavity Wall Insulation (CWI) savings up to £225* per year can be made on energy bills. If the loft is currently uninsulated, insulation could save up to a further £225* a year – even if there is some loft insulation topping it up to 270mm could save money. The savings are even greater for insulating solid walls, up to £425* per year in a detached home! Draught-proofing windows and doors can also save up to £25* per year and when installed with other measures will greatly increase the comfort in a home. Draught-proofing properties should also be considered as uncontrolled leakage of air through gaps will result in unnecessary heat loss and discomfort to the occupants from draughts. One of these routes is through gaps around windows and doors, and draughtproofing can greatly reduce this leakage.
