The Aircrete Advantage
Thin-Joint System
The Celcon Thin-Joint System combining Celcon’s new Plus
block range of high quality accurately dimensioned aircrete blocks,
with Celfix, a specially developed thin layer mortar.
The System enables the structure of a building to be
constructed faster and to a better quality, allowing follow-on
trades to start work sooner in a weatherproof environment,
whilst retaining the flexibility of on-site construction.
Fully adopted as the preferred method of wall construction
throughout most of Europe, this innovative and
award-winning system has now firmly established itself
within the UK.

In recent years, pressure from stakeholders within the industry
including builders, developers, architects, end users and
Government agencies, require manufacturers to increase both
productivity and quality of build on site whilst retaining
flexibility allowing buildings to be extended or improved.
H+H Celcon prides itself on being at the forefront
of innovative building technology, of which the
Celcon Thin-Joint System is a prime example.
speed, quality and
flexibility
Speed Productivity has become a key aspect in choosing a
construction method. The Celcon Thin-Joint System allows
construction times equivalent to off-site system-build solutions.
This is possible due to the following benefits of the System:
- Increased bond strength
- No mortar ‘swimming’ allowing continued laying
- Ease of mixing and laying mortar
- Highly dimensionally accurate blocks
- Ease of preparing/mixing small quantities
when required
Quality The improvements in build quality gained from
the use of the Celcon Thin-Joint System are:
-
Improved thermal performance
-
Improved stability during construction
-
Improved build accuracy of finished walls
Reduction of site wastage

Flexibility As with traditional building methods, the
construction is carried out on site. This allows the builder to
overcome problems which may have been overlooked at the
design stage and simplifies change to the building should it
need to be extended or adapted to suit future lifestyles:
- Easy to extend or adapt later on
- Construction problems can more easily
be solved on site
- Additional finishes are available
The Celcon Thin-Joint System
Modern Methods of
Construction (MMC)
is a broad based category embracing a
variety of build approaches, including
but not limited to Off-siteManufacture
(OSM). Celcon’s Thin-Joint System has
been quoted as an example of MMC
within the Housing Corporation
Programme Notification PN 06/03
‘Definitions of ‘Build Category’ for
bids and allocation purposes’
(see quote below).
Meeting the criteria as a Non-OSM
Modern Method of Construction the
system incorporates innovative house
building techniques and structural
systems, with the presence of
innovation being an essential feature,
in this instance by traditional
components being combined in
innovative ways.
“ Non-OSM Modern
Methods of
Construction This category is
intended to encompass schemes
utilising innovative housing building
techniques and structural systems
that fall outside the OSM categories.
The presence of innovation is an
essential feature that might manifest
itself through an innovative non-OSM
building system, through a building
technique familiar in other sectors
but new to house-building, or through
traditional components being
combined in innovative ways...
Typically H+H Celcon’s Thin-Joint
System would fall into this category.

The Celcon Thin-Joint System
The Celcon Thin-Joint System can be used for many forms of
construction: cavity walls (inner and outer leaf), solid walls,
walls adjacent to unheated spaces (formerly known as
semi-exposed), partitions, separating walls and foundations.
Thin-Joint diversity
Cavity walls When building with the Celcon Thin-Joint System, the inner leaf of
blockwork can be built first taking the outer leaf off the critical path of the build programme.
This enables internal work to proceed whilst the outer leaf is being constructed, easier
inspection of the cavity and simple installation of any additional insulation required.

Solid external walls Solid wall construction shows the
Celcon Thin-Joint System at its full potential. Applying Celfix Mortar
with either a ‘scoop’ or alternatively with a ‘sledge’, which is specifically
designed for use with solid wall construction, the superstructure of a
dwelling can be completed in 2-3 days. The Celcon Thin-Joint System
offers the designer a choice of solutions with the benefit of both
strength and thermal insulation. The use of thin layer mortar techniques
give greatly improved U-values of up to 20% when compared to
conventional joints in solid external walls and can meet the thermal
regulations without the need for additional insulation.
Partitions Ideally suited for the construction of partition walls, the Celcon Thin-Joint
System adds to the existing benefits offered by Celcon blocks, such as excellent sound
insulation and high fire resistance. With the speed of build and the mortar setting more quickly,
it is possible for the walls to be finished i.e. plastered, without delay. The Celcon Thin-Joint
System also allows greater flexibility and more choice in applied finishes, see Page 17. These
benefits can be further enhanced when Jumbo Plus Blocks are used to build partition walls.
Separating walls Separating and flanking walls constructed with the Celcon
Thin-Joint System satisfy the sound insulation requirements of the National Building
Regulations allowing the building to benefit from the construction speed of the Celcon
Thin-Joint System whilst retaining an homogeneous build system. For further details see
Celcon’s Guide to Part E Sound Insulation Regulations or contact our Technical Services
Department for detailed advice on constructions meeting the requirements for separating and
flanking walls.
Foundations Celfix Mortar is suitable for use in classes DS1 and DS2 soil and
groundwater conditions as defined in Table 2 of BRE Special Digest 1 - Concrete in aggressive
ground Part 1:2001.
Extensions Whether the wall is solid or cavity construction, the Celcon Thin-Joint System
is ideal when building extensions. The inherent speed of build enables quicker construction
times, excellent thermal efficiency meeting today’s thermal requirements, reduced wastage of
blocks and mortar and a potentially cleaner site.

components...
Produced with the latest manufacturing technology at H+H Celcon’s
plant in Yorkshire, Plus and Jumbo Plus blocks benefit from sharp
clear arrises and excellent dimensional tolerances making them ideal
for use with the Celcon Thin-Joint System. They are produced with a
plain face and are supplied nationwide with any Celfix Mortar order.
The key to the Celcon Thin-Joint System is Celfix Mortar,
designed specifically for use with Celcon blocks. It is supplied
dry and pre-mixed in 25kg bags, and should be added to water
(approx. 4.5 litres per bag, for yield see page 12) and mixed
until a thick smooth consistency is achieved, as instructed on
the pack. Applied with either a ‘scoop’ or ‘sledge’ to maintain a
consistent joint thickness of 2mm, it remains workable within
the bucket for a number of hours, but reaches initial bond
strength on the block within 10-20 minutes and full design
bond strength within 1-2 hours.
Celcon Plus blocks - Face size 610mm x 140mm
Produced in thicknesses from 200mm upwards, they are designed for
solid wall and foundation construction, meeting the CONIAC limit of
20kg for repetitive lifting, and are manufactured in Solar, Standard and
Hi-Strength grades.
Celcon Plus blocks - Face size 610mm x 215mm
The Plus blocks are produced in various thicknesses. They are suitable
for the construction of solid and cavity wall types and manufactured in
Solar, Standard and Hi-Strength grades.
Celcon Jumbo Plus blocks - Face size 610mm x 270mm
The Jumbo Plus block is produced in various thicknesses. They are
suitable for the construction of cavity wall types, manufactured in Solar,
Standard and Hi-Strength grades. These larger format blocks can increase
the speed of construction whilst improving the thermal performance of
the building by reducing cold bridging through the mortar.

Installation
a step by step guide
Building with the Celcon Thin-Joint System is a fast and
simple process. The greatest benefits are achieved where
the blockwork inner leaf is constructed first, creating a
weather tight environment for follow on trades to work in.
With the brickwork taken off the critical path, it can be
constructed within the remaining build programme, using
several types of widely available wall ties produced for use
with Thin-Joint Systems, see page 16.

1 To gain the maximum benefit from the
Celcon Thin-Joint System, it is necessary to
adapt the schedule of materials and services supplied to
the site, e.g. the blockwork should reach first floor level
in 1-2 days, therefore scaffolding needs to be in place
before starting the build. Lintels and floor joists will need
to be on site during this period.
The first course of blocks should be bedded normally using
a conventional designation (iii) mortar. Conventional mortar
is required to accommodate any irregularities in the
supporting structure. This base course can use Celfix Mortar
if the System has been used in the foundations or the slab
is sufficiently flat.
It is essential that the blocks are laid accurately, true to level
(±1mm) and vertical (many builders use a simple laser level for
speed and accuracy). The perpend joints on the first course can
be of Celfix Mortar giving a more rigid base in a shorter time.
Should any irregularities or imperfections occur on the bed
course, surfaces should be sanded down using a proprietary
sanding board. Jointing faces should be clean and free from
dust, if necessary, cleaned using a stiff brush.
4

8 Provided the initial stages are followed,
the quality and speed of the Celcon
Thin-Joint System allows continual building, with no
need to wait for mortar to set. With the brickwork
taken off the critical path this allows the first lift
to be easily achievable in one day and building to
roof plate within 2-3 days.
Blocks can be cut with traditional hand tools,
such as a hand saw and a cutting square.
However, builders have found it more efficient
on larger sites to use mechanical tools such as
electric hand saws or circular saws.
Wall ties are available for cavity wall
construction, enabling the greatest
benefits to be achieved by building
6
the inner leaf first.
Supplied dry and pre-mixed in bags, Celfix Mortar should
be added to water (full guidance is given on the bag) in
a clean bucket. Mixing using a power tool with whisk
attachment set at a low speed, achieves the thick smooth
consistency required. Celfix is workable for several hours
whilst in the bucket. Celfix Mortar should be applied
using either a scoop, available in sizes from 75–200mm,
or by using sledges, available in sizes from 200-300mm.
Both of which will provide a consistent joint thickness of
2mm. As laying proceeds, blocks should be pressed
firmly against the mortared vertical face whilst lowered
onto the mortared bed below, ensuring that the joints
are fully filled.

FIRE RESISTANCE
Structural design
Fire resistance
The Celcon Thin-Joint System should be used following the general
recommendations of BS 8000 Part 3:2001 and BS 5628-3:2001 and
BBA certificate 01/3816. In addition, Celcon’s ‘Book of Blocks’
contains advice on general site practice. The inherent properties of
aircrete applies equally to thin-joint masonry.
Walls constructed using the Celcon Thin-Joint System can be designed in accordance
with the structural Eurocode for masonry ENV1996.1.1. Better values of masonry
compressive strength are achieved with Celfix Mortar when compared to general purpose
mortar. It is also possible to design to BS 5628-1:1992 assuming a characteristic
compressive strength of Celcon thin-joint masonry based on Table 2 values given for
designation (i) mortars.
The characteristic flexural strengths of Celcon thin-joint walls can be taken to have the
same values as those for designation (i) mortars in BS 5628-1:1992 Table 3.
Celcon blocks have excellent resistance to fire. Extensive use has proved their
capability in fire-break walls and as protective cladding for other forms of construction,
for example steel frames.
Celcon blocks are classified as non-combustible and have a class 0 surface spread of
flame as described in the National Building Regulations.
The figures given in the table below have been derived from Eurocode 6:
Design of Masonry Structures:Part 1-2. General rules – Structural fire design (DD ENV
1996-1-2:1997) together with the UK National Application Document.
If Celcon blocks are to be used in cavity wall constructions, either in new build or
renovation work, the thickness shown below may be reduced; contact the Technical
Services Department for further advice.

Sound insulation
Thermal insulation
Sound insulation of any masonry construction depends on the
density and porosity of the material used. The structure of
aircrete, consisting of a vast number of tiny, noninterconnecting
air cells, gives high resistance to airborne sound.
This considerably improves on the normally accepted mass law
relationship applied to other types of masonry materials.
Celcon’s products have excellent sound insulation qualities,
which can easily achieve the requirements for internal and
separating (party) walls and floors as well as flanking elements
of the new Part E of the Building Regulations. The use of Celfix
Mortar provides the added benefits of further improvements in
sound insulation as well as faster speed of build.
For further information regarding sound insulation please
contact our Marketing department and request a copy of our
Celcon Solutions to Part E brochure. An example of a separating
(Party) wall solution is shown above.
Given the excellent thermal properties inherent with Celcon aircrete
blocks, the Celcon Thin-Joint System can offer enhanced benefits.
Approved Document ‘L1 & 2’ of the Building Regulations requires that
heat loss through mortar joints be taken into consideration when
calculating U-values for walls. The use of Celcon thin-joint blockwork
minimises these effects by reducing the relative area of mortar per m2 of wall. The actual performance of the wall, with regard to heat loss,
will actually be better than similar walls built using traditional
mortar with normal format blocks. For example in a solid wall
solution an improvement of up to 20% in U-value can be achieved.

Cutting blocks
Cavity insulation
Scaffolding systems
Generally it is not possible to use a conventional
putlog tied scaffold where the inner leaf
blockwork is built ahead of the outer leaf. The
most versatile and cost effective solution is to use
a proprietary system scaffold to build an
‘independent’ scaffold. Systems such as Kwikstage
or Cuplok are readily available throughout the UK.
It is also advisable to make sure that the setting
out of the scaffolding takes into account the outer
leaf being built at a later date.
There are a number of ways that Celcon blocks can be cut. The traditional method is to
use a hand saw. However, depending on the size of the project, builders have found it
more efficient to use mechanical tools such as electric hand saws, circular saws and
band saws, particularly when cutting the larger blocks.
To maximise the productivity advantage of the Celcon Thin-Joint
System the inner leaf can be built first. In addition to achieving an
immediate weathertight structure, this also allows for easy inspection
of the cavity side of the blockwork and permits the use of partial fill
or full fill insulation. Since the inner leaf blockwork is free of wall
ties and mortar snots, insulation boards can be placed up against the
blockwork with helical type wall ties driven through the insulation
into the blockwork behind. Because the insulation boards are fixed by
mechanical ties, they cannot become loose during construction. Thus
the risk of rain penetration is significantly reduced.

Wall junctions
Walls should normally be bonded in at returns and
junctions unless a movement joint is required.
Where a section of wall has to be constructed after other work,
bonding can be replaced by a straight joint, providing proprietary flat
strip shear ties are built in across the joint (as shown) or helical ties driven in during
construction. This method of jointing is preferable to bonding under circumstances where
differential movement is likely to occur (e.g. where sections of wall are built off different
foundations). Where an inner leaf is built prior to the outer leaf, helical ties can be
driven through the inner leaf into the internal partition (penetration into the partition
should be a minimum of 50mm). These ties can be positioned irrespective of coursing.
Where enhanced sound insulation is required, an acoustic sealant can be applied to each
side of the vertical straight joint.
3M 3
Movement joints
As for all masonry walls, the accommodation of movement should be
considered at the design stage. The following general recommendations
apply to aircrete:
- Walls in excess of 6m long should be designed as a series
of panels separated by movement joints at not more than
6m centres
- The position of the first joint from the corner should be
designed to be within 3m of a corner or fixed end
- An alternative to movement joints is the use of bed-joint
reinforcement, where entire wall panels are reinforced.
This alternative is recommended particularly for an
externally rendered solid wall construction or an outer
leaf of rendered blockwork. This also applies to separating
walls which should not contain movement joints
6M

Construction of movement joints
Straight, unbonded vertical joints are the most common
form of movement joint. They can be formed by butting
the Celcon blocks against each other as a dry joint, or
by leaving a 10mm gap filled with fibreboard.
Bed joint reinforcement
Movement joints should normally be continued through all surface
finishes using stop beads (at one or both edges of the joint) to end
the finish. Alternatively, a proprietary type of cover strip or an
architrave pinned to one edge of the joint can be used.
Where lateral stability demands continuity across the joint, propriety
flat strip shear ties should be set in at 450mm maximum vertical
centres. These should be set parallel to the plane of the wall,
allowing the plain end to become de-bonded if movement occurs
within the blockwork panel, thus creating a movement joint.
For areas of high stress (e.g. at openings or where the blocks are under concentrated
imposed loads) horizontal bed-joint reinforcement is recommended. It should be of
adequate length to distribute stresses to nearby movement joints or into adjacent
areas of blockwork. For example, it should extend at least 600mm into the adjacent
blockwork each side of an opening. Reinforcement should normally have a mortar cover
of a minimum of 13mm to internal faces of blockwork and 25mm to external faces.
Entire wall panels may be reinforced so that movement joints which would otherwise be
advisable can be omitted. Where a wall is supported by a floor which is itself subject to
deflection, the first two courses of the wall should be reinforced.
Only bed-joint reinforcement which has been specifically
manufactured for use with thin layer mortar masonry should be used
with the Celcon Thin-Joint System.
Movement joints and bed-joint reinforcement around openings are not
normally required for housing where independent finishes are being
used, i.e. dry lining, weather boarding, tiles on battens etc. Our
Technical Services Department will be pleased to give
recommendations for specific projects.
For further information on movement joints please see page 21
for contact details.

Lintels
Wall ties
Detailing around windows
When forming window openings, the blockwork can be taken up in full block
heights and then cut blocks used to build up to sill level and lintel heights.
Alternatively, whole blocks can be cut to allow the lintel to fit. Reveals can
be formed by cutting the required block thickness to suit the reveal,
applying the Celfix Mortar and then placing into position. Nailing may be
required to temporarily support the first reveal block. Subsequent blocks can
then be built above this as work proceeds.
When using Celcon’s Thin-Joint System there are several types of lintels
available, the most common of which are concrete, steel box and combined
(or ‘top hat’) lintels.
For cavity walls, whether they are of block/block or brick/block
construction, the box lintel is recommended. If using a combined lintel,
propping will be required until the outer skin is brought up to support the
lintel and prevent it rotating.
For solid wall constructions H+H Celcon recommend the combined type lintel
with a 100mm block either side at lintel level.
Bedding lintels on a traditional sand/cement mortar bed allows them to be
more easily and accurately positioned.
Being at the forefront of innovation H+H Celcon is currently developing
reinforced aircrete lintels for use with solid wall construction techniques. These
lintels will offer the benefits of speed of installation, the continuation of surface
for finishing and remove any concerns regarding thermal bridging.
There are several types of wall ties suitable for thin layer mortar masonry. Generally the
most effective are helical type ties that can be driven into the face of the blockwork at a
level which will course with the outer leaf mortar joint. Insulation can be placed against
the inner leaf before wall ties are inserted. Helical type ties (as
manufactured by Helifix) can also incorporate clips for partial fill insulation
and are positioned as the outer leaf proceeds, thus minimising the risk of
injury from projecting metal and reducing the build up of mortar snots. Ties
are also available which may be laid in the thin-joint beds as block laying
proceeds. This is particularly appropriate where both leaves are built
together. All ties should conform to BS 1243, British Standard Draft for
Development 140:Part 2, or a BBA Certificate. It is recommended that ties
are not driven in to the wall until it is restrained at the head by the timber
joists/flooring system.
For further information on wall ties please see page 21 for contact details.

Stability
Temporary propping of walls always needs to be considered at the design
stage (see for example BS5628 Part 1, clause 20.4). It may be necessary for
a number of reasons – in particular due to site or weather conditions.
With housing, internal partition walls and partially completed external walls
can be vulnerable when they are subject to temporary loadings, the most
common of which is the moving of plant and/or materials, or in exposed
conditions, wind load.
Finishes
One of the benefits of the Celcon Thin-Joint System is that, due to the greater accuracy,
alternative finishes may be considered, in particular thin coat sprayed systems.
Spray finish - plaster or render
Applied direct to blockwork with a total thickness of 3-4mm, the use of spray
plaster/render can greatly reduce the time taken to apply an internal/external
finish, it therefore complements the inherent speed of the Celcon Thin-Joint
System.
Internal tiling
Tiles can be bonded direct to blockwork provided surfaces are dry or almost
dry and are free from dust, oil and other forms of contamination. Tiling
should be fixed with a proprietary adhesive, using the solid-bed technique.

6 Frequently Asked Questions
20
What Certification has been given to the System?
The Celcon Thin-joint System is approved by the BBA (see certificate No. 01/3816), NHBC and
Building Control.
Are you sure that you can build the inner leaf first without bringing the outer leaf
up at the same time?
The BBA has approved this as "normally permissible to build the inner leaf to storey height ahead of the
outer leaf". Like all masonry walls, depending on the lengths of walls involved and on the weather and
exposure conditions, temporary propping may be required.
Is coursing with brickwork an issue with the thin-joint? What sort of tie can I use?
No, because ties can be installed by driving into the face of the blockwork at a level which will course
with the outer leaf. Several types of driven ties are available for the purpose, such as helical ties.
Is there any quality improvement in the construction?
Potential is high for quality improvement, including cleanliness of the site and reduced wastage of
blocks and mortar as well as the build quality of the construction.
Where can we get the thin-joint tools from?
The hand tools used with the Celcon Thin-Joint System, such as scoop and cutting square, are available
from builders’ merchants, contact details are available through our Sales office on 01732 886444. For
specialist equipment such as circular saw, please see list at the back of the brochure.
Who uses the Celcon Thin-Joint System?
Builders throughout the industry from sole traders to the National housebuilders use the Celcon Thin-
Joint System for the construction of extensions through to complete sites. It is used in domestic as well
as commercial/industrial work and has the potential for improving both productivity and quality of
construction benefits.
It has been found that attitude counts for a lot, if the builders want to make it work, it will and it
does. Some have given it the ‘thumbs down’ but in contrast others have said they would now not want
to go back to traditional unless they had to!
Is training available for the Celcon Thin-Joint System?
Thin-joint training is available at various levels from demonstrations at builders’ merchants and colleges
to instruction on site start-ups. Contact the Technical Services Department on 01732 880580 to find out more
details. Please note that our instructors are only on site to demonstrate. They are unable to build for you.
What are the setting times of Celfix once mixed with water?
Celfix remains workable in the bucket for several hours. However, after being applied to the block it
takes 10 minutes for initial set and 1-2 hours for full design strength to be achieved.
How do I get over the issues of coursing with lintels?
Whatever the masonry, opening sizes and course heights have to be worked out prior to building.
Unlike traditional masonry, any irregular course height can be simply achieved, as Celcon blocks are so
easy to cut.
What is the workability of the System in the following conditions?
...in cold weather? Unlike traditional mortar, Celfix can be used down to 0 o C but the blockwork MUST be
considered in relationship to the overall site operation. See BRE Defect Action Sheet (Site) DAS 64 (‘bad
weather working’) which provides good practice guidance for masonry.
...in wet weather? Work should have same protection as other types of masonry BUT as Celfix sets
more quickly than traditional mortar, there is less risk of joints being washed out!
...effect of block suction? Will depend on weather conditions. Adjust to suit.
