SPRAY FOAM INSULATION
ICYNENE TRAINED AND ACCREDITED INSTALLERS
Low thermal conductivity: provides good thermal performance in new and existing structures.
Non-irritant and hygienic: unlike many other spray foam insulations Icynene is totally inert, odorless and produces no harmful emissions after installation.
Air-tight: it expands in volume by up to 100 times after spraying, pushing its way into cracks and voids to form a complete seal to surfaces and cavities.
Vapour open: the open cell structure allows water vapour to diffuse through the foam, preventing harmful build up of moisture within a structure.
A good acoustic insulant: ideal for reducing sound transmission into and around buildings.
Does not sag: unlike other flexible insulants – such as mineral fibre and cellulose – which slump and sag over time, Icynene retains its shape, giving long term thermal performance.
Icynene open cell foam is a water-blown, two-part foam, consisting of a polyol resin and MDI catalyst. It is available in three types, each suited to a different range of applications.
• Icynene LD-C-50(H foamlite): rapidly expanding foam intended for spraying onto surfaces and used for insulating walls, roofs and floors.
• Icynene LD-C-70 (H2 foam lite plus): rapidly expanding foam intended for spraying onto surfaces and used where higher foam density is required.
• Icynene LD-P-50: contains less catalyst than LD-C-50, producing a slow rise foam which is ideal for filling cavities, particularly in sensitive structures.
Structural: Icynene foam is self supporting and does not slump or sag. It is sufficiently flexible to allow differential movement of the materials to which it is bonded without delaminating from the surface.
Chemical: Icynene foam can be sprayed directly onto zinc without causing corrosion. It is compatible with most common chemicals occurring in construction.
Fire: Like most other foams Icynene foam is combustible and must be protected from naked flames and ignition sources.
When Icynene foam is installed in a timber structure behind 12mm plasterboard the structure achieves a fire rating of B-s1, d0.
Icynene does not propagate flame and does not drip. It is self-extinguishing.
Air: Icynene spray foam is airtight and forms an effective air barrier.
Biological: Icynene does not support the growth of mould or fungus and is not a food source for rodents or insects.
Durability: Icynene spray foam can be expected to last for the life time of the building.
Environmental: Icynene spray foam does not contain any chemical blowing agents, HFCs or PBDEs. It has a Global Warming Potential (GWP) of 1 and an Ozone Depletion Potential (ODP) of 0.
Water: Icynene spray foam will not ‘wick’ water, but it is not a waterproofing measure and will not prevent the passage of liquid water. If wetted, Icynene foam retains it shape, without shrinking or distorting, and regains its performance when dry. Icynene foam is vapour open and does not prevent the passage of water vapour.
To tell if an air source heat pump is right for you, there are a few key questions to consider:
Do you have somewhere to put it?
You’ll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air. A sunny wall is ideal.
Is your home well insulated?
Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s essential that your home is well insulated and draught-proofed for the heating system to be most efficient.
What fuel will you be replacing?
The system will pay for itself much more quickly if it’s replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.
What type of heating system will you use?
Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.
Is the system intended for a new development?
Combining the installation with other building work can reduce the cost of installing the system.
An air-to-air system produces warm air which is circulated by fans to heat your home. They are unlikely to provide you with hot water as well.
An air-to-water system distributes heat via your wet central heating system. Heat pumps work much more efficiently at a lower temperature than a standard boiler system would. This makes them more suitable for underfloor heating systems or larger radiators, which give out heat at lower temperatures over longer periods of time.

Masonry Crème is an invisible insulation barrier.
A surface treated with ProPERLA Masonry Crème will insulate mineral building materials by reducing water absorption. The product chemically bonds to the surface, penetrating up to 17mm to create an invisible insulation barrier.
It means water cannot stick to the coated surface but forms droplets that run off the surface.
Tests have shown that a damp content of 5% in a plain brick wall, for example, can lower the insulation performance by up to 50%, especially where cavity wall insulation has been installed. Porous building materials, such as natural stone and brick normally have good insulating properties as they have air filled cavities, which offer low thermal conductivity, but only when they are dry.
Icynene foam is well-suited for insulating walls and roofs in new buildings; it provides a high standard of thermal insulation, minimises air leakage and reduces the transmission of contaminants from outside, as well as reducing nuisance noise. Icynene foam forms a permanent, seal to studs, flexing and moving with the rest of the construction, so improving the long-term airtightness of the building and reducing energy use.
Timber or steel frame walls may be insulated by spraying Icynene foam between the studs, to their full depth, while walls of portal frame builds may be insulated by filling the cavities between the internal and external faces with Icynene foam.
Roofs may be insulated by spraying to the underside of the deck (flat roofs), timber sarking, or to the underside of the roofing membrane. Because Icynene foam expands when sprayed it is easy to form a continuous layer of insulation even across challenging roof shapes.
Icynene may also be sprayed to the underside of metal roof decks to minimise rain noise.
Icynene can be used to upgrade existing masonry walls by internally insulating them. The internal face should be battened out to the required depth with battens at 600mm centres. Icynene is then sprayed to the depth of the battens and trimmed. The wall is then finished with plasterboard.
As insulating the inner face will change the temperature profile through the wall, condensation risk analysis should be carried out to determine whether a vapour control layer (VCL) will be required.
System built walls, such as Trusteel, can be insulated with Icynene LD-P-50 in the wall cavity. Similarly, cavities behind lath and plaster on solid stone walls can also be insulated with Icynene LD-P-50.
Suspended timber floors suffer from heat loss by conduction to the underfloor void, while sub-floor ventilation to prevent damp results in draughts between the boards and at the floor perimeter.
Icynene foam can be sprayed to the underside of the boards, filling the space between the joists. The insulation will reduce conduction heat loss through the floor – making it warmer underfoot – and also eliminate air infiltration through the deck and the perimeter.
The installation should leave a minimum 150mm air gap between the underside of the joists and the surface of the sub- floor void. High-rated electrical cables (such as cooker or shower supplies) should be de-rated or set in trunking or conduit to avoid overheating.
Icynene foam can be sprayed on the underside of tiles and slates and timber sarking to upgrade the thermal performance of existing pitched roofs (figure 06). The loft may be insulated in order to improve the overall thermal performance of the dwelling, or to provide additional living space. Where a low U- value is required it may be necessary to fix cross battens to the underside of the rafters to increase the depth of Icynene foam.
The gable walls should also be insulated with Icynene spray foam to form a well conditioned space. If the loft is going to be used as an occupied space the Icynene foam must be protected with a fire-resistant covering such as 12.5mm plasterboard.
Icynene foam may be sprayed onto the underside of a vapour open roofing underlay. The foam maintains the drape of the underlay, allowing wind-driven rain to drain from the batten space without the need for counter battens.
Where the roofing underlay has a high vapour resistance (being either bituminous felt or polyethylene) condensation risk analysis must be carried out to test for a risk of interstitial condensation. Where there is a risk of condensation a vapour control layer should be installed to the underside of the roof, immediately above.
Single or twin-skin metal sheet roofs may also be upgraded with Icynene foam to reduce air leakage, minimise sound transmission and avoid condensation forming on the underside of the roof.
