Polyurethane Spray Foam is the solution for all your insulation needs. It is a seamless, “spray-in-place” insulation that is low density, rigid, closed-cell, foam. It has the most efficient insulating properties available. We are certified applicators and our foams have CodeMark certification.
It comprises of a 90% closed cell formation, thus drastically reducing the chances of water absorption or transmission. Polyurethane has tremendous thermal properties. Our closed cell foam has an R value of 1.18K·m2/W per 25mm making it the most efficient insulation for residential housing . We prefer to use only closed-cell foam as it has the highest R-value, lowest permeability for water vapour transmission, and adds structural integrity as well as soundproofing. Not all spray foams provide these benefits.
We can also offer open cell foam which has an R value of 0.78K·m2/W per 25mm.
Open cell Foam has a lower density than Closed cell foam and requires a thicker application to achieve the equivalent "R Value". The cost works out similar to closed cell for a given "R Value" . It has better noise insulation properties than closed cell foam. The open cell foams rise to 80-120x their liquid volume which makes them ideal for sealing up cracks and crevices to provide excellent insulation coverage. Open cell foam will insulate and air seal but may allow water vapour to migrate through it over time.
Please contact us to discuss your insulation requirements and select the appropriate foam for your application.
