Icynene is said to be a high-performance, spray-foam insulation that expands 100-fold when applied, sealing all gaps, service holes and hard-to-reach spaces where air leakage can occur. It eliminates cold bridging and achieves air tightness standards in excess of those required for Passivhaus-type construction.
Air leakage is said to account for a high proportion of the heat loss from a building and often has a greater impact on the thermal performance than thermal conductivity through walls and roof planes.
Icynene says it has an open cell structure and soft, yielding texture. According to the company, this not only provides outstanding insulation properties, but also allows the building to breath naturally – resisting internal condensation which is particularly important when insulating heritage-type buildings.
Icynene reportedly achieves insulation performance well in excess of the U-values required under Building Regulations and helps meet the sustainability and zero carbon targets faced by housebuilders.
