The Icynene Insulation System which is 26 successful years on the market worldwide, is a soft, flexible spray foam insulation that gives up to 50% greater energy savings when compared to other insulation products. When sprayed in place Icynene expands completely filling all cavities and voids creating a sealed building envelope which eliminates air leakage/infiltration. Air leakage/infiltration accounts for up to 50% of heat loss from a building. Unlike other bio based and urethane foams, Icynene is 100% water blown and therefore contains no harmful agents, volatile organic chemicals, HCFCs, HFAs, HFCs or formaldehyde.Icynene is the only foam on the market sucessfully tested and certified for applications directly to the underside of breathable and non breathable roof membranes and felts and recently received BBA certification for this application.Icynene absorbs the lowest amount of moisture and has the highest level of vapour resitivity of any soft foam on the market. Icynene is suitable for attic applications on the horizontal and slope and is also suitable for walls and floors, in addition to excellent insulation and air tightness values Icynene also provides excellent noise reduction properties
