G.M.S Insulations Ltd.

Having over 30 years experience each in the construction industry, Paddy Leighton and Gerry Sheridan set up Greentherm Solutions Ltd to distribute and market the Icynene® range of Spray Foam Insulation products to the UK market. They identified a gap in the market for an insulation product that would provide high levels of insulation combined with air tightness in one application. Conventional insulations were not capable of doing this and had a detrimental effect on good construction practices and energy efficiency measures.


Icynene® Spray Foam Insulation Products
The Icynene® Insulation System is a series of soft, flexible spray foam insulation products that delivers up to 50% greater energy savings when compared to other insulation products. Icynene® is perfect for loft insulation, cavity wall insulation, drylining insulation, sound insulation and more.

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 foams, Icynene®’s unique polyicynene formulation 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 successfully 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 resistivity of any soft foam on the market.
