Icynene Spray foam

Icynene Licensed Contractor for spray foam insulation
Weatherseal have selected Icynene as it is the world leader for quality and it is the only spray foam certified in Ireland. In other words, it is ideal for direct application to breathable and non-breathable membranes. This is due to its very low moisture absorption.
Icynene is the cleanest and greenest spray foam insulation on the market due to the fact that it is 100% water blown.  Also, it does not contain the nasty catalyst BL-19 and is the foam of choice for the American Lung Association
