A New Halogen-Free Polyiso Insulation from GAF
GAF now offers a full line of polyisocyanurate foam insulation that is free of toxic halogenated flame retardants.
by Alex Wilson
I first learned about GAF’s new halogen-free polyisocyanurate insulation when I was teaching a workshop on resilient design at the GAF headquarters in Parsippany, New Jersey, in March, 2017. Having called for manufacturers to develop such products several years ago (see Getting Flame Retardants Out of Foam Insulation), I am particularly attuned to such developments.
It so happened that I was also looking for rigid insulation material to insulate the roof of a small cottage in Brattleboro, Vermont. I had thought of polyiso for this application, because of the high R-value. Here was a chance to install a product I could feel good about relative to chemical ingredients as well as energy performance. I reached out to GAF, and we ordered the product. (Disclaimer: GAF provided me with a discount on the material and covered the shipping cost.)
