A green alternative to chemically based spray-foam insulation, this product is water-blown.

As a sustainable alternative to chemically based, medium-density closed-cell spray foams, spray-foam insulation manufacturer Icynene’s 100% water-blown product lets architects and designers capitalize on the use of closed-cell spray foam as a sustainable insulation option for residential and commercial projects. ProSeal Eco offers an R-value of 4.9 per inch of thickness and serves as a class II vapor retarder at 2.4”. The product semi-impermeable at a PERM rating of 0.1 perms to 1.0 perms. The medium-density insulation contains no synthetic blowing agents, which emit greenhouse gases. It can be used with a range of substrates and in a variety of climates. icynene.com
