Product Description
Spray-foam insulation has been criticized for the release of toxins during installation, but the product’s manufacturers are beginning to respond with environmentally friendly alternatives. Among them is Canadian spray-foam maker Icynene, which developed ProSeal Eco, a 100-percent water-blown closed-cell foam that doesn't contain greenhouse-gas-emitting blowing agents and offers an R-value of 4.9 per inch of thickness.
