Making good on the “right place, right time” ethos, The Green Cocoon was launched in 2007 by plastics engineer Jim Materkowski and his business partner, the late Peter Strattner, both of whom saw in the ever-growing green insulation industry room for a company committed to more options. In the years since, the company has grown to include a wide range of green insulation options including spray-foam made from soy beans and recycled plastic bottles, BATT insulation made from recycled denim, as well as a line of cellulose insulation made from recycled newspapers.

Not only does spray foam remain the top green option on the insulation market; it also boasts a host of residual benefits – offering air and vapor barriers and hurricane-grade strength that helps make it the ideal option for coastal-lying buildings. Indeed, all of Green Cocoon’s options boast their own unique qualities – qualities that meet the highest standards of durability and green quality.

Green insulation has exploded over the past few years thanks to a growing recognition that the up-front cost – itself getting more and more competitive all the time – is more than made up for in down the road savings. With that green calculus squarely in mind, Green Cocoon has grown to become a go-to resource in Northern New England, and a sustainability success story to boot.
