Building Envelope Materials is on a mission to develop quick inexpensive minimally disruptive methods to reduce the thermal energy use of existing buildings to zero.

Our mission began in 2014 when we were awarded a grant by the Massachusetts Clean Energy Center (MassCEC) to develop a way to inject highly insulating closed cell polyurethane foam into  "under-insulated" fiberglass filled wall cavities. Since then, we have further developed and refined the technology through additional grants from the MassCEC, the US Department of Energy and CertainTeed/Saint Gobain.

The results have been phenomenal. We can fill an entire wall cavity through one easily patched 1/2" hole and can inject an entire house in just one day. In a typical 1950's era fiberglass insulated wall, our technology increases insulation values from R10 to R23 and has been demonstrated to reduce energy usage by 25% or more.

We're currently expanding our injection technology to cathedral ceilings, dormer roofs and flat roofs. We're also developing safer alternatives to traditional spray foam for use in new construction, roof rafters and other open cavity applications.

When fully deployed in all the cavities of a typical building, our injection technology will double or triple the energy savings of traditional weatherization technologies.

We are grateful for huge support from the following organizations:
