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. Their mission began in 2014 when they 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, they have further developed and refined their pinhole insulation technology through additional grants from the MassCEC, the US Department of Energy and CertainTeed/Saint Gobain. The results have been phenomenal. They can fill an entire wall cavity through one easily patched 1/2” hole and can insulate an entire house in just one day. In a typical 1950's era fiberglass insulated wall, their technology increases insulation values from R10 to R23 and has been demonstrated to reduce energy usage by 25% or more. They're currently expanding their pinhole insulation technology to cathedral ceilings, dormer roofs and flat roofs. THey'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, pinhole insulation will double or triple the energy savings of traditional weatherization technologies.
