Founded in 2014 and based in Amesbury, Massachusetts, Building Envelope Materials focuses on developing innovative, cost-effective methods to drastically reduce the thermal energy use of existing buildings. Their core mission is to achieve zero thermal energy use through minimally disruptive insulation technologies. The company offers Pinhole Insulation®, a unique retrofit insulation solution designed for large commercial, institutional, and multifamily buildings where traditional methods are impractical or ineffective.

Building Envelope Materials received initial funding from the Massachusetts Clean Energy Center (MassCEC), which enabled them to develop their pioneering closed-cell polyurethane foam injection technology. The company has since refined this technology and applied it to various projects, including affordable housing and passive house rescues. Their work has significantly impacted energy efficiency in building retrofits, contributing to sustainability and cost savings in the built environment.
