Building Envelope Materials' Pinhole Insulation is a minimally invasive retrofit insulation system for large multifamily buildings. The system works by injecting closed cell polyurethane foam through a 1/4" hole, allowing for envelope upgrades in a matter of hours and without resident relocation. Once the material is injected, it more than doubles the R-value of any existing wall and completely stops any cold air movement within the wall cavity — reducing thermal energy use by 20 to 30%.

• Upgrade building envelope

• Insulate building/unit

• Reduce cold air infiltration

• Regulate indoor temperature

• Reduce building energy/utility costs

• Minimally-disruptive, quick installation - Pinhole Insulation can be installed in 2-3 hours per apartment, without relocating tenants

• Compatible across building typologies - It can be installed in virtually any size or type of building, including large masonry exterior buildings that would not be accessible to dense-pack cellulose

• Non-hazardous, fire-safe - Pinhole Insulation delivers on air quality safety (no hazardous particulates generated) and fire safety (Class 1 fire rated material)

• Low Global Warming Potential - The foam has a global warming potential over 1,000 times lower than older convential polyurethane insulating foams

Third party case studies indicate a 20-30% thermal energy reduction resulting in a 10-15% reduction in utility bills
