Closed Cell Spray foam Insulation

Polyurethane Insulation

Closed cell spray foam is an insulation material that is sprayed onto surfaces in liquid form, then expands and hardens into a dense, airtight foam. It offers superior insulation performance compared to other materials, with an R-value of R1.0 per 20mm thickness, making it a top choice for building envelopes. Its air sealing capabilities also make it an effective moisture barrier, preventing mold and mildew growth. Closed cell spray foam is a sustainable option for those seeking to reduce their carbon footprint, as it can significantly lower energy consumption and heating and cooling costs.
