Not All Insulation Is Created Equal

Demilec USA spray foam seals cracks, gaps, and voids by expanding to air seal and insulate in a single application. The combination of the expanding foram and the inherent adhesive properties of the polyurethane plastic sets our insulation apart from others.

High air permeability of traditional insulation allows air to easily pass through walls where gaps and seams exist. Also, differences between interior and exterior temperatures create convective air currents within wall cavities. Air infiltration and convection currents in walls and ceilings reduce the thermal performance of traditional insulation.

Just wanted to express our thanks for the wonderful work that you did on the addition to our home. The work was done timely, on budget, and of high quality. Further from our first meeting with you, we knew that we were dealing with a company that was going to treat our project like it was for a close family member.
