Sure Seal of NE’s spray foam insulation is an energy-efficient polyurethane foam insulation that is sprayed onto surfaces to create a seamless barrier against air, moisture, and heat transfer. It is made by mixing two separate chemicals, polyol resin and isocyanate, which react to form a foam that expands and hardens quickly. This innovative and versatile material is the perfect insulation seal for builders, architects, and homeowners looking to save money on energy bills, improve indoor comfort, and protect their homes from the elements.
