spray foam

Spray polyurethane foam aka (Spray Foam Insulation) is a heat-activated polymer that is just what it sounds like, a foam insulation that is sprayed into place. It is made by mixing two ingredients, A Component – Iso and  B Component – Resin onsite using special equipment most commonly by Graco. The mixture is then pumped through a heated hose, then sprayed using a gun onto the surface that needs to be insulated. While the chemical reaction between the two ingredients takes place the liquid turns foamy, expands and then instantly hardens in place.
