What is Spray Foam Insulation?

Spray Foam or Spray Polyurethane Foam (SPF) is created using two separate chemical compounds which are heated then sprayed simultaneously through specialized equipment. The proper heating and mixture of the chemicals results in a reaction that creates foam insulation. The liquid mixture is sprayed to the surface to be insulated, then rapidly expands and cures in seconds to form a solid, seamless air barrier, and superior insulation material.

Spray foam is the ideal method for insulating commercial and residential buildings because it allows custom fitting to any architectural design or construction material. Spray foam stops air and moisture intrusion, greatly reduces energy bills, strengthens the building structure, and protects the internal air from mold, airborne pollutants, and allergens thereby creating efficient healthier buildings.
