SPF (Spray Polyurethane Foam) is an insulation and sealant that forms into a tight continuous barrier on surfaces around the home such as walls, roofs, and corners. Spray polyurethane foam offers a highly effective solution in eliminating unwanted cracks and holes where air can seep through. SPF is created on the job site by mixing two liquids (isocyanate and polyol resin) together. These two liquids mixed together can expand between 30-60 times its size after sprayed.
UFFI (Urea Formaldehyde Foam Insulation), often referred to as Amino Foam, is an insulation that can be mixed together at the jobsite; however, it is not a polyurethane foam. UFFI is created by mixing urea-formaldehyde and compressed air. Urea Formaldehyde Foam Insulation is pumped through holes drilled in interior and exterior walls. UFFI was popular in the 70’s, but is now overshadowed by Spray Polyurethane Foam.
