The Benefits of Spray Foam Insulation
There are several advantages to using spray foam over other types of insulation.

Our clients often ask us how spray foam works. Good question. Engineers create spray foam by combining two materials, isocyanate and polyol resin, into a reactive mixture called polyurethane. When these two elements come together, a hot foam is produced that expands once it’s sprayed. There is a powerful adhesive element to spray foam that makes it stick to any surface – woods, metal, drywall, stone, etc. The polyurethane will continue to expand until it has reached its limit or it has filled an area to capacity.
Spray insulation provides a waterproof barrio that can keep mold and mildew from settling into the frame of your house, since it does not hold on to moisture like fiberglass insulation. Additionally, spray foam insulation is not edible, so you will not be finding little rodents making their home in your walls or even eating your insulation.
Like water, spray foam expands into every crack, hole, or open space to completely fill an entire area. Certified technicians are trained to know exactly how much spray foam to allocate so that there are no open spaces.
Not all insulation prevents moisture and air from coming through the walls. Even traditional fiberglass insulation allows moisture and air to get through. Spray foam, however, is non-absorbent. It blocks air and water and keeps it from coming inside the home.
