Spray foam is a unique insulation and sealing product. The product is applied on site, so it conforms to the surface where it is applied. This application process creates a tight building envelope, which improves energy efficiency. Spray foam is versatile and can seal wall cavities, exterior walls, crawlspaces, attics, and small gaps and cracks throughout a house.  Spray foam products can limit air infiltration and air movement throughout the home, which helps reduce energy usage, limits intrusion of pollutants and allergens, and makes the home more comfortable.

 

    Spray foam insulation is a composite material formed when two chemicals (isocyanate and polyol resin, typically) meet. Kept in two separate hoppers or tanks and transported by gas pressure or a liquid, these chemicals meet at the tip of a spray gun. When they meet, they react to each other and create a foam solution. This foam then dries in place and creates an effective air and vapor barrier. Within this foam are little pockets known as “cells.” These cells create air gaps and barriers that make it difficult for heat energy and sound to pass through the foam. And, since the foam expands to the space in which it’s sprayed, these pockets will reach even the small nooks and crannies. These characteristics make spray foam a very effective insulator.

    How Does Spray Foam Insulation Work?

     Spray foam insulation entails the application of a liquid insulation material that expands and solidifies into a foam-like substance. It’s commonly used in both residential and commercial buildings to provide adequate insulation, improve energy efficiency and enhance comfort.

 SPRAY FOAM CAN:

  • Insulate and seal your home from air leaks. Insulating and air sealing your home will keep conditioned air from leaking to the outside, which can help lower your energy bills by 5% to 30% per year.
    • Open cell spray foam R-values start at: 3.5 per inch*
    • Closed cell spray foam R-values start at: 7 per inch*
    • Spray foam expands as it is applied to seal common gaps and cracks in a home.
    • Open cell and closed cell spray foam and spray foam sealants function as air barriers
  • Increase the structural integrity of your home. Spray foam can provide additional building strength and lower maintenance costs which lead to reduced repairs for roofing systems.
  • Make your home more comfortable. Spray foam decreases drafts and keeps all the rooms in your home the same temperature.
  • Improves Indoor Air Quality. Spray foam can seal your home to prevent allergens and moisture from entering the building’s interior where it is applied.
