Foam insulation is a two-part liquid that is sprayed in place by specially trained and experienced spray foam insulation contractors. The liquid mixture expands quickly foaming up to fill all gaps and voids in your home’s exterior walls, ceilings, roofs floors or crawl spaces. It cures to form a fully adhered, solid, monolithic micro-cellular insulation envelope.

We use NCFI polyurethane spray-on insulation it sets up as a rigid product. It is sprayed directly onto the back of the sheathing and sticks to it, swelling to 25 times its liquid volume. The foam itself is filled with microscopic bubbles. Since air molecules transport heat energy rapidly from the warm wall to the cold wall, the goal is to stop them or impede their movement with a web of cells inside the insulation. This insulation is also enhanced with Enovate, a Honeywell chemical that is added to the spray to create a new, slower, larger molecule that moves inefficiently to pick up and transfer heat. Heat transfer is therefore retarded in two ways, making for an extremely high insulation value. The foam comes as a two-part product, delivered as a liquid from two drums that mix the components through a sprayer. The liquid is sprayed at a very high pressure, about 2,000 pounds per square inch, to mix the chemical with the hardener and deliver it to the building cavity.
A two-part mixture is applied by trained professionals to the inside surface of exterior walls, to the underside of the roof, and beneath floors in basements and crawl spaces. The spray mixture expands rapidly to fill all cracks and voids, completely and permanently adhering to wood, masonry, metal studs and joists.
