How Spray Foam Insulation Works

attic insulation is an eco-friendly, highly energy efficient product that provides the best value for your money of any home improvement project. It seals and insulates more efficiently than fiberglass or cellulose and can help lower heating and cooling costs significantly.

Debunking Common Myths About Spray Foam Insulation

The foam is made from 2 liquid chemicals, polyurethane and isocyanate which are sprayed together through a special application gun and chemically react to expand. The resulting material fills in cracks and crevices and creates an air-tight, durable insulation barrier that is resistant to water, mold and fungus.

Before installation, the crew will clean and prep the area to be sprayed – typically the attic, crawl space or rim joist in an existing home or new construction, pole barn or commercial structure. Then the crew will run a hose to the insulated area and spray the foam into place, covering all surfaces to be sprayed. The hose is attached to a large, high-end rig that ensures the proper mix and consistent expansion of the foam.

The rig will also monitor the temperature of the foam to ensure it is always at the correct density and consistency. It’s like making homemade whipped cream, only with far more precision. The foam is sprayed and bonded to the surface, expanding several times its original size, filling all the small nooks and crannies for an airtight, thermally efficient, sound-proof barrier. The foam will then harden and cure. Open and closed cell foam are available, with the main difference being in the way the small cells are encapsulated.
