Spray Foam Insulation Options
Of all the many types of home insulation, spray foam has the competition beat in terms of R-value, resistance to mold and moisture damage, durability, air sealing, and versatility.
How Spray Foam Insulation Works
Pressurized cans of “one-part” spray foam are used primarily for sealing gaps and cracks. You may have seen these at your local hardware store and may have even used them in the past. Our system uses a similar product, but in a much larger application. With 2-part spray form, we mix resin and catalyst compounds at the application nozzle. Combining these ingredients starts a chemical reaction that creates expanding foam. For large area’s, such as attics, our specialized trucks and equipment pump the ingredients up to the application nozzle where the resin and catalyst compounds mix to create foam.

Closed-cell spray foam insulation
The large-scale insulation jobs performed by these contractors require special equipment as well as safety gear during installation. When the foam cures and hardens just several minutes after application, it’s completely safe for as long as it stays in place.
When properly installed, SPF (Spray Polyurethane Foam) creates a highly insulated building assembly that’s also free of energy-wasting air leaks. To see if spray foam is a wise option for improving your home’s comfort and efficiency, contact us today for a free quote.
Open-cell spray foam insulation
Open-cell spray foam insulation is light and sponge-like. The cells from which it is made break or pop as the foam expands and before it sets. Consequently, most cells are “broken” or open. (Think “kitchen sponge” but much smaller.) Like closed-cell insulation, it serves as an air barrier but unlike closed-cell foams, it allows water vapor to enter and pass through it.
Open-cell spray foam is light, typically only 0.4 to 0.5 lb. per cubic foot, and therefore does not substantially affect structural loads. It is generally considered more environmentally friendly than other foams because water is used as the blowing agent. In addition, open-cell foam provides excellent sound control.
