- What is spray foam made of?
Spray foam is made of polyurethane and are polymers. Companies such as Dow Chemical and DuPont are major suppliers of the polymers that are used in spray foam insulation.
- How is it applied?
Technicians use a spray gun to apply the expanding foam material to crevices, wall cavities, attic spaces and between joists.
- How will spray foam help lower my energy costs?
Spray foam creates an effective air barrier as well as a thermal envelope. This keeps heated air and cooled air from escaping and prevents cold air or hot air from entering your space. Your furnace or air conditioner don’t have to work so hard to keep a constant temperature and thus uses less fuel.
- What are the differences between open and closed cell foam insulation?
Open cell foam insulation has cells which have breaks in the tiny foam bubbles that make up the material Closed cell foam bubbles are in tact. Closed cell has a higher R-value per inch of thickness and is denser, providing a moisture barrier as well.
- Can spray foam insulation be used in existing homes as well as new homes?
Spray foam can be used in new construction and can be retrofitted into existing homes.
- Will spray foam interfere with electrical or other work in my attic?
Spray foam does not interfere with any work that will need to be done in your attic either now or in the future.
- How can I expect when the technician arrives to give me an estimate?

He or she will recommend the type of foam insulation best suited to the area and your goals for a more comfortable living space. Based on the measurements and thickness of the foam to be installed, the technician can give you an estimate right on the spot.
