Frequently Asked Questions
After a 24 hour cure period spray foam insulation is non-toxic and completely safe.
If we spray the roof deck we have to heat and cool the attic. How does this save us money on utilities?
Spray foam insulation is either open-cell or closed-cell. While both are exceptional, they have different costs, applications, and capabilities.
All spray foam insulation is made up of many tiny cells or bubbles. With open-cell foam the cells are open, which gives it a soft feel and a lower density. Open-cell spray foam has a lower insulating value than closed-cell (about R-3.5 per inch). Open-cell foam is ideal for most residential applications in walls, floorspace, and attics. It has exceptional noise reduction and is less expensive than closed-cell.
Closed-cell spray foam has closed cells or bubbles that are more tightly packed together and the cells are filled with a gas instead of air as with open-cell foam. Closed-cell foam is stronger (rigid), resists air and water penetration, and is the superior insulator (R-7). Closed cell foam strengthens a structure due to its rigidity.
