Types of Spray Foam & Why Spray in Foam is Better
Building a new energy-efficient home that is also affordable can require a great deal of thought and planning, but smart homeowners, architects, and builders know the best choice for insulating new homes is WITHOUT A DOUBT — spray foam insulation — there’s no better choice for efficient & comfort!
How is Spray Foam Insulation Different?
Spray foam is a cost-effective and environmentally-friendly alternative to fiber insulation, such as fiberglass or cellulose. While other insulation systems may seem cheaper, they don’t measure up to spray foam insulation when it comes to your monthly home energy savings. How much will you save? Our experience shows that spray foam insulation can help homeowners save as much as 40% to 50% on monthly energy bills.
Savings aren’t everything though. Spray Foam Insulation creates an impervious barrier that blocks out pollen, pollutants, irritable dust—and reduces noise penetration up to 80% making your home healthier, quieter, and ultimately more comfortable for you and your guests.
Seal It Sprays Two Different Types of Foam
Open Cell Foam: Open cell foam is impeccably light and soft, with an R-value of R4 per inch of thickness that expands to 100 times its volume during installation. The rapid expansion of the open cell foam ensures that the foam will reach deep into all of the cracks, crevices and voids in your walls, behind your electrical boxes, and within your roofing system. Standard thicknesses are a nominal 5 inches sprayed into 2 inch by 6 inch wall cavities, resulting in an R20, and a nominal 7 inches sprayed into a typical roof system for an R32. Open cell foam provides a 99% air barrier, and therefore stops 99% of air borne water (i.e., water vapor), and is especially well suited for new construction. Because of its soft pliability, open cell foam can twist and deform with structural components as they dry out over time, hence not sacrificing any of its insulating ability. Want to know more?

Closed Cell Foam: Closed cell foam is a dense foam that cures to a very hard surface, and has an R-value of R6.5 per inch of thickness. Because of its denseness, closed cell foam provides a moisture barrier as well as an air barrier, and is thus very suitable for building renovations where there may be shallow stud and/or rafter depths, and is also very suitable for basements and crawlspaces where the potential for dampness and moisture may be present. Standard thicknesses are a nominal 3 inches in wall systems for an R21, and a nominal 5 inches in roof or ceilings for an R35. Check out our full production specifications.
