during the last 30 years, the standard has changed!
Within the last ten years StoneMill has steadily increased our use of Spray Foam in Sheridan, WY and surrounding areas. We use Spray Foam in all of our new homes because it is an energy efficient, cost-saving solution, and offers a sizable return on your insulation investment compared to traditional fiberglass. With the money you will save in energy costs, spray foam insulation pays for itself within a few years.
In addition, spray foam insulation out-performs traditional fiberglass insulation in every way, and will remain intact and last for the life of the home or building. Spray foam will continue to efficiently insulate, whereas traditional fiberglass sags and settles over time, causing it to no longer perform at its original R-value.
StoneMill currently uses industry leading polyurethane spray foam products and follows the most current application techniques.
What's the difference ?
Closed-cell or "hard-foam" spray foam is much denser than open-cell foam. The cell structure is smaller and more compact, allowing it to provide a prominent air barrier as well as a good water vapor barrier. Increased rigidity between studs, rafters, and floor joists also contributes to a much stronger structure with decreased squeaking and shifting. This type of spray foam insulation is typically used for roofing projects, crawl spaces or outdoor applications for which open cell spray foam is not recommended. It can also be used anywhere inside the home.
We use this high-performing, versatile spray foam insulation for commercial and residential construction. The unique formula incorporates recycled plastic bottles and renewable oils to create a high-performing, closed-cell spray foam insulation. Our foam has a high R-value of 7.4 at 1 inch, and a density of two pounds and is developed with 14% recycled content.
Open-cell or "soft-foam" spray foam insulation is least expensive because its formula does not require a significant amount of chemicals. The open-cell makeup of this foam makes it a solid and efficient air barrier. Although it does not provide any type of water-vapor barrier, it does provide sound reduction. This is because it is able to decrease the movement of air and minimize vibration between the studs. Open-cell spray foam is sponge-like in appearance and offers minimal resistance to deformation. Given its inability to prevent water vapor, it is not recommended for outdoor applications.
Our soft-foam is a cutting-edge formula of open-cell spray foam insulation, which expands 120 times its liquid volume, insulates and seals all cracks, gaps, and joints with a single application. This translates to lower energy bills for you.
The soft-foam we use is a spray-applied adhesive, which once applied, expands in place using water-blown technology, without CFCs, HCFCs, or ozone-depleting chemicals. Unlike traditional fiberglass insulation, our spray foam will maintain its performance; time and temperature have no effect on the spray foam insulation's R-value of 3.5 at 1 inch. It will never deteriorate, decompose, compact or settle and it will retain its shape and half-pound density over time.
R-Value is a indicator of an insulation product’s ability to block heat energy transfer. The R-Value for open cell spray foam insulation is roughly equal to the R-Values for cellulose and fiberglass. The R-Value for closed cell spray foam insulation is significantly higher.
