Types of Spray Foam
Spray Polyurethane Foam

Spray Polyurethane Foam

Spray Polyurethane Foam (SPF) insulates much better, pays back much faster in saved energy costs, adds structural strength, and (depending on the type of SPF used) achieves a high quality vapor-resistive barrier, sealing the cracks and gaps in your home against air and moisture leakage. With SPF, you save more on energy costs, reduce pollutants and allergens, and increase your protection against mold. An added benefit: it also protects your home from pests. Fiberglass and blown-in lose their insulating properties more quickly over time, while spray foam retains its effectiveness much longer.

2 lb. Closed Cell Foam Systems

Working off a gas molecule, the dense Closed Cell foam fills every void throughout its solid surface, allowing no air or moisture to pass through.

How it Works

Our Closed Cell Spray Foam is a two-component gas molecule blown spray foam. The two components, made up of polyol resin and isocyanate, are mixed to a 1:1 ratio and in an instant reaction, expand into a core density of 1.9-2.2 pounds per cubic foot. While Closed Cell Spray Foam provides superior thermal insulation for the interior of a building, it also stops all air infiltration when installed correctly.

Application

Upstate Spray Foam Insulation applies Closed Cell 2-lb. foam into open-wall cavities, crawl spaces, perimeter joists (any exposed rim or band joist), and cathedral/sloped ceilings at an industry leading heat resistance rating of R-7 per inch. While the product must be installed to local code, the amount of application varies. Our Closed Cell Foam, when applied correctly, creates its own vapor retarder (vapor barrier), and while it is being applied, fully cures to touch within 15 seconds.

Requirements

During application, all surfaces must be free of oil, grease, and debris. The surface must be dry as well. When applying Closed Cell Foam, the working area temperature must be a minimum of 40 degrees Fahrenheit. Unfortunately, Spray Foam systems cannot be installed into existing homes, unless the uninsulated surface is completely exposed.

Ending Result

Closed Cell Spray Foam is an excellent insulation choice, not only for its resistance to heat transfer, but for its water resistance and ability to air-seal your home or building. With these traits, the efficiency gained will contribute to significant energy savings throughout the life of a building, and will also benefit the owner by allowing the use of a smaller-capacity heating and/or cooling unit. The more efficient your home is, the less capacity you need! With the rising cost of heating, you are sure to see your return on investment in a short period of time using Closed Cell Spray Foam!

Just a Few Characteristics of Closed Cell 2-lb. Spray Foam

  • Heat resistance rating of R-7 per inch
  • Creates its own vapor barrier
  • Seals every nook and cranny when applied correctly, closing off possible air and moisture leaks or existing leakage areas
  • Seals around recessed lighting, electrical outlet boxes, wiring intrusions, and all bypasses
  • Adds 30% more structural strength to the applied surface

½-lb. Open Cell Foam Systems

 

How it Works

Our Open Cell Spray Foam is a two-component water blown spray foam. When its two components mix, they react instantly and expand into a low-density, open cell foam with an in-place core density of 0.45–0.55 pounds per cubic foot. Open Cell Foam provides thermal insulation for the interior of buildings. Open Cell systems only reduce air infiltration, where Closed Cell Foam systems stop it.

Application

Upstate Spray Foam Insulation applies Open Cell ½-lb. Foam systems into open-wall cavities, crawl spaces, perimeter joists (any exposed rim or band joist), and cathedral/sloped ceilings at a heat resistance rating of R-3.6 per inch. While the product must be installed to local code, the amount of application varies. All Open Cell Foam systems also require a vapor diffusion retarder (vapor barrier) after application. This system fully cures to touch within 15 seconds.

Requirements

During application, all surfaces must be free of oil, grease, and debris. The surface must be dry as well. When applying Open Cell Foam, the working area temperature must be a minimum of 40 degrees Fahrenheit. Unfortunately, Spray Foam systems cannot be installed into existing homes, unless the uninsulated surface is completely exposed.

End Result

In carrying half the R-value of Closed Cell Foam, Open Cell also lacks performance in condensation- or moisture-prone areas. Where Closed Cell Foam completely turns away and repels the moisture, Open Cell will absorb it into its sponge-like surface. Although Open Cell Foam must be applied in much greater thickness than Closed Cell Foam because of its low R-value rating, it is considered the next best insulation behind Closed Cell. Considered a semi-rigid foam, it adds minor structural strength to your home or building, while still filling every nook and cranny, sealing all voids from the outside elements.

Just a Few Characteristics of ½-lb. Open Cell Spray Foam

  • Heat resistance rating of R-3.6 per inch
  • Seals every nook and cranny when applied correctly, closing off possible air leaks or existing air leakage areas
  • Seals around recessed lighting, electrical outlet boxes, wiring intrusions, and all bypasses
