Application of Spray Foam Insulation

Spray Foam Insulation for the Dallas & Fort Worth Metro Areas

What is spray foam?

Spray polyurethane foam, known as SPF, is the most efficient insulation method for both residential and commercial buildings. This type of insulation provides a continuous, uninterrupted air barrier that dramatically reduces and eliminates air leakage.  Reducing air leakage and heat loss / gain is the best way to reduce your energy bills.

  • Higher insulation R-value
  • Provides a seamless air barrier
  • Restricts moisture transmission
  • Adds structural Strength
  • Minimizes sound transmission
  • Does not shrink or settle

We install both SPF wall insulation and roofing insulation products to provide you with a healthier, warmer home or business throughout the year. We also install a range of specialized coatings for use in moisture and thermal protection, abrasion resistance and waterproofing. These work together to enhance your building’s envelope, providing you with energy efficiency, sustainability and increased comfort all year round.

Open Cell & Closed Cell Foam

Open cell foam (also known as semi-rigid foam or 0.5lb foam) has a much softer feel than closed cell foam, much like a pillow or cushion because the cells, or bubbles, are not completely sealed, allowing air from outside to fill the gaps in the foam.

Closed cell foam (also known as rigid foam or 2lb foam) feels much harder, though this hardness varies depending on the density of foam used. The cells in closed cell foam are completely sealed, resembling inflated balloons compacted and piled on top of each other. This configuration makes for a much stronger and more rigid material because the sealed cells can withstand much more pressure than open cells, much like how a car tire works. Special gas is used to fill the cells in closed cell foam in order to provide the highest possible insulation value. The insulation value of open cell foam, while still good for most purposes, is less than that of closed cell foam because the material is less dense.

Both types of products have advantages. Closed cell foam is much stronger, providing greater structural strength, while it also provides more resistance to air and water vapor. However, the increased density of the material makes it much more expensive. The choice of which foam to use will depend on circumstances such as the insulating characteristics required for each building.

Injection Foam

Injection foam or wall foam has a range of applications and provides superior insulating qualities due to its excellent acoustical and thermal properties. One of the major uses of this type of product is to insulate existing homes and buildings with minimal work. It can be injected under pressure into concrete blocks and cavity spaces, completely filling up the voids and sealing them, becoming “cured” or set in about 60 seconds. It is also used on new construction projects, as it has the advantage that it is installed after construction has been completed, allowing the contractors to work uninterrupted which leads to faster project completion and less costs.
