Since 1964, Acoustical Spray Insulators has done business as a commercial, industrial and institutional contractor specializing in the application of spray applied roofs and insulation for walls.  During our 30 plus years, ASI has installed a wide a spectrum of roofing systems ranging from single ply roofing, modified roofing and built-up roofing.  ASI has chosen to specialize in the installation of Sprayed-in-Place Polyurethane Foam Roofing Systems and Spray Applied Coating Systems.  Our specialized skills and talents enable ASI’s staff and personnel to fully utilize the versatility of sprayed polyurethane foam in all areas of construction. The major portion of our annual sales volume is the installation of sprayed polyurethane foam roofing on existing buildings. 

Sprayed polyurethane foam has been used in the construction industry for over 50 years and is recognized as the best insulator in the marketplace today. Polyurethane foam was invented during World War II and utilized in submarines and ships for flotation, thermal insulation and noise control. coating and overall energy. After the War, its primary use was in most all refrigerated trucks and trailers, which were insulated with urethane foam, as are most home refrigerators.  Because of the high insulating value in a compressed space.
 

ASI has been spraying polyurethane foam since approximately 1971 when we started off with small equipment doing freezers, coolers and pipelines, but in the mid 1970’s the energy crunch forced companies and institutions to think about putting insulation on their roofs since so many heating dollars were simply going up through the ROOF!  We demonstrated that the polyurethane foam roof systems is an economical way of adding insulation value to their roof and at the same time creating a leak-proof monolithic roofing system that is virtually impervious to water. 

A 1 1/2” application of polyurethane foam supplies an additional thermal value of R-10; this means to you that the roofing system can pay for itself by protecting the assets and capital equipment in the building and help to significantly reduce heating and cooling costs.

Polyurethane foam is compromised of a two part liquid raw product. A catalyst and resin are stored in our 24 ft. box trucks, which will come out to your facility for the roof system installation.  These two chemicals are pumped separately from drums into a Gusmer foam machine where both liquids are analyzed for weight and viscosity with an equal proportion of each liquid being sent through a series of pre-heaters and heaters.  Still as two liquids, the catalyst and resin are pumped through heated hoses to a foam spray gun; there the two liquids meet to form a heated chemical reaction, which is sprayed directly onto the roof.  As the chemicals meet and hit the surface it takes approximately 7 seconds for this chemical reaction to expand to forty times the original volume. The foam then cures and can be walked on in approximately 3 to 4 minutes without causing any damage. 

The fully adhered monolithic roofing system is impervious to water due to the 95% closed cell structure of the foam. The foam also achieves a 45 psi compressive strength and a 2.5 pound density.  The 95%  closed cell structure forms a 1 1/2” thick roofing membrane, which is impervious to water.

The Ultra Violet Rays of the sun are an enemy of any roof system. Polyurethane Foam Roofs are no exception. U.V. protection is provided on a Foam and Coating Roof by the installation of a sprayed elastomeric coating to all vertical surfaces, around the total roof perimeter, around all penetrations and over the main body of the roof. Either an Acrylic based or Silicone based coating would be used depending on the specific project constraints. The coating would be installed to a millage that would not require re-coating until approximately 12 to 15 years after the initial installation.

Stops leaks — Foam creates a water tight seal

Cost effective— Foam insulation layer provides superior insulation and energy savings

Improves roof drainage

The Application Process:

Step 1: Loose stone and dirt are removed from the existing roof.

Step 2: Self-Flashing Foam is
sprayed to all penetrations.

Step 3: The main roof area receives a seamless, 1 1/2 inch think coating of foam sprayed in place.

Step 4: Elastomeric Coating protects vertical surfaces, the perimeter, and around penetrations from U.V. degradation. A layer of gravel protects the main body of the roof from U.V. degradation.

Step 5: The finished roofing system is now easily maintained.
