Homesulate foam insulation was developed by a leading chemical company in 1966 for use as a fire resistant thermal and acoustical insulation product to be utilized in commercial and residential structures.

In 1975, Homesulate™ foam products and their characteristics were expanded and refined with the help of a grant, provided by the United States Department of Energy, under the Federal Non-Nuclear Energy Research and Development Act of 1974 (Public Law #93-577).

Recognizing the inherent shortcomings of polyurethane and urea formaldehyde foams, the D.O.E. chose Homesulate™ foam as one of three products from a total of 7,000 to assist in further development. After three years of intense research and testing, Homesulate™ wall foam greatly surpassed all of the D.O.E. expectations, and was made available for commerce.

Unlike Polyurethane, which can be extremely flammable and emit large amounts of toxic gasses when burning, Homesulate™ will not drip or support combustion when subjected to fire, and the by-products of combustion are less toxic than those released from the burning of white pine, which is commonly used in residential home construction.

Homesulate™, being composed of modified non urea-formaldehyde copolymers, is an extremely stable product. Unlike urea formaldehyde foam products, which have a tendency to decompose over time, samples of Homesulate™ foam installed under cement slabs for over 25 years show virtually no signs of damage from water, bacterial action, or mechanical stresses.

Homesulate™ foam Insulation was specifically designed and formulated as a highly efficient thermal and acoustical cavity fill insulation. For 36 years, it has been specified and installed in more than 390 million square feet of new and existing commercial and residential construction.

Homesulate™, with its extreme fire resistance, has been used extensively in schools, hospitals, universities, and residential housing as insulation and soundproofing. Also,Homesulate™ has been used to increase the fire ratings of interior and separation walls where deficiencies exist.

When tested by independent laboratories (using the A.S.T.M. E-119 test criteria) with Homesulate™ wall foam installed in test walls, fire ratings were more than doubled in those wall systems. There is no other ‘foam in place’ insulation available that comes close to Homesulate™’s fire resistance qualities.

Being of unique and proprietary chemistry, Homesulate™ foam insulation differs greatly from cement and urea formaldehyde foams. Homesulate™ has a significantly higher activity index (solid content) than urea formaldehyde products, and does not wet or distort drywall systems as UF foams can during installation and drying. Homesulate™ foam is right at home when used in interior and / or exterior wood stud or steel frame wall systems.
