Injection Foam Insulation

Our Services >  Injection Foam Insulation

Seal Right professionally installs Tripolymer Injection Foam; a premier foam insulation material that is one of the safest, most long-lasting and eco-friendly wall insulation products available.
Tripolymer® foam insulation was developed by C.P. Chemical Company, Inc. in 1966 for use as a fire resistant thermal and acoustic insulation product to be utilized in commercial and residential structures.         


In 1975, Tripolymer® 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 Tripolymer® as one of three products from a total of 7,000 to assist in further development.

After three years of intense research and testing, Tripolymer® 105 greatly surpassed all of the D.O.E. and C.P. Chemical’s expectations, and was made available for commerce.

Foam insulation fills the stud cavity, the air gap between the brick/sheathing, or both

Unlike some building materials, which can be extremely flammable and emit large amounts of toxic gasses when burning, Tripolymer® 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.


Tripolymer® 105, being composed of modified phenolic based methylene bound copolymers, is an extremely stable product. Unlike urea formaldehyde foam products, which have a tendency to decompose over time, samples of Tripolymer® foam installed under cement slabs for over 25 years show virtually no signs of damage from water, bacterial action, or mechanical stresses.

Foam insulation is easily installed in garage and interior walls through the drywall.

Tripolymer® 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.

Tripolymer®, with its extreme fire resistance, has been used extensively in schools, hospitals, universities, airports, and residential housing as insulation and soundproofing. Also, Tripolymer® 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 Tripolymer® 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 Tripolymer®’s fire resistance qualities.


Being of unique and patented chemistry, Tripolymer® foam insulation differs greatly from cement and urea formaldehyde foams.Tripolymer® 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.Tripolymer® foam is right at home when used in interior and / or exterior wood stud or steel frame wall systems.
