Tripolymer Injectable Foam

One of the drawbacks to spray foam insulation is that it can't be installed in a cavity that is closed on both side, such as the walls of an existing home. In 2009, Energsmart added Tripolymer® Injection Foam to our product line. Like spray foam, Tripolymer® has a proven track record of several decades. Read our paper on Flash and Batt Systems for a better understanding.

History

Tripolymer® is manufactured for Energsmart by the C.P. Chemical Company in White Plains, NY. Established in 1966, C.P. Chemical Company's principal activity has been the production, distribution, and marketing of Phenolic based resins, catalytic surfactants, and related foam generating equipment for servicing the construction industry.

For over 40 years, Tripolymer® has been using its exclusive line of foam products, and has grown from humble beginnings to a national company with dealers all over the United States.

In 1975, big changes took place. Tripolymer® foam products were expanded and refined with assistance from the US Department of Energy under the Federal Non-Nuclear Energy Research and Development Act of 1974. Recognizing the inherent shortcomings of existing foam insulation products (urea formaldehyde foam), the D.O.E. concluded that Tripolymer® foam and its related products were in the "national interest". Tripolymer® was chosen as one of three products from a total of 7,000 to be assisted in further development. After three years of intensive research and testing, the new Tripolymer® insulation was made available for commerce.

Installation

As discussed above, the beauty of injection foam is that it can be used in existing home walls even if the wall already has older insulation in it. Energsmart's technicians typically install injection foam by opening up the outside of the home by removing siding and drilling a 3" hole in the underlying sheathing. That hole creates access for us to insert a tube into the cavity to inject it with foam. The foam used is a slow curing cellular plastic that has the consistency of shaving cream when installed. Injection foam has fluid-like properties and is put in under pressure, both of which allow it to penetrate the smallest cracks and hard to reach areas. Over a period of two to three days the product hardens leaving a stable high R-value cavity insulation. We can reach R-18 in a 2x4 wall cavity!

When the install is complete Energsmart will plug the holes used to access the cavities and return the siding to the home. All overfilled product is simply sprayed off with a garden hose and will not harm your landscaping.

Energsmart can install this product with confidence in buildings with pretty much any type of exterior, including brick, block, and stone. In these cases we drill a 5/8" hole at the mortar joints, completely fill the cavity, and then patch the mortar to finish the process. Many competitors of ours will attempt to fill these types of exteriors with blown cellulose or fiberglass, but this is nearly impossible to do without the product settling. Injection foam is a tremendous product that creates an air barrier just like our spray foam products.
