Oak Ridge Foam & Coating Systems, Inc. manufactures a wide variety of expandable polyurethane spray foam insulation products for many uses. Foams can be broken down in two ways. The first is related to how the foam expands. We provide both water blown and gas blown foam, which relates to what chemical is used to make the foam expand. Water blown foam obviously uses water vapor to provide the expanding function while gas blown foam uses a gas made in the chemical reaction between the A & B components to provide the lift.
Foam can also be broken down between open cell and closed cell foam. Open cell foam has open gas cells and is usually a very light foam with a large amount of expansion. It is very useful for sound deadening and insulation in interior walls. It does not provide a vapor barrier and is not recommended where moisture is an issue. Our .5-pound foam is an open cell product. The .5-pound rating relates to the density of the foam in pounds/cubic feet.
Closed cell foam has sealed cells that provide a vapor barrier and will absorb very little water. These foams are more rigid and provide a higher “R” value per inch of thickness. The most common spray foam insulation we make in this category is our 2-pound product. It produces an “R” value of 7 per inch of thickness. It is an excellent foam for residential and industrial insulation.
We also produce a 3-pound foam used for roofing in conjunction with a polyurea cover coat. This produces a very durable, long lasting roof that can be applied over many different substrates.
A rapidly growing segment of our business is concrete jacking foam. This 2.5-pound product provides precise, controllable lifting and leveling of concrete in residential, municipal and industrial applications.
Other foams can be developed for your specific needs.
