Why choose spray-in-place polyurethane insulation?
Polyurethane is one of the most versatile polymers in use today. Its chemistry is based on the reaction of an isocyanate with a polyhydroxy compund (polyol). A polyurethane foam-in-place system is a combination of the two components that have been pre-formulated so they need only to be mixed and dispensed to make polyurethane foam.
This quick expanding liquid fills all gaps, voids, and conforms to any shape. The cured foam forms a solid, fully adhered, monolithic insulation envelope.
The resulting envelope offers a high R-value. What is an R-value? Its use is limited to situations where thermal insulation is achieved by retarding the flow of heat through the material itself rather than reflecting radiant heat away. The higher the R-value, the greater the insulation.
For new or rehabbed construction, this allows for reduced exterior wall depth, increasing interior space and reducing the wood required.
Spray foam insulation forms an air barrier that stops air flow into and out of your structure. It reduces noise, blocks dust, pollen and other airborne contaminants for improved indoor air quality.
Additionally, the residential insulation system is formulated to contain an anti-microbial to inhibit mold, mildew and bacterial growth.
Polyurethane insulation and its applications
Typical applications include:
- New construction walls, attics, basements
- Remodels or additions
- Basements, crawlspace
- Agricultural buildings
- Commercial buildings
More on R-Values
There are two kinds of R-Value: Rated and Actual, but the Rated value often doesn’t tell the whole story.
Insulation systems other than SPF, especially when not installed perfectly, are susceptible to uncontrolled air leakage, and air infiltration accounts for up to 40% of your energy loss, according to the U.S. Department of Energy (DoE). This means its Actual value can be a lot lower than its Rated value promises.
