Insulation Contractor is a versatile insulation material that can be used for a variety of applications. But jumping into the industry can be like learning an entirely new language with terms such as “open-cell,” “closed-cell,” and R-Value being thrown around frequently.
To understand how spray foam works, it helps to understand its internal structure. Both open and closed cell spray polyurethane foam (SPF) have top-notch insulating properties, but their differences stem from the cell structure and density of the product. Open-cell spray foam is a bit like a yellow sponge and has large pockets of air, whereas closed-cell is more denser and yields more finished product for its raw materials.
Spray Foam Insulation: Transforming Homes with Efficiency and Comfort
Both forms of spray foam start as liquids with fast-reacting ingredients such as isocyanate and polyol resin that expand to create the foam once mixed together. The “A” side of the product consists of a volatile organic compound such as methyl diphenyl diisocyanate or methylene diphenyl diisocyanate and the “B” side contains a blend of polyols, catalyst, blowing agent and flame retardant.
The reaction between the chemicals causes the foam to expand up to 30-60 times its liquid volume. This expansion makes it ideal for sealing gaps and voids as well as providing an air barrier in areas such as rim joists, crawl spaces and walls.
In addition to insulating, spray foam also provides a seal for ductwork and prevents water leaks as well as deterring pests such as termites. It can also be used as a sound barrier and for blocking vibrations from appliances such as washing machines.
