    What Is Spray Foam?

    Spray foam is a commonly used term for various chemically engineered insulation products.  Some people are familiar with single cans of insulation products found in their local hardware store; this is called one-part spray foam, meaning it is a continuous mix that can be applied to specific, smaller areas of need. This form of BCX0 commercial or residential spray foam insulation is intended for “quick fix” use, not long-term or large-scale insulation requirements. 

    For larger commercial spray foam insulation jobs like covering an entire ceiling area, attic, crawl space, or wood-framed walls, professionals utilize a two-part foam that combines isocyanate catalysts with polyol resin at the application nozzle. When mixed during the spray process these two materials react to each other creating a specially engineered insulation product capable of expanding to 30-60 times that of its liquid state. Spray foam fills cracks and voids while adhering to irregular surfaces, making it especially effective in insulating homes.
