Spray polyurethane foam (SPF) is a versatile, expanding insulation and sealing material applied as a liquid that reacts and cures within seconds to minutes, forming a continuous, monolithic layer of rigid or semi-rigid foam. It is created on-site by precisely mixing and spraying two liquid components: an isocyanate (commonly referred to as the "A" side) and a polyol resin blend (the "B" side), which contains catalysts, blowing agents, and flame retardants. Upon mixing, a rapid chemical reaction occurs, generating heat and causing the mixture to expand 30 to 60 times its liquid volume as the blowing agent vaporizes. This expansion allows it to fill cavities, conform to irregular shapes, and adhere tenaciously to substrates, creating an exceptional air and moisture barrier. SPF is broadly categorized into open-cell (softer, vapor-permeable) and closed-cell (denser, structural, vapor-impermeable) foams, each suited for different performance requirements.

The primary application for SPF is in building and…
