The use of spray polyurethane foam continues to grow among builders, contractors and architects who understand its superb ability to seal the building envelope. Acting as a single-source solution, SPF accomplishes what would normally require multiple products. However, like most organic materials, SPF is combustible and, when unprotected, may ignite and cause flash fire. Thus it is necessary to also utilize thermal and/or ignition barriers to ensure safety in the use of SPF.
Unlike other insulation solutions, SPF possesses the unique ability to insulate, seal against air and water and air leakage, as well as control moisture throughout the structure. Considered a “single-source solution,” SPF reduces the need for the use of multiple products. This sealing capability of SPF in the building envelope also directly enables the material’s superb energy efficiency in the structure.
