Installation of STYROFOAM SPF Insulation
STYROFOAM™ Spray Polyurethane Foam (SPF) Insulation Product Information (124KB PDF)
Incorporating STYROFOAM™ SPF Insulation into your construction process is easy. The spray-applied liquid expands on contact and cures to a rigid foam, sealing and insulating all of the hard-to-reach places fiberglass cannot.
STYROFOAM SPF Insulation can be installed in new construction after the rough plumbing, electrical wiring, and heating and air conditioning ductwork are installed. In retrofit situations, the foam is sprayed between rafters and floor joists to increase airtightness in the attic and/or crawl space. When residing, a layer of STYROFOAM SPF can be sprayed in wall cavities and over wood studs before new sheathing and siding are installed, improving comfort and energy efficiency and adding to a home's resale value.†
Only personnel trained in spray polyurethane foam application should install STYROFOAM™ SPF Insulation.
STYROFOAM SPF Insulation contains isocyanate, hydrofluorocarbon blowing agent and polyol. Spray equipment must be capable of delivering the proper ratio (1:1 by volume) of polymeric isocyanate and polyol blend at adequate temperatures and spray pressures. Substrate must be at least 5 degrees above dew point, with best processing results when ambient temperature humidity is below 80 percent. Substrate must also be free of moisture (dew or frost), grease, oil, solvents and other materials that would adversely affect the adhesion of the polyurethane foam. Substrate temperatures should not exceed 120°F for STYROFOAM SPF 3049 (commonly referred to as "Summer" formula) and 100°F for STYROFOAM SPF 3062 (commonly referred to as "Fall/Spring" formula).
Due to the exothermic reaction of the isocyanate and polyol blend, mixed components should be applied in layers (maximum 2-1/2" thickness per layer). Allow foam to cool completely before applying successive layers.
Read the Material Safety Data Sheet carefully before use. Wear protective clothing, gloves, goggles and proper respiratory protection. Supplied air or an approved air-purifying respirator equipped with an organic vapor sorbent and a particle filter is required to maintain exposure levels below applicable ACGIH, OSHA or WEEL limits. Provide adequate ventilation.
