AIRTIGHT Occupational Safety and Health Administration (OSHA) Permissible Exposure Limit (PEL). In addition to ensuring that the job site is adequateer range of climate conditions. Some manufacturers have reﬁ ned SPF so that it may be installed in cooler ambient temperatures, reducing the tors, as their radiant heat also may damage the SPF material before installation. When installing, the contractor should open the “B” drums slowly, and preferably, open them as early as possible on the day of installation. In summary, SPF insulation provides various beneﬁts to homeowners, such as significant energy savings, improved air quality, reduced risk of wood rot and mold growth, and reinforced structural integrity. The contractor, however, must be adequately trained and have the appropriate safety and installation equipment to deliver these beneﬁts. W&C Dave Distler is vice president and general manager for the Resin Technology Business Unit of Henry Company. The Resin Technology unit, based in Ontario, Calif., is the leading producer of roofing systems, a pioneer in polyurethane technolog y and the manufacturer of PERMAX Spray Polyurethane Closed-Cell Foam insulation. The airtight seal that SPF provides inhibits vapor and resists the permeation of moisture through walls and roofs. ly ventilated, contractors must use the proper respiratory protection. When selecting the appropriate respiratory protection, the contractor should consider the air concentration of various contaminants in the spray mix. Air monitoring is one example of assessing the concentration of contaminants, and uses a calibrated pump system. The contractor will know then what level of protection is required of the respiratory protection equipment. Advances in SPF have enabled contractors to install it under a widnumber of occasions when weather conditions will interfere with completing jobs. Warmer temperat u res require additional preparation of the work area and the SPF material to ensure the proper adherence and curing. Among these precautions is to avoid storing “B” drums in direct sunlight. Exposure to direct sunlight may increase the foam’s temperature by as much as 40 degrees Fahrenheit and cause boil-over. “B” drums also should be kept away from air compressors and genera- Walls Ceilings Drywall Stucco Lath Plaster If you’re in need of wall and ceiling resources tools, the AEC Store can help!
