    "Spray polyurethane foam (SPF) is an exciting insulation product that is exploding in popularity for many reasons. Among its many outstanding attributes are several that could be understood by consumers to be “green” attributes - for example, some SPF is made in part with natural oils, giving the foam some renewable content. And because SPF is an outstanding insulator, it can contribute significantly to home and building energy efficiency and energy savings." Prepared by SPFA

    page_white_acrobat How "Green" Is SPF?
    "In the case of SPF, this applies foremost because of the increase in energy efficiency it provides. A product that reduces energy use and the pollution required to produce that energy is generally considered "green. One of the criteria used by the Partnership for Advancing Technology in Housing (PATH) in determining a "green" product is that it is "made from reused, recycled, rapidly renew- able, and preferably local materials. SPF meets this need as most products are based on some level of various renewable resource

  • Air Sealing Homes

    page_white_acrobat Air Sealing: Seal Air leaks and Save Energy!
    "The most common insulation, fiberglass, does not stop air leakage. In older homes, dirty fiberglass is a telltale sign of air movement (it simply collects dirt like a filter).

    "[Houses] feel more comfortable because the additional insulation keeps the interior wall at a more comfortable and stable temperature. The indoor humidity is also better controlled, and drafts are reduced. A tightly sealed air/vapor retarder reduces the likelihood of moisture and air seeping through the walls. They are also very quiet because the extra insulation and tight construction helps to keep exterior noise out better." Prepared by the National Renewable Energy Laboratory.

    page_white_acrobat Insulation a Slab with Spray Foam
    "Perhaps the greatest advantage SPF offers is that it provides a monolithic layer of insulation, with no seams or other imperfections in the thermal barrier. Because it bonds aggressively and completely to just about anything it contacts, the foam creates a superior vapor barrier around plumbing and other slab penetrations." Prepared by Mike Pindell

  • Vapor Barriers

    page_white_acrobat Why Flash and Batt Makes Sense
    "A minimum of 1 in. of closed-cell foam, the “flash” layer, is used to seal the framing cavity and raise the temperature of the condensing surface (the inner face of the nearly impermeable foam, in heating climates) to prevent moisture- laden indoor air from condensing on the exterior sheathing. Open-cell foam’s lower cost may be tempting, but its relatively low R-value, vapor permeance, and high expansion rate make it a poor choice for flash-and-batt applications." Prepared by Michael Maines

    page_white_acrobat Spray Polyurethane Foam: The need for Vapour Retarders in Above-Grade Residential Walls
    "Closed-cell (about 2 pounds per cubic foot density or more) spray foam applied in thicknesses of over 2” (50 mm) will control vapor diffusion to safe levels in all climates up to 10000 HDD and interior winter-time relative humidities of up to an over 50%RH. As thickness increases the level of diffusion control increases. The diffusion control is equivalent to walls with the traditional fiberglass batt and polyethylene." Prepared by John Straube
