spray polyurethane foam, health and safety

Why Select Insulating Foam Sealant?

Insulating foam sealant can be used to help air seal your home, contributing to improved comfort and energy efficiency. Because it is sprayed directly into the gaps, cracks and other surfaces that contribute to heat loss, it both insulates and air seals, offering one of the easiest and most effective ways of weatherizing existing homes and new construction.  When installed following proper safety and handling guidelines, insulating foam sealant can…

Help save on energy bills*

  • The U.S. Environmental Protection Agency estimates (for all insulation) that homeowners who air seal and insulate their homes can save up to 20% of heating and cooling costs (or up to 10% total energy costs).

*Savings vary. Find out why in the seller's fact sheet on R-values. Higher R-values mean greater insulating power.

Reduce drafts, noise and increase comfort

  • Insulating foam sealant is an effective air barrier.
  • It is commonly used to prevent drafts from windows, doors, attics and floor boards creating a more comfortable indoor environment.
  • It can help minimize air-borne sound transmission.

Impede entry of insects and pests

  • Sealing gaps with insulating foam sealant from the outside provides a barrier against insects and other pests.

Minimize air infiltration that can generate condensation and result in mold growth

  • Gaps and cracks in the building envelope can allow uncontrolled movement of moisture-laden air in and out of the building.  Loss of interior moisture control can make the interior air excessively dry or moist, which can cause occupant discomfort, poor indoor air quality, higher heating and cooling costs to control moisture, and in some cases, hidden deterioration of the building and possibly mold and mildew growth.  Air sealing these gaps and cracks with insulating foam sealant can help control interior moisture levels.

Seal small cracks and gaps

  • Because insulating foam sealant is spray-applied on site, it can more easily insulate and seal the small cracks and gaps common in homes.  Depending on the type of application, there are also professional types of spray polyurethane foam intended for trained weatherization professionals or SPF contractors to use on larger insulation and air sealing projects. (See "Types of SPF insulation and how it's applied")

Qualify for utility rebates, tax credits and green certification

  • Depending on the scope of your weatherization project, the energy savings obtained by air sealing homes is significant enough that the purchase and use of some spray polyurethane foam (SPF) insulation products may qualify for tax credits under the new American Recovery and Reinvestment Act of 2009. The American Recovery and Reinvestment Act allows for a tax credit of 30% on the purchase of energy efficiency products, up to a maximum of $1500 per year in 2010. Check with the manufacturer for confirmation that the specific SPF product qualifies for the tax credit and for further information and instructions on filing for the credit.
  • Many local utility companies offer rebates for energy efficiency upgrades. Check with your utility provider for eligibility.
  • To learn more about federal tax credits for energy efficiency, you can visit the ENERGY STAR web site on Federal Tax Credits for Consumer Energy Efficiency.
  • For new construction or major remodel projects, the use of SPF may help earn energy-efficiency credits under residential green certification programs. A few sources you can visit include:
