Spray Polyurethane Foam (SPF) insulation keeps buildings cool in the summer and warm in the winter. Because it is applied directly to gaps, cracks, and other surfaces that contribute to heat loss, it both air seals and insulates. As a result of this “magic,” SPF insulation offers one of the most effective ways of weatherizing existing buildings and new construction.
When used following proper safety guidelines, SPF and polyurethane foam machines can help with many of the following:
Save On Energy Bills
According to the U.S. Environmental Protection Agency (EPA), homeowners that both air seal and insulate their houses can save nearly 20 percent of their cooling and heating costs, or approximately 10 percent total energy costs.
Why? SPF insulation resists heat transfer better than many other insulation materials, with R-values commonly in the range of 3.5 – 6.5 per one inch of thickness. R-value is the rating contractors use to gauge an insulation’s ability to resist conductive heat transfer. Higher R-values indicate greater insulating power.
Since SPF insulation helps reduce air penetration, it also helps stops moisture vapor from coming in and escaping a building, which helps minimize the load on cooling and heating systems.
SPF insulation also helps:
Reduce Air Conditioning and Heating Size
HVAC sizing is reduced nearly 35 percent without the loss of comfort or efficiency with SPF insulation, according to the Canadian Urethane Foam Contractors Association.
Minimize Noise and Drafts
- SPF helps reduce airborne sound transmission
- Polyurethane foam machines help create a more efficient air barrier.
- SPF is often used to reduce drafts from windows, doors, attics and floors, contributing to a more comfortable interior.
Block the Entry of Insects
Closing up gaps using a polyurethane foam machine from the exterior of a building provides a barrier against insects.
Seal Small Cracks to Insulate Walls and Roofs
Because contractors use polyurethane foam machines to apply SPF insulation on site, it makes it easier to seal and insulate small cracks commonly found in buildings and homes.
Qualify for Tax Credits and Utility Rebates
Thanks to the American Recovery and Reinvestment Act of 2009, the energy savings obtained by air sealing homes is considerable enough that the purchase and use of SPF products may qualify for tax credits.
The Act allows for a tax credit of 30 percent for the purchase of energy efficient products. Always check with the manufacturer for confirmation that the particular SPF product qualifies for the tax credit and further information.
Additionally, numerous local utility companies in the U.S. offer rebates for energy efficiency upgrades. Check with your utility provider for eligibility.
