BASF spray polyurethane foam (SPF) delivers a unique combination of properties to a highly functional building envelope. The closed cell rigid formulation contributes to an effective air barrier as well as providing required thermal insulation.

SPF is being used increasingly in residential construction to create insulating air barrier systems that improve comfort, energy efficiency and structural life expectancy. Research shows that from 30 to 50 percent of building heat loss in both low- and high-rise residential buildings can be attributed to air leakage in and out of the structure.

Typical applications of SPF in low-rise and high-rise residential building envelope systems include.

• Wood framing
• Metal framing
• Foundations
• Slab on grade
• Crawl spaces
• Attics
• Garages
• Cathedral ceilings

• Superior insulation
• Virtually air impermeable
• Fully adhered
• Seamless, no holes or gaps
• Will not sag or settle
• Will not rot or deteriorate
• Resistant to HVAC pressurization
• Adds structural strength
• Reduces noise transfer
• Resists unwanted pests

• Improved occupant comfort from reduced heat loss/gain and reduced drafts.
• Lower energy costs from improved thermal efficiency.
