Energy Efficiency

Up to 40 percent* of the energy used to heat or cool a structure is caused by air leakage. Inefficiencies may be even greater in older non-insulated structures. The upfront cost of Sprayed Polyurethane Foam (SPF) is easily made up for by its cost saving benefits.

Conventional batten insulation in conjunction with home wraps such as Tyvek is often used in an attempt to seal in air and reduce air infiltration. SPF forms an air and moisture barrier, thereby eliminating both air escape and intrusion.

Moisture build-up in traditional insulation materials reduce that insulation’s R-value, contributing to heat loss. Historically, roofs were vented to prevent moisture buildup. As heat rises within a structure, it then escapes through these vents. Research shows that moisture under roof areas originates from damp basements and crawl spaces - as well as living spaces. By insulating with SPF in these areas surface temperatures and resulting moisture from condensation are virtually eliminated along with the need for roof venting.
