Spray Foam Insulation (SPF) is a comprehensive insulation and air barrier system that seals walls, floors, and ceilings against air movement. It fills gaps around electrical outlets, baseboards, and where walls meet windows and doors, preventing outside air from causing drafts or cold spots. It also stops hot, humid air from entering and condensing inside walls, which can lead to mold, mildew, and premature decay.

Applied by certified installers, SPF is a semi-rigid, thermo-set polyurethane foam made of millions of microscopic cells. Its custom installation at the job site ensures a perfect fit for all cavity sizes and shapes. The low permeability to air, strong adhesion to other building materials, and flexibility make SPF more than just an insulator—it also provides excellent air leakage and sound control for residential construction.

Unlike loose-fill insulation, which fails to air-seal cavities and loses its R-value due to air infiltration, SPF maintains its R-value both in the field and in the lab. It effectively blocks cold air in winter and hot, humid air in summer, outperforming other insulation materials.

In addition to simplifying the construction process, SPF Insulation addresses major building envelope issues such as air-borne moisture movement and entrapment. Blower door tests on steel-framed homes with SPF Insulation—without a polyethylene vapor barrier—consistently achieve under the 1.5 ACH50 rating, indicating high energy efficiency. Heating and cooling costs are typically reduced by 30 to 50%, allowing for the use of smaller, more affordable equipment.

SPF Insulation is inert and stable long-term, maintaining its R-value without settling or compacting over time. It remains chemically and physically stable under normal conditions, with a temperature range of -60°F to 180°F.

SPF Insulation adheres effectively to steel studs and various natural materials such as cement board and wood, commonly used in residential and light commercial construction. Since SPF Insulation bonds to almost all surfaces, areas that should remain uninsulated—such as windows and doors—must be protected from over-spray.
