General Spray Foam Questions
What is spray foam insulation?
Spray foam insulation is applied as a liquid and expands to fill gaps, cracks and irregular spaces. Once cured, it creates a continuous insulation layer that can also reduce air leakage through the building envelope.
Where can spray foam insulation be installed?
Depending on the product and building design, spray foam may be installed in walls, rooflines, attics, crawl spaces, floors, ceilings, rim joists, metal buildings and other areas.
What is the difference between open-cell and closed-cell spray foam?
Open-cell spray foam is softer, lighter and more flexible. Closed-cell spray foam is denser, more rigid and generally provides a higher R-value per inch. Closed-cell foam also has greater resistance to water vapor. The correct product depends on the application.
Is spray foam insulation an air barrier?
Spray foam can qualify as an air-barrier material when the selected product is installed at the manufacturer-required thickness. Its ability to expand into gaps makes it useful for reducing uncontrolled air movement.
Does spray foam help control indoor temperatures?
Yes. By limiting heat transfer and reducing air leakage, properly installed spray foam can make indoor temperatures more consistent and reduce the workload placed on heating and cooling equipment.
Can spray foam help reduce outside noise?
Spray foam may reduce some sound transmission by filling cavities and limiting air pathways. However, a dedicated sound-attenuation system may be more appropriate when noise control is the main objective.
Can spray foam help deter pests?
Spray foam can close some of the cracks and gaps pests use to enter a building. It is not a pest-control product and should not replace professional treatment or structural repairs.
Is spray foam safe after installation?
Spray foam should be installed by trained professionals following product instructions and job-site safety requirements. Occupants and unprotected workers may need to remain outside the work area during application and for the manufacturer-specified re-entry period.
