Spray foam insulation is a material applied as a liquid that expands into a foam, creating an air-tight seal in walls, attics, basements, and crawl spaces. It helps reduce air leakage and improves energy efficiency in homes.
There are two main types: open-cell and closed-cell. Open-cell foam is softer and provides sound dampening, while closed-cell foam is denser and offers a higher R-value and moisture barrier.
Spray foam insulation can last over 20 years without degrading if properly installed. It doesn't sag or settle over time like traditional insulation materials.
Yes, once cured, spray foam insulation is inert and safe. Proper installation includes allowing time for off-gassing and ensuring the area is ventilated during application.
Technicians apply it using specialized equipment that sprays the liquid mixture onto surfaces. It expands rapidly to fill gaps and cracks, then hardens into solid insulation.
Most residential projects take one to two days, depending on the size of the area being insulated and site preparation needs.
Common areas include attics, walls, basements, rim joists, crawl spaces, and around ductwork. It can also be used in new builds and retrofits.
Spray foam offers higher R-values per inch, air sealing properties, and moisture resistance, whereas fiberglass and cellulose are less effective at sealing air gaps and can retain moisture.
Yes. Because of its air-sealing qualities and high R-value, it can significantly reduce heating and cooling costs by improving overall energy efficiency.
Open-cell spray foam offers sound dampening benefits. It absorbs sound vibrations better than closed-cell foam and traditional insulation types.
In many cases, yes. Improved energy efficiency and modern insulation can be attractive to buyers looking for long-term savings.
Closed-cell spray foam acts as a moisture barrier, helping prevent condensation and mold growth in walls, basements, and crawl spaces.
Yes. Spray foam can be applied in retrofit projects by accessing wall cavities, attics, and crawl spaces. Some preparation and access modifications may be needed.
Closed-cell spray foam has an R-value of approximately 6 to 7 per inch, while open-cell has an R-value around 3.5 to 4 per inch.
Yes. Depending on the location and application, vapor barriers or ignition barriers may be required to comply with building codes. A professional installer will ensure compliance.
Cost depends on the size of the area, type of foam used, and site conditions. Generally, it's more expensive upfront than fiberglass but offers long-term energy savings.
Spray foam typically requires no ongoing maintenance once installed. It's durable and doesn't settle or degrade over time under normal conditions.
