What is spray foam insulation?
Spray foam insulation is a polyurethane foam material that is applied as a liquid and expands after application. It helps fill gaps, cracks, and cavities to create insulation and air sealing in one system.
Spray foam can be used in many areas of a building, including attics, walls, basements, crawl spaces, garages, additions, commercial spaces, and renovation projects.
Main benefits of spray foam insulation
- Air sealing
Spray foam helps reduce air leaks by sealing cracks, gaps, and hard-to-reach spaces. - Thermal insulation
It helps improve energy efficiency by reducing heat loss in winter and heat gain in summer. - Moisture control
Closed-cell spray foam can help reduce moisture movement when installed correctly in suitable areas. - Comfort improvement
A better-insulated and air-sealed space can feel more comfortable and consistent. - Useful for renovations
Spray foam is often used in renovation projects where existing spaces need better insulation or air sealing.
Spray Foam GL works with different spray foam types depending on the project's needs.
Open-cell spray foam is lighter and commonly used for interior applications where sound reduction and air sealing are important.
Closed-cell spray foam is denser and stronger. It provides a higher insulation value per inch and is often used where moisture resistance, strength, or limited space are important.
Where spray foam may be used
Spray foam may be used for:
- Attic insulation
- Basement insulation
- Garage insulation
- Wall cavities
- Crawl spaces
- Renovation projects
- Commercial insulation
- Building envelope upgrades
The best type of spray foam depends on the building area, moisture conditions, required insulation value, access, and project goals.
