FAQ

1. What is spray foam insulation?

Spray foam insulation is a liquid-applied material that expands on contact to seal air leaks, insulate, and create a continuous thermal and moisture barrier.

2. What’s the difference between open-cell and closed-cell spray foam?

Open-cell foam is lighter and more flexible, while closed-cell foam is denser, provides a higher R-value per inch, and adds moisture resistance and structural strength.

3. Is spray foam insulation safe for my home?

Yes - when installed by a trained professional using approved materials and proper ventilation, spray foam insulation is safe and effective.

4. How long does spray foam insulation last?

Spray foam is designed to last the lifetime of the building and does not sag, settle, or degrade like traditional insulation.

5. Does spray foam insulation help lower energy bills?

Yes - by sealing air leaks and improving thermal performance, spray foam can significantly reduce heating and cooling costs year-round.

6. Can spray foam be installed in existing homes?

Yes - spray foam can be installed in existing homes during renovations, additions, or targeted upgrades such as basements, rim joists, and attic spaces.

7. Is spray foam insulation moisture and mold resistant?

Spray foam acts as a moisture barrier, helping reduce condensation and lowering the risk of mold growth.

8. Does spray foam insulation require ventilation?

Certain applications, such as sloped and flat ceilings, require ventilation per building code, which we install using approved ventilation flutes.

9. How much does spray foam insulation cost?

Costs vary based on area size, foam type, thickness, and preparation required, but spray foam offers strong long-term value through energy savings.
