Frequently Asked Questions

Q: What is spray polyurethane foam insulation?

A: Spray polyurethane foam (or “SPF” or “spray foam”) is a rigid foam plastic that can be used for insulation in walls and attics, under roof decks, and on roofs and exterior walls. It air seals around walls, roofs, and corners as well as on contoured surfaces.

Q: How does spray foam insulation work?

A: Spray polyurethane foam (SPF) adheres to the wall, forming a continuous insulation and air barrier on the surfaces and cavities to which it is applied, even on contoured surfaces. SPF’s properties as an air barrier make it unique because a separate barrier does not have to be installed as an additional step in the retrofit or construction process.

Q: What are the benefits of using spray polyurethane foam insulation?

A: Spray polyurethane foam (SPF) insulates and acts as an air barrier, both of which are critical to making your home comfortable and reducing heating and cooling costs. There are no pieces to cut or seams to tape or caulk. In addition, SPF may reduce sounds transmitted through the air, add structural strength, and improve moisture control to help resist the formation of mold.

Q: How long will spray polyurethane foam last/be effective?

A: Spray polyurethane foam (SPF) resists settling, structural deterioration, and decomposition over time. In most wall and roof cavity applications, SPF should last the lifetime of the building. Ask your Miami Insulation Experts specialist for more information about the expected lifespan of the SPF being installed in your home.

Q: How long does installation take?

A: Installation time varies significantly depending on the size of the job and the ease of access to the site. A small amount of spray polyurethane foam (SPF) applied to a home’s interior can take as little as one to two hours to complete. Insulating an attic in most normal homes can be completed in less than a day. It is important to remember that while the foam can be installed fairly quickly, homeowners, children, and pets leave the home for the amount of time recommended.
