Spray Foam FAQ

Spray Foam FAQ

Fiberglass batts are what have been the standard in home insulation for decades, however; spray foam insulation provides a higher R-value (resistance to heat flow) with superior coverage against air leakage. Spray foam comes in two different types; open cell and closed cell.

Closed cell has smaller pores and provides protection against air leakage and water vapor. This is a durable insulation that lasts the life of the home.

Open cell is sponge like and is best in walls as a sound barrier but it won’t protect against moisture.

What are the main benefits of closed-cell spray foam?

  • Drafts are virtually eliminated so a more indoor temperature is maintained
  • Minimizes noise
  • Eliminates the dangers of mold spores and growth
  • Adds structural strength
  • Never shrinks or settles

Will I void the warranty on my roof?

Every roofing manufacturer is a little different when it comes to warranties. Some warranties are prorated while others aren’t. Some cover labor and materials while others only cover materials. Certain warranties are transferable while others only cover the current homeowner and of course, the length of the warranty varies. Just like the terms mentioned above, each manufacturer has different criteria when it comes to what voids a warranty and what doesn’t so it’s important to understand what’s covered in your roof’s warranty and what actions you can take to not void that warranty.

What’s the difference between fiberglass batts and spray foam insulation?

Fiberglass acts like an air filter, attracts critters and does not prevent moisture build up.

Spray foam’s durable substance acts as water and animal barrier.

How does Spray Foam Insulation improve indoor air quality and comfort?

Spray foam insulation provides a sealed thermal envelope. When applied, the insulation conforms and fills each cavity, crack and void. By filling these voids the house is sealed against: wind, dust, moisture, pollen, spores, insects, mold and allergens. Spray foam insulation provides a healthier, quieter, draft-free, indoor environment with no harmful emissions that can cause allergic reactions.
