  • What are the main benefits of insulating my home or business with spray polyurethane foam insulation?

    • Excellent insulation properties
    • Outperforms pink fiberglass
    • Reduces household energy use by up to 50%
    • Stops air leakage and infiltration, keeping cool air inside
    • Improved indoor air quality by significantly reducing the potential for mold, mildew, dust, allergens, and pollen to enter your home
    • Reduces outdoor noise, giving you a quieter home
    • Closed-cell spray foam makes walls stronger and more rigid
    • Insect and rodent infestation is reduced significantly since spray foam insulation is not a food or nesting source for them
    • Spray foam prevents moisture penetration, greatly reducing the potential for mold growth
    • Closed-cell spray foam eliminates the need for a vapor barrier
    • You can downsize your HVAC equipment by 30%
    • Reduced heating and cooling load on HVAC, meaning fewer repairs and breakdowns
    • The extra cost of spray foam is generally recouped within the first three years
    • Spray foam won't sag, shift, or degenerate, but it will perform throughout the life of your home
    • Homes insulated with spray foam have a higher resale value
    • Create a healthier, more comfortable living environment
    • Bio-based and non-toxic material
  • How does spray foam compare with fiberglass batts?

    • Fiberglass batts will not stop air leakage. Blown-in cellulose will slow down air leakage. However, spray foam will STOP air leakage. Spray foam is also mold and moisture resistant, unlike fiberglass and cellulose.
    • Fiberglass batts have an R-value of about 3.5 per inch. However, this is not a true R-value since there is no air seal. Blown-in cellulose has an R-value of about 3 to 4 per inch) but also no air seal. Our spray foam insulation has a true R-value of 3.8 - 6.8, depending on the density of the foam we use (1-inch thickness).
    • Fiberglass batts can sag over time and blown-in cellulose can settle over time, leaving sections of the stud cavity uninsulated. Spray foam insulation completely adheres to the wood studs and sheathing. This results in a permanently sealed barrier against air penetration and leakage.
    • Spray foam will add strength and rigidity to your house. FEMA now requires homes in hurricane-prone areas to be constructed with spray foam insulation to better withstand a storm's powerful winds.
  • What Is the R-value (insulation value) of SPF insulation?

    Ultimate Spray Foam offers a few different foam products of different densities. Our open-cell foam product has an R-value of 3.5 per inch. In most applications, a house constructed with 2x4 studs will have 3.5 inches of open-cell foam, resulting in a total R-value of 12. If the house is constructed with 2x6 studs, the R-value when insulating with open-cell foam can reach a maximum of R-20.


    Our primary closed-cell foam has an R-value of 7.0 per inch and is usually sprayed between 2 to 3 inches thick, resulting in an R-value between 14 and 21. Spray foam is the only insulation product that offers a true R-value because it is the only insulation that creates an actual air seal.

  • Which is better for my property: open-cell or closed-cell foam?

    While we spray both types of foam, the preferred choice has usually been closed-cell foam due to its higher R-value per inch, the strength it adds to the structure and its effectiveness as a barrier against moisture. While it is slightly more expensive, many owners and contractors prefer it due to these features. However, if your project has a limited budget, open-cell foam is a good choice.

  • How does spray foam insulation improve indoor air quality and comfort?

    Spray foam insulation creates a sealed thermal envelope. When applied, the insulation conforms and fills each cavity, crack, and void. By filling these voids, you seal the house against wind, dust, moisture, pollen, spores, insects, mold, and allergens. Insulating your home with spray foam gives you a healthier, quieter, draft-free, indoor environment with no harmful allergens that can affect your health.

  • How Is the Insulation Installed?

    Spray foam insulation is sprayed into the wall cavity in between its wooden studs with very specialized equipment. The foam is sprayed on as a liquid, and within 2 to 10 seconds, it will turn to foam and expand up to 100 times its original size. The foam fills every nook and cranny, sealing all gaps, and permanently adhering to the stud cavity.

  • How does spray foam insulation control moisture movement and condensation?

    Most moisture damage in a building occurs when warm, moist indoor air is exchanged with the cold, dry air within an insulation cavity. As the moisture in the air condenses, it forms dew within the insulation. Because foam insulation is an air seal, this will not occur.


    It is ideal for use in climates where buildings are both heated and air conditioned because the situation is reversed in the summer with moisture forming on the back of the interior vapor retarder.

  • Does spray foam insulation support bacteria, mold, or fungal growth?

    No, our spray foam is an inert substance. Therefore, it does not support bacteria, mold, or fungal growth.

  • Does foam insulation cause any electrical wiring to overheat or any problems to metal surfaces?

    No, our spray foam insulation has been thoroughly tested and is not a concern to electrical authorities, nor is it corrosive to metals.
