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.
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.
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.
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.
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.
No, our spray foam is an inert substance. Therefore, it does not support bacteria, mold, or fungal growth.
No, our spray foam insulation has been thoroughly tested and is not a concern to electrical authorities, nor is it corrosive to metals.
