How long has this type of insulation been around?
Although spray foam has been around for more than 30 years, it has been perfected in the past 10 years and has now been made available in most major cities at very affordable prices.

At what stage is the insulation installed?
For new construction or renovations, the insulation is installed after the windows, doors and roof systems are in, the electrical, framing and plumbing inspections are complete, and after any other electrical or mechanical system located behind the drywall is installed. It is the last installation to take place before drywall installation. On existing homes, the spray foam insulation can be installed to the attic, roof line, and sub-flooring to seal in the house. It is more cost effective to leave existing interior wall insulation in place.

I have heard in the past that houses should breathe & have attic ventilation. 
Wouldn't spray-foam insulation seal my house too tight?

Your house DOES need to be ventilated, BUT most home engineers & building scientists (as well as the US Dept of Energy) advise that you seal the structure as tight as possible & provide necessary ventilation through your air conditioning & heating system. Many systems employ an "air exchanger" which pre-conditions incoming outside air to control humidity & energy efficiency. This type of design (known as an unvented attic) creates a true Thermal Envelope.

What is the R-value (insulation value) of SPF insulation?
Ultimate Spray Foam Insulation has a few different foam products of different densities. Our open-cell foam product has an R-Value of 3.5 per inch and in most applications, a house constructed with 2x4 studs will have 3.5 inches of open cell foam thus 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 product that creates an air seal. To learn more about insulation and R-values, click here.

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

How does spray-foam compare with fiberglass batts?
· Fiberglass batts will not stop air leakage. Blown-in cellulose will slow down air        leakage. Spray-foam will STOP air leakage. Spray-foam is also mold & moisture    resistant unlike fiberglass & 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 has a true R-value of 3.8 - 6.8 depending  on the density foam we use (1-inch thickness).
· Fiberglass batts can sag over time; blown-in cellulose can settle over time leaving sections of the stud cavity uninsulated. Spray-foam completely adheres to the wood studs and sheathing resulting in a permanent 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 withstand powerful winds.

I hear different opinions on open-cell vs. closed-cell foam. Which one is better & which one should I use for my property?
While Ultimate Spray Foam sprays both types of foam, the preferred choice has been closed cell foam due to its higher R-value per inch, the strength it adds to the structure, and the effectiveness of being a barrier against moisture. Although it is slightly more expensive, many owners and contractors prefer it due to these features. However, if the project has a limited budget, open cell foam is a better choice 

How does Spray Foam Insulation control moisture movement and condensation?
Most moisture damage in a building occurs when warm moist air inside the building is being exchanged with the cold dry air inside an insulation cavity. As the moisture in the air condenses, it forms dew within the insulation. Because foam insulation is an air seal, this moisture movement and condensation does not occur. It is ideal for use in climates where buildings are both heated and air conditioned because the situation is reversed in summer with moisture forming on the back of the interior vapor retarder.

FREQUENTLY ASKED QUESTIONS

Does foam insulation cause any electrical wiring overheat problems or any problems to any metal surfaces?
No, foam insulation has been thoroughly tested and is not a concern to electrical authorities nor is it corrosive to any metals whatsoever.

Does the insulation contain formaldehyde?
No.



What are the main benefits to insulating my home or business with Spray Polyurethane Foam Insulation?
· Excellent insulating properties – Outperforms pink fiberglass

· Creates a healthier and more comfortable living environment
· Bio-based and non-toxic. 

Can homeowners install Spray Foam Insulation themselves?
Unless the homeowner is willing to make a large investment in the equipment and become properly trained and certified, it is not feasible for the homeowner to install spray foam insulation. However, there are a few companies that provide small kits to spray foam in small areas. However the cost to purchase these kits can be almost three times as much compared to hiring a professional. 

What happens if the owners want to add an electrical outlet once the foam insulation is installed?
An outlet can be easily added since the spray foam insulation drills more easily than wood.

Does Spray Foam Insulation support bacteria, mold or fungal growth?
No. Our foam products offer no food value. It is an inert substance; therefore it does not support bacteria, mold or fungal growth.

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 you seal the house against: wind, dust, moisture, pollen, spores, insects, mold and allergens. Insulating your home with spray foam insulation provides a healthier, quieter, draft-free, indoor environment with no harmful emissions that can cause allergic reactions.
