Frequently Asked Questions
Question: What makes Spray Foam Insulation so effective?
Answer: Spray Foam Insulation is so effective because it is applied as a liquid and expands 100 times its original liquid size in seconds. As it expands, it conforms and fills each cavity, crevasse and void to create a sealed thermal envelope. Spray Foam Insulation creates a highly-efficient seal against air infiltration, the number one source of energy loss in a structure. This innovative insulation adheres to any clean, dry surface and will not sag, settle or Foam Insulation also is an inert substance and will not support mold growth, insects or rodents. It also does not breakdown over time, so it creates a sealed interior that blocks harmful outside irritants.
Question: What is the difference between open-cell and closed-cell foams?
Answer: Both open-cell and closed-cell foams stop the movement of air and slow down the transfer of heat. Open-cell foam products are generally not considered vapor retarders. In climate zones 6-8 a vapor retarder system may be required on the warm side of the insulation relative to the design of the wall or ceiling system. Open-cell foam should never be used for exterior applications. Open-cell foams are more cost effective per unit of R-value than closed-cell foams but do not provide the structural contribution to a building that closed-cell foams do.Closed-cell foams, on the other hand, have low vapor permeance due to their cell structure. These foams, depending on thickness, may be considered a vapor retarder but not a vapor barrier. Closed-cell foams also have a high compressive strength which allows them to be used for exterior applications.
Question: How does Spray Foam Insulation save consumers money?
Answer: While the initial cost of installing Spray Foam Insulation may be higher than traditional insulation, the savings in monthly utility bills outweighs the extra cost and results in a positive cash flow. When paired with other responsible building components, Spray Foam Insulation can reduce monthly energy bills by up to 50%. As an example, using Spray Foam Insulation may increase your monthly mortgage by $15, but decrease your monthly utility bills by $65, providing a net savings of $50 each month. Because Spray Foam Insulation creates a continuous, sealed thermal envelope around your home or structure, in many cases, you also can save additional money by reducing the required size of the HVAC (heating and air conditioning) unit.
Question: How does Spray Foam Insulation control indoor air quality and comfort?
Answer: Spray Foam Insulation provides a healthier, draft-free, indoor environment. Because Spray Foam Insulation expands to fill every cavity, crevasse and void, it provides a sealed thermal envelope that does not sag or settle over time. This improves indoor air quality by blocking harmful outside irritants such as mold, pollen and other allergens and offers an alternative to fibrous particulates which are attributed to many traditional insulation sealed envelope gives the HVAC system full control over the amount and filtration of fresh air coming into the structure in addition to reducing drafts and temperature differences throughout the building. A sealed envelope can also reduce the amount of airborne noise pollution entering the home.
Question: How long does Spray Foam Insulation last?
Answer: Indefinitely. As an inert, thermoset plastic, Spray Foam Insulation will maintain its properties throughout the life of the building.
Question: Does Spray Foam Insulation adhere to metal or wood studs?
Answer: Spray Foam Insulation adheres well to almost any material, especially wood and steel studs, which are commonly found in residential and commercial construction.
Question: Can Spray Foam Insulation be sprayed over electrical wiring?
Answer: Spray Foam insulation does not pose any issues with electrical wiring as long as the electrical wiring is installed per National Electric Code. Any overheating issues with Spray Foam insulation in regards to wiring would be directly related to improper installation of the circuit or the size of the wiring. Polyurethane foam is chemically compatible with electrical wiring plastic.
Question: Does Spray Foam Qualify for any Tax Credits?
Answer: Yes Spray Foam Insulation can qualify for federal and state tax credits. The qualifications for home repairs and upgrades are always changing from year to year.
