Foam Insulation Questions and Answers
Q. Does this product have an adverse effect on our shingles?
A. Absolutely not. What causes shingles to curl is when the heat beneath the shingles exceeds the heat on the exterior side. With our product, it eliminates all the conduction heat from transferring into the attic space. Once foamed, your roof deck will heat and cool at a more even pace, allowing more life out of the shingles.
Q. Will foam bond to all substrates?
A. Yes. Foam bonds to all substrates including metal, concrete, wood, glass and plastic. The only thing foam does not like is moisture. We have to be sure that all materials are dry before foam is applied.
Q. Is foam a new insulator on the market?
A. No. Foam has been manufactured and used for approximately 50 years. In its early stages, foam had formaldehyde and other harmful products in its makeup. Today, foam is a green product, has zero ozone depletion and is the healthiest insulation on the market. Foam was originally used where temperatures were extreme in the summer or winter months. The southeastern region is now using foam because our utility bills are constantly on the rise, and it makes for a much more comfortable, quiet and less dusty home.
Q. How much does this insulation cost compared to fiberglass or cellulose?
A. Foam is usually three to four times more than traditional insulation. However, through energy savings alone, it usually pays for itself in six to eight years on a new construction home, and even less on an existing home. Not only do you save money every month on utility bills, you have a much more comfortable home.
Q. We have always been told a house has to breathe. How does it do so when it’s completely sealed up?
A. Yes, your house does have to breathe, but it does so through the HVAC unit. This stands for heating, ventilation and air conditioning. Your home does not breathe through cracks and crevices that let exterior air in and conditioned air out. This causes your home to be drafty, inefficient and uncomfortable.
