Ducts are used to distribute conditioned air throughout a house however about 20% of that air is lost due to leaks. Air sealing your home and attic with Spray Foam can reduce lost air and fix air leaks once and for all.
Understanding Air Leaks
Air leakage occurs when outside air enters and conditioned air leaves your home uncontrollably. Points of leakage usually occur through cracks and openings in your home structure, attic and ducts. These openings commonly occur as a house settles over time. These cracks often become leakage points and need to be taken care of in order to save energy. You may already know where some leaks occur in your home, such as an under-the-door draft. However, you need to find the less obvious gaps to really fix the problem. We can help you determine where and how your home is losing air and fix the problem by air sealing. A complete energy assessment can also help determine areas in your home that need more insulation.
Sealing the Attic Floor
In this application foam is sprayed directly to the underside of the roof effectively sealing off and insulating the entire attic space from any air infiltration.
An un-sealed attic can become approximately 130-degrees in the summer. Making your air-conditioning and vent-ductwork have to work in severe conditions.
Sealing the underside of the roof deck, insulates the attic space from the extreme heat that once radiated thorough the hot shingles sheathing and roof. The severe temperatures no longer exist and, the attic now becomes a “conditioned” space, just as comfortable as any other room in the home.
A roof sealed and insulated with spray foam reduces energy several ways. Energy loss from ducts located in the attic is essentially eliminated, excess moisture isn’t pulled into the attic, Infiltration through the ceiling is reduced, and the attic temperature is lower.
Sealing the Crawl Space
If the crawl space in your home is not fully sealed, there is a strong likelihood that contaminated air, earth gases, mold, rodents, and more can penetrate your living space. Air leaks during the summer, warm humid air can flow around openings and create condensation, mold and decay problems in the floor system.
Spray foam insulation installed between your floor joists in your crawl space is the only material that will create an effective thermal barrier from obstructions such as wiring and plumbing. Voids and open spaces can be completely filled by air sealing, resulting in a complete, essentially uniform barrier on the floor.

- Indoor Air QualityPrevent pollutants from entering ducts and circulating through your home.
- Improve ComfortSealing ducts can help with rooms that are too cold in the winter or too hot in the summer.
- Improve SafetyGas appliances release combustion gases (like carbon monoxide) through their ventilation systems. Leaky ductwork in your heating and cooling system may cause “backdrafting,” where these gases are drawn back into the living space.
- Save MoneyA typical duct system loses about 20% of conditioned air through leaks, holes, and poorly connected ducts.
