Attic Air Sealing Tips
During the summer, an unsealed attic lets warm air pour into a home, forcing an AC to work overtime and driving up energy costs. Air sealing the attic, paired with insulation and duct sealing, can reduce energy bills by 15% on average and keep homes comfortable and cool.
When performing attic air spray foam insulation, it is important to draft a sketch of the area to identify areas that are likely to leak or have voids. This can save time, making the process more efficient. Using a vapor barrier, such as drywall tape or foil HVAC wrap, is also an essential step to prevent moisture condensation.
A well-sealed attic helps control indoor air quality by prohibiting dusty outdoor air from entering living spaces and reducing indoor allergens. In addition, a sealed attic helps prevent moist drywall and wood framing from damaging cellulose or fiberglass insulation.
In addition to identifying and plugging air leaks, a professional contractor will check the ductwork to ensure that the conditioned air from the attic can travel into the living space. This includes looking for a rusty or damaged ductwork, holes, tears, or detachments. A contractor may also check naturally venting combustion appliances to ensure that they are not blocking or backdrafting into the attic space.
Once the attic is air-sealed, it is important to protect the newly-sealed area from rodent entry. GE Pest Block Foam or Multipurpose Foam can be used to fill gaps around pipes, wires, and attic kneewalls that a rodent could enter through. These products are odorless, water-resistant, and designed to flex with seasonal movement.
