Air Leaks and Air Sealing
Air leakage can result in 25% of heat loss in newly constructed homes and up to 50% in older homes causing discomfort and increasing utility bills
Benefits of Air Sealing
Improved Comfort - Drafts are often the result of unsealed cracks and holes in the building envelope. Air sealing homes results in fewer drafts and added comfort.
Lower Utility Bills - Air leakage wastes energy used to heat and cool your home. An average home has the equivalent of 2 open windows just in cracks between building materials and unsealed penetrations through the roof and floor.
Improved Indoor Air Quality - A tighter building envelope reduces the amount of humidity, dust, pollen, and pests that can enter the home helping improve indoor air quality.
Increased Durability - Reducing air leakage helps minimize moisture problems and increases the home's durability. When warm air leaks through a home's floors, walls, and attic, it can come in contact with cooler surfaces where condensation can occur. Moisture that occurs in these construction assemblies encourages mold growth, ruins insulation, and even compromises the structural elements of the home.
Air sealing measures that we typically install include the following:
- Windows: Caulk window frames and trim; weather strip at top and bottom of window
- Exterior Doors: Install weather stripping around door; caulking around door frame
- Attic Hatch: Install weather strip and insulate
- Electrical Outlets: Install gaskets around outlets; fill gaps with expanding foam
- Exhaust Fans: Seal inside enclosure with aluminum tape
- Recessed Lighting Fixtures: Seal edges of fixtures located on the second floor that penetrate attic space
- Chimney/Fireplace: Seal any gaps around the fireplace chimney, furnace fluepipe and vent pipes that extend through the attic
- Dryer Vent: Install/replace dampers in exhaust ducts to prevent outside air from entering house
- Trim: Caulk baseboards
- Space Pack Air Conditioning Ducts: Install caps for ducts in the winter
- Sealing Air Ducts: Seal with fiber-reinforced mastic
- Basement Sill Plate: Seal gaps where the basement ceiling meets the foundation wall
- Pipes and conduits: Seal around any pipes, conduits, wires, or cables that pass between floors.
