Air leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. During cold or windy weather, too much air may enter the house. When it’s warmer and less windy, not enough air may enter, which can result in poor indoor air quality.
Too much air movement significantly reduces performance of the building envelope and is a major contributor to the energy consumption in a building.
Air leakage also contributes to moisture problems that can affect occupants’ health and the structure’s durability. Condensation within or on walls can create several problems such as rotting of wood, corrosion of metal beams, permanent damage to insulation and mold throughout the building.
Sealing cracks and openings lowers drafts and cold spots, improving comfort for all occupants. By reducing the amount of air that leaks in and out of your home, heating and cooling costs are cut down, durability is improved and a healthier indoor environment is created.
More than 30% of a home’s energy loss is through the walls, floors and roof due to air leakage.
Each home’s unique design mean’s each has different needs and energy efficient insulation provides both thermal comfort and air-sealing to stop your home leaking thousands of dollars annually.
