Testing for loss or gain. Air leakage is expensive!
Air LeakageAir Leakage occurs when outside air enters and conditioned air leaves your house uncontrollably through cracks and openings. This is referred to as Infiltration and Exhalation. It is unwise to rely on air leakage for ventilation. During cold or windy weather, too much air may enter the house. When it's warm and less windy, not enough air may enter, which results in poor indoor air quality. Air leakage also contributes to moisture problems that can affect occupant's health and the structure's durability. AIR SEALING CORRECTLY IS IMPORTANT. SOME SIMPLE THINGS SHOULD BE UNDERSTOOD:
- Insulation is not an Air Barrier - Insulation provides a thermal barrier not an air barrier. Air can still go in, around and through insulation.
- You need to "Seal it Tight and Ventilate it Right" - Homes need the proper amount of ventilation for the occupants health and the durability of the home.
