Air Infiltration Through Windows And Doors

Acceptable Performance/Condition
Windows and doors shall meet the rating for weather-tightness required by the
Building Code.

Warranty
One -Year Work and Materials

Action
Ensure the window or door has been tested to meet the required weather-tightness rating. Adjust weather-stripping and/or hardware to reduce air leakage by ensuring positive contact along the weather seal.

Remarks
Doors and windows must be properly closed to ensure positive contact with
weather-stripping. Doors and windows are manufactured to meet specifications for weather-tightness and are designed to withstand reasonable wind loads. Minor air infiltration may occur during very windy conditions. Weather-stripping becomes worn with use and should be inspected and replaced by the homeowner on a regular basis.
Interior air movement caused by convection should not be confused with actual air leakage through the window and doors.
