Air Infiltration Through Windows and Doors
Acceptable Performance/Condition Windows and doors shall meet the rating for weathertightness required by the Building Code. Warranty One-Year Work and Materials Action Ensure the window or door has been tested to meet the required weathertightness rating. Adjust weatherstripping 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 weatherstripping. Doors and windows are manufactured to meet specifications for weathertightness and are designed to withstand reasonable wind loads. Minor air infiltration may occur during very windy conditions. Weatherstripping 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. |
