Weatherstripping plays a key role in improving the comfort and energy efficiency of your home. These perimeter seals are strategically placed around the edges of operable exterior doors and windows to keep air out. Preventing air leakage, dramatically reduces heat loss around these openings making the home more comfortable and less costly to heat or cool. Before the use of these materials, considerable amounts of expensive conditioned air would be lost from the home even when the windows and doors were tightly shut.
Most weather seal material is made of flexible rubber, plastic or felt. Some more expensive interlocking versions are made for custom entry doors. These are made of brass strips that lock firmly into grooves in the door jamb. When the door or window frame is closed, these strips engage to tightly seal off the gaps. Thresholds at the base of exterior doors are considered part of the weatherstrip system.
Most manufactured windows and exterior doors come with weather seals pre-installed from the factory. If yours doesn’t have it, or if it has been damaged or lost, it is easily replaced.
- Checking for air leaks and updating your weatherstripping can be one of the most cost-effective upgrades you can do.
- Inspect the gaps around your doors and windows and if you can see daylight or feel moving air f you do, it is likely because you have a leak that can be stopped with new weatherstripping.
