What are window rubbers for?

Window rubbers, also known as window seals or weatherstrips, are a type of sealing material used to prevent air and moisture from entering a building through the spaces around windows and doors. They are typically made of flexible materials such as rubber, vinyl, or silicone and are designed to form a tight seal between the window frame and the surrounding wall.

The primary function of window rubbers is to improve energy efficiency by reducing the amount of air that can leak through the gaps around windows and doors. This can help to keep a building warm in the winter and cool in the summer, thereby reducing heating and cooling costs. In addition, window rubbers can also help to reduce noise pollution by blocking out exterior sounds.

According to the U.S. Department of Energy, air leaks around windows and doors can account for up to 25% of a building's total energy losses. Replacing old or damaged window rubbers with new, high-quality seals can help to significantly reduce these losses, improving the overall energy efficiency of the building.

In a study published by the National Renewable Energy Laboratory, researchers found that "replacing weatherstripping on windows and doors can save homeowners an average of 11% on their energy bills."

The use of window rubbers can also help to extend the lifespan of a building's windows and doors. By preventing moisture from entering the building, window rubbers can help to reduce the risk of water damage and deterioration of the window frames.

"Properly installed and maintained weatherstripping can also help to extend the life of windows and doors by reducing the amount of moisture that can enter the building and cause damage," says Tom Lawrence, a building performance expert at the Energy Trust of Oregon.

In conclusion, window rubbers play a critical role in improving the energy efficiency and overall durability of a building. By reducing air leaks and protecting against moisture damage, window rubbers can help to save homeowners money on energy bills, reduce noise pollution, and extend the life of a building's windows and doors.
