Weather stripping is essential for several reasons. Firstly, it helps to regulate indoor temperature by preventing drafts. When gaps around the door allow cold air in during winter and hot air in during summer, your heating and cooling systems have to work overtime. This not only can make your home uncomfortable but also leads to higher energy bills. By installing effective weather stripping, you can maintain a consistent indoor temperature, enhancing comfort.

1. Energy Efficiency A significant amount of energy loss in homes occurs through poorly sealed windows. According to the U.S. Department of Energy, sealing windows and doors can save homeowners 10% to 20% on energy bills. By installing weather stripping, you can minimize drafts and reduce the workload on your heating and cooling systems, ultimately lowering energy consumption and costs.

Foam seals are made from dense foam tape that can be easily applied to the bottom of a door. These seals are lightweight and provide a good level of insulation.
