One of the main reasons to use under door air stoppers is to enhance a home's energy efficiency. Drafts can significantly impact indoor temperatures, causing heating and cooling systems to work harder to maintain a consistent climate. According to the U.S. Department of Energy, nearly 30% of the energy used for heating and cooling homes can be lost due to air leaks. By effectively sealing the gaps, under door air stoppers can help homeowners save money on their energy bills and reduce their carbon footprint.
