Effective sealing around a garage door is essential for maintaining a comfortable indoor environment and protecting stored belongings. This is achieved through various types of perimeter seals, including bottom seals (often made of rubber or vinyl), threshold seals, and top and side seals. These components work together to block drafts, prevent water intrusion, and keep out pests and debris.
Proper sealing offers significant advantages. A well-sealed garage minimizes energy loss by preventing conditioned air from escaping and outside air from entering. This leads to lower energy bills and reduced strain on heating and cooling systems. Furthermore, it safeguards against moisture damage that can warp wood, corrode metal, and promote mold growth. Historically, simple felt or wood strips were used, but modern materials and designs offer superior performance and durability. The evolution of these sealing methods reflects the increasing demand for energy efficiency and protection against the elements.
