Sealing the gap between a patio door and its frame is essential for energy efficiency and comfortable indoor environments. This is typically achieved with flexible materials like rubber, foam, felt, or vinyl. These materials, fitted around the door’s edges, effectively block drafts, moisture, and insects.
Effective perimeter seals significantly reduce energy loss by preventing heated or cooled air from escaping and outside air from infiltrating. This translates to lower energy bills and a smaller carbon footprint. Furthermore, a well-sealed door minimizes noise pollution from the outdoors and protects against water damage that can lead to mold and structural issues. This practice has become increasingly important with modern construction focusing on tighter building envelopes for enhanced energy performance.
