Large gap-filling seals designed for doors offer a robust solution to significant air leakage. These products, often made from materials like foam, rubber, or felt, provide a substantial barrier against drafts, moisture, and pests when standard-sized options prove insufficient. For instance, older homes with settling foundations or doors warped over time might require this type of robust sealing solution.
Effective sealing around door frames significantly improves energy efficiency by minimizing heat transfer between interior and exterior spaces. This leads to lower energy consumption and reduced utility costs. Furthermore, enhanced sealing improves sound insulation and reduces noise infiltration. Historically, methods for sealing gaps have evolved from simple fabric strips to precisely engineered materials, reflecting an increasing understanding of building science and the importance of airtight construction.
