Compression seals designed for specific door models manufactured by Pella Corporation prevent air and water infiltration around the perimeter of an entryway. These components, typically made of durable materials like rubber or silicone, are essential for maintaining energy efficiency and protecting interiors from the elements. For instance, a properly installed seal can significantly reduce drafts around a patio door.
Effective perimeter sealing plays a crucial role in reducing energy consumption by minimizing heat transfer between the interior and exterior of a building. This leads to lower heating and cooling costs and contributes to a more comfortable indoor environment. Furthermore, these seals help prevent moisture damage by blocking rainwater and snowmelt, thus protecting against wood rot, mold growth, and other issues that can compromise structural integrity. Over time, materials and designs have evolved to improve performance and longevity, reflecting advancements in building science and material technology.
