A small groove or notch cut into a door or doorjamb provides a snug fit for compressible sealing material. This precise channel, typically made with a saw or router, accommodates various types of weather stripping, creating a tight barrier against drafts, moisture, and pests. For example, a precisely sized channel in a doorjamb can house a specialized bulb-shaped seal, maximizing its effectiveness.
Properly sized and positioned channels are essential for optimal weather seal performance. These channels allow for a secure fit, preventing the seal from shifting or detaching over time. This airtight seal contributes to energy efficiency by minimizing air leakage, resulting in lower heating and cooling costs. Historically, such accommodations for sealing materials have evolved alongside advancements in building materials and construction techniques, reflecting a growing understanding of building science and energy conservation.
