Flexible polyvinyl chloride (PVC) extrusions designed to attach to the bottom edge of a garage door are intended to create a seal against the floor. These components, often clear or black, are typically sold in rolls or pre-cut lengths and are affixed using fasteners or adhesives. Their function is to close the gap between the door and the ground, preventing ingress of elements and pests.
The utility of this sealing method extends to improved energy efficiency by limiting drafts, protection against water damage by diverting rainwater, and enhanced security by obstructing visual access into the garage. Historically, alternative materials like rubber were used, but PVC offers advantages in terms of durability, weather resistance, and cost-effectiveness. The implementation of this system contributes to a more controlled and secure environment within the garage space.
