Overview
The gap between the top of a garage door and the header is a common source of air infiltration, moisture entry, and pest intrusion. The Action Industries flexible garage door top seal closes this gap with a single flap of durable grey PVC that compresses against the door when it is in the closed position. Designed as a universal fit for both new construction and retrofit applications, this top seal mounts directly to the header jamb using self-tapping screws — with no separate retainer channel required.
The flexible PVC material provides a long-lasting, heavy-duty seal that will not warp or lose its shape under the pressure of daily door cycles. It is suitable for residential and commercial garage doors where weather protection, energy savings, and perimeter sealing are needed at the top of the door opening.
Features and Material
This top seal is manufactured from flexible PVC — a material that maintains its flexibility across a wide range of temperatures and resists cracking, splitting, and UV degradation over time. The grey color blends with most residential and commercial door frames for a clean, finished appearance. The single-flap profile creates a compressive seal against the top edge of the door panel when the door closes, blocking drafts, rain, dust, insects, and debris from entering above the door.
Installation is straightforward and does not require a retainer channel. The seal is fastened directly to the header or door jamb using self-tapping screws or compatible fasteners, making it a practical DIY or professional installation for both new builds and replacement projects. The seal can be cut to length on-site to match the exact width of the door opening.
Applications
The flexible top seal is designed for the header position on residential and commercial overhead garage doors. It is commonly used to reduce drafts, improve energy efficiency, and keep out dust, debris, and pests at the top of the door — an area that is often left unsealed or sealed with worn, ineffective weatherstripping. This product is well suited for garages, workshops, storage buildings, and light commercial facilities where maintaining a weather-tight door perimeter improves comfort and reduces heating and cooling costs.
For complete perimeter protection, this top seal can be paired with bottom seals, side jamb seals, and threshold seals from Action Industries to close every gap around the full door opening.
