A door brush seal is a continuous strip brush installed along the top, sides, bottom, or meeting edge of a moving door. The flexible filaments maintain light contact with the door or surrounding frame while allowing the door to open and close.
Door brush seals help reduce the entry of dust, drafts, light, leaves, insects, and other loose debris around uneven or moving gaps. They are commonly used where a rigid sealing edge may create excessive drag or cannot follow a corrugated or irregular surface.
A brush seal is not automatically airtight, watertight, soundproof, or fire-rated. These performance requirements must be evaluated as part of the complete door and building-envelope design.
Door Types That Use Brush Seals
Garage and Sectional Doors
Top, side, and bottom brush seals help cover variable gaps around commercial garage doors, service-bay doors, warehouse doors, and sectional overhead doors.
Roller Shutters and Coiling Doors
Strip brush seals provide flexible contact around shutter guides, frames, headers, and other moving interfaces.
Sliding and Barn Doors
Brush seals can follow the top, sides, meeting edges, or bottom of sliding doors where movement and uneven floor gaps make rigid seals difficult to use.
Commercial and Industrial Doors
Custom door brush seals can be produced for warehouses, factories, loading areas, equipment buildings, and other large door openings.
Large and Hangar Doors
Drawing-defined strip brush seals can be reviewed for large sliding, folding, or overhead door systems.

Filament & Performance Specifications
Nylon, PP, and PBT filament options are available. The material is selected according to the customer’s door movement, contact, moisture, temperature, and outdoor-use requirements.
UV-stabilized, weather-resistant, or flame-retardant material grades can be supplied when specified. These properties apply only to the approved material specification and should not be presented as a certified performance rating for the complete door seal unless supporting test data is available.
Match the Brush Seal to the Door Movement
The brush should maintain continuous contact without creating unnecessary resistance as the door moves. The correct configuration depends on whether the brush contacts a flat panel, a corrugated curtain, a side guide, an uneven floor, or the edge of a sliding door.
Brush seals are frequently installed at the top and sides of rolling or sectional doors, while the bottom position may also require a rubber astragal, threshold, or drainage solution. Brush and rubber seals should be selected according to the actual gap and environmental requirement rather than treated as interchangeable products.
