Door and window weatherstrip seals prevent air infiltration and water intrusion at frame perimeters. Stock 34 OEM-compatible weatherstrip profiles for hinged doors, sliding glass units, and window frames across residential and light commercial applications.
Weatherstrip Selection by Door Type and Frame Configuration
Weatherstrip degradation causes thermal loss, moisture penetration, and air leakage—critical failure points in door and window assemblies. Correct profile identification requires frame depth, material compatibility (vinyl, rubber, silicone), and compression set specifications. Replace worn seals during retrofit, new construction, or maintenance cycles to restore thermal and acoustic performance.
Identify the Right Profile for Your Frame Assembly
Weatherstrip sits in grooves or adheres to frame edges to seal gaps between sash/door panel and frame. Measure frame width, depth, and compression distance; verify OEM part number against your door brand and model. Profile geometry—U-channel, bulb, or pile configurations—must match original specifications for proper seal and operational clearance.
Sizing and Material Specifications
Weatherstrip durability depends on material grade (vinyl vs. silicone), compression set rating, and UV/temperature range. Common widths range 1/2" to 1" with varying depths for frame cavity fit. Verify lengths required per frame (top, sides, bottom runs differ); order slightly over measured length to avoid field cuts that compromise seal integrity.
