This waterproof Door And Window Sealing Strip is designed to help improve the sealing of aluminum door and window systems against external environmental exposure. The flexible rubber structure creates a barrier along compatible frame gaps and helps reduce the possibility of water, wind, dust, and outside air passing through the sealed area.

The profile can be compressed between contacting surfaces while maintaining flexibility during normal door and window movement. Its cushioning characteristics also help reduce direct contact between rigid aluminum components, which can be useful for sliding and hinged systems.

Different sealing profiles are available for various aluminum extrusion structures. Groove-inserted designs can be fitted into dedicated channels, while adhesive-backed versions provide an alternative installation method for suitable surfaces. Hollow profiles can offer additional flexibility where compression is required.

Applications include aluminum windows, exterior doors, sliding doors, balcony enclosures, commercial entrances, and architectural partition systems. The sealing strip can be used in both new construction and maintenance projects.

Manufacturers and wholesalers can request customized sizes, colors, profile configurations, packaging, and branding. For projects with special aluminum extrusion requirements, customers can provide profile samples or technical drawings so the sealing geometry can be matched to the installation position.

• Waterproof & Airtight Performance: Tightly seals gaps to prevent rain leakage and air infiltration, improve window energy efficiency.
• Sound Insulation Function: Absorb wind noise and buffer metal collision, reduce indoor and outdoor sound transmission.
• Excellent Elasticity & Compression Recovery: Will not permanently deform after repeated compression, maintain stable sealing effect.
• Dust & Insect Proof: Block dust, debris and small insects from entering the room through frame gaps.
• Custom Options Available: Multiple cross-section shapes, colors and lengths, OEM custom extrusion for bulk orders.

• Broken bridge thermal insulation aluminum system windows and doors
• Residential and commercial building door & window projects
• Casement windows, sliding windows, inward tilt-turn windows
• Window factory supporting rubber gasket accessories

Poor sealing is the main cause of window water leakage, air leakage and noise problems. Our EPDM door and window sealing strip has stable elastic performance in all climates. It forms a continuous soft seal between sash and frame, reduces energy consumption, improves indoor comfort and extends the service life of the whole window system.
