Our Rubber Door And Window Sealing Strip is engineered to provide a flexible sealing interface for aluminum window profiles and door systems. The rubber construction offers excellent elasticity, allowing the profile to accommodate movement between the frame and contacting surface. This makes it ideal for applications where doors or windows are frequently opened and closed.

Installed around suitable aluminum profiles, the sealing strip effectively reduces gaps that may allow wind, dust, drafts, and outside air to pass through. The flexible material also serves as a buffer between hard surfaces, helping to reduce vibration and contact noise during operation. Depending on the selected profile design, the hollow internal structure can provide additional compression and recovery characteristics.

• Premium EPDM Rubber Material: Excellent aging resistance, ozone resistance, UV resistance, and stable elasticity for long service life
• Waterproof & Airtight Performance: Tightly seals gaps to prevent rain leakage and air infiltration, improving window energy efficiency
• Sound Insulation Function: Absorbs wind noise and buffers metal collision, reducing indoor and outdoor sound transmission
• Excellent Elasticity & Compression Recovery: Maintains stable sealing effect without permanent deformation after repeated compression
• Dust & Insect Proof: Blocks dust, debris, and small insects from entering the room through frame gaps
• Custom Options Available: Multiple cross-section shapes, colors, and lengths with 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 maintains 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 entire window system.
