Why Choose Our Door and Window Sealing Strip?
We can customize sealing strip cross-sections, dimensions, hardness, and shapes according to your window profiles, hardware systems, or technical drawings. This allows the sealing strips to fit different door and window structures more accurately.
Before mass production, our team can check your profile samples or drawings to confirm the sealing strip structure and installation position. This helps identify compatibility issues in advance and reduces fitting problems during installation.
Our production system supports both standard sealing strips and customized project orders. Multiple specifications can be produced and supplied together, helping distributors, contractors, and door and window manufacturers simplify procurement for large projects.

Your Trusted Manufacturer of Door and Window Sealing Strips
Verixor has been deeply involved in the door and window sealing strip industry for many years, serving project purchasers, decoration contractors, hardware wholesalers, and door and window manufacturers.
Low-quality sealing strips can shrink, harden, crack, or fall off over time, leaving gaps between the frame and sash. This can lead to water and air leakage, while deformed strips may put excessive pressure on the hardware and cause the transmission lock to jam.
Our sealing strips use a specially developed rubber foam formulation that has undergone repeated opening and closing tests to balance softness and resilience. The strips maintain proper compression without putting excessive pressure on the hardware, helping prevent deformation and locking problems while improving the water and airtightness of doors and windows.
This helps reduce maintenance caused by frequent seal replacement and hardware problems.

Virgin EPDM for Longer-Lasting Sealing
Our door and window sealing strips are made from virgin EPDM environmentally friendly raw materials, helping reduce common problems such as aging, shrinkage, and cracking. By focusing on material quality at the source, the sealing strips maintain better flexibility and sealing performance during long-term use. This helps reduce gaps between the frame and sash, lowering the need for frequent replacement and maintenance.


Precise 11.5mm Fit for Better Sealing
Our door and window sealing strips are precisely designed for 11.5mm standard frame-sash gap grooves, ensuring a close fit with the complete hardware system. When the sash closes, the strip is evenly compressed and fills the gap, helping prevent water seepage and air leakage caused by gaps between the frame and sash.

Ordinary sealing strips can only seal against water damage and cannot replace fire protection. Our fireproof window sealing strips are made with specially customized EPDM adhesive, which is flame-retardant. They are also matched with our fireproof hinges, fireproof transmission locks, and window closers – a complete set of hardware that not only seals against water damage but also meets fire safety inspection standards.
We have ample stock of all types of window and door sealing strips, including thermal break, inward-opening, tilt-and-turn, outward-opening, and sliding types. These can be shipped together in a single order, saving customers the hassle of placing multiple orders and receiving goods multiple times.
Inward-opening and tilt-and-turn windows, outward-opening windows, sliding windows, and diamond screens all correspond to different series of our hardware. The sealing strip cross-section and snap-fit are different. Before shipment, they are packaged by model. You can select the hardware according to the window type.
The sealing strips are normally packed according to specification and model to prevent mixing during transportation and installation. For bulk orders, different models can be separately labeled and packed according to the customer’s requirements. We can also discuss packaging methods based on container loading, order quantity, and project delivery arrangements.
Yes. Samples can be provided for customers who need to verify the cross-section, flexibility, fitting, or compatibility with their existing profiles.
