Explore our export-grade architectural assemblies featuring multi-barrier EPDM seals, thermal break integration, and air-tight perimeter weatherstripping engineered for commercial and residential excellence.
As a leading premier OEM/ODM weather stripping supplier and exporter, our engineering heritage is grounded in complete vertical integration—from custom compound formulation and tool dying to micro-precision extrusion and automated fusion welding.
We reject reground scrap. Every extrusion run utilizes 100% virgin EPDM, TPE, TPV, or high-density PVC polymers. This eliminates premature micro-cracking, maintaining elasticity across structural temperature swings from -40°C to +120°C.
Operating our own CNC die-making plant, we engineer co-extruded rigid/flexible profiles and sponge rubber seals in micro-increments down to 1/8-inch precision, avoiding filler trim requirements on complex facades.
Our sealing profiles are certified to surpass stringent air infiltration (ASTM E283), water resistance (ASTM E331), and acoustic insulation standards required for modern LEED and California Title 24 compliance.
Selecting the optimal elastomeric profile requires evaluating compression set recovery, acoustic attenuation, UV resistance, and durometer dynamics. Below is our comparative engineering analysis for B2B procurement specs.
| Elastomer Type | Compression Set (ASTM D395) | Acoustic Reduction (STC Delta) | UV & Ozone Resistance | Thermal Range | Primary Fenestration Application |
|---|---|---|---|---|---|
| Dense EPDM Rubber | Excellent (< 20%) | +8 to +12 dB | Superior (30+ Yrs) | -40°C to +120°C | Curtain walls, commercial aluminum sash profiles, structural glazing gaskets. |
| Co-Extruded TPE / TPV | Very Good (< 25%) | +6 to +10 dB | High (20+ Yrs) | -30°C to +100°C | Residential vinyl (PVC) replacement windows, automated fusion-welded frames. |
| Silicone Elastomer | Outstanding (< 12%) | +10 to +14 dB | Immune to UV | -60°C to +200°C | Extreme temperature architectural skylights, acoustic soundproof entries. |
| Siliconized Fin Brush Pile | N/A (Friction Barrier) | +4 to +7 dB | Good (15+ Yrs) | -20°C to +80°C | Horizontal sliding windows (XO/XOX), patio door interlocks, draft stopping. |
| Cellular EPDM Sponge | Superior (< 15%) | +9 to +13 dB | Superior (25+ Yrs) | -40°C to +110°C | Heavy-duty door sills, perimeter expansion joints, perimeter acoustic seals. |
Conventional single-durometer weatherstrips force a technical compromise between mounting rigidity and sealing flexibility. Our advanced OEM/ODM Co-Extrusion Line combines a high-rigidity base foot (Shore A 85-90) with an ultra-flexible hollow bubble or fin seal (Shore A 55-60) in a single continuous profile. Furthermore, the integration of meltable TPE slip-coatings eliminates operational friction during window cranking and sliding without degrading seal memory over 50,000 cyclic opening tests.
Architectural engineering standardizations are shifting rapidly toward net-zero building envelopes. As a strategic OEM/ODM partner, we outline the primary industry forces shaping weather seals procurement over the coming decade.
Global procurement directives now mandate lowered embodied carbon in building envelopes. Future weatherstripping specifies recycled thermoplastic vulcanizates (TPVs) and bio-attributed polymers without compromising tensile strength or compression set. OEM buyers must align with suppliers offering REACH, RoHS, and EPD (Environmental Product Declaration) verified material streams.
With Passive House standards gaining traction globally, traditional solid seals are being replaced by multi-chambered micro-hollow EPDM profiles. These internal dead-air pockets cut U-factor conductive losses through fenestration perimeters by up to 18%, playing a decisive role in achieving Energy Star V7.0 and Title 24 targets.
Window manufacturers are transitioning from manual hand-gasket installation to automated robotic insertion and inline fusion welding. OEM weatherstripping profiles must be engineered with strict dimensional stability (tolerances within ±0.05mm) and non-stretch tension cores to prevent jam-ups on automated assembly lines.
Urban density demands enhanced Sound Transmission Class (STC) and Outdoor-Indoor Transmission Class (OITC) performance. Procurement trends favor dual-durometer weatherstripping paired with asymmetric acoustic glass packages to suppress low-frequency street noise.
From custom profile concept drawing to international containerized shipping, our factory execution guarantees absolute compliance with your technical specifications and production timelines.
Send your window/door profile DWG files. Our tooling engineers optimize extrusion foot geometry, seal compression ratios, and insertion channel clearances.
Using precision wire EDM cutting, we fabricate custom steel extrusion dies within 7 to 10 working days, delivering first-article 3D samples for testing.
Continuous laser micrometer monitoring checks cross-sectional tolerances during extrusion, followed by automated anti-stretch core insertion and spooled coil packaging.
Finished weatherstripping rolls are sealed in moisture-proof polybags, boxed in heavy-duty corrugated cartons, and palletized for export container consolidation.
