Building Curtain Wall and Window Sealing Strips

For building envelopes Changfeng supplies EPDM sealing strips for curtain walls, aluminum and uPVC doors and windows, and expansion joints between wall panels. Profiles include glazing gaskets for single and insulating glass, weather seals with dense or sponge bulbs, and expansion-joint covers that absorb thermal and structural movement. The EPDM compound is modified for high salt-spray and strong UV environments, keeping elasticity across wide temperature ranges without hardening, so gaskets stay watertight and airtight over years of service. Sections are designed to the aluminium system's groove drawings, and tooling for custom profiles is developed in-house. Colour options include black, grey and custom RAL tones.
