Key Product Highlights


· Excellent all-weather sealing performance

Provides a reliable waterproof and rainproof seal, effectively preventing moisture penetration and protecting the building's internal structure.

Excellent windproof performance improves building airtightness and reduces energy consumption.

· Superior weather resistance and durability

Excellent resistance to UV rays, ozone, and extreme temperatures (-50°C to +70°C), ensuring long-term exposure to the sun and rain without cracking or deterioration.

A service life of up to decades, far exceeding that of traditional materials such as PVC, significantly reducing maintenance costs.

· Excellent sound insulation and vibration absorption

The highly elastic rubber effectively absorbs and dampens vibration and noise caused by wind loads on the glass panels, enhancing building comfort.

· Precise design and easy installation

A variety of cross-sectional shapes are available (such as snap-on, beaded, and gasketed) to precisely match the profile slots of mainstream curtain wall systems.

Rational design and easy installation effectively improve on-site curtain wall construction efficiency.
