Product Description

- Commodity name: Curtain Wall PVC Composite Strip E3776
Curtain wall PVC composite strips are multi-functional sealing and thermal-insulation components specifically designed for architectural curtain walls, hidden-frame curtain walls, exposed-frame curtain walls, and glass curtain walls. Made from rigid PVC as the base material and integrally molded with a composite elastic soft rubber strip, they combine structural strength with sealing elasticity, making them widely used for installation and fixation, waterproof sealing, and thermal insulation buffering between glass and aluminum profiles.

Product Introduction

Curtain wall PVC composite strips are multi-functional, sealant and thermal-insulation components specifically designed for architectural curtain walls, hidden-frame curtain walls, exposed-frame curtain walls, and glass curtain walls. Made from rigid PVC as the base material and integrally molded with a composite elastic soft rubber strip, they combine structural strength with sealing elasticity, making them widely used for installation and fixation, waterproof sealing, and thermal insulation buffering between glass and aluminum profiles.

The product tightly fills the gaps between curtain wall glass and the frame, effectively preventing rainwater and windblown sand from infiltrating and thereby enhancing the overall water tightness, air tightness, sound insulation, and thermal insulation performance of the curtain wall. The rigid component provides stable support and precise positioning, while the elastic component cushions the compressive vibrations between the glass and the profile, preventing edge chipping and stress-induced cracking, and simultaneously reducing thermal conductivity to achieve an effective thermal break.

This product exhibits excellent aging resistance, superior high- and low-temperature performance, UV resistance, and outstanding dimensional stability—remaining resistant to deformation and yellowing. It offers precise dimensions and a tight, seamless fit, can be freely cut to site-specific lengths, and is installed via snap-in or pressure-strip methods, ensuring convenient and secure construction. It is ideally suited for new curtain-wall installations as well as sealing repairs and replacements on existing curtain walls, serving as a safe, reliable, and universally compatible sealant component within curtain-wall systems.

Anti-theft Door Seal Strip E3208

The security door seal is a specialized sealing component installed between the door frame and the door leaf. It is typically manufactured in one piece from high-quality, environmentally friendly, weather-resistant materials such as EPDM rubber, silicone, or flexible PVC. Through a scientifically engineered foamed or solid structure, it provides effective cushioning and a tight seal when the door is closed, effectively filling even the smallest gaps between the door leaf and the frame. This delivers multiple practical benefits, including wind resistance, dustproofing, sound insulation, thermal retention, impact protection, insect prevention, draft elimination, and odor barrier.

Garage Door Double-Leaf Seal Strip E3225

The garage door dual-wing weatherstripping is a high-performance sealing component specifically designed for the top and sides of garage doors. It is manufactured via integral extrusion from premium EPDM rubber or weather-resistant PVC, featuring a core dual-wing seal structure paired with dedicated aluminum alloy or uPVC mounting clips. When installed at the junction between the garage door and the door frame, the dual wings are compressed during closure to form a tight, seamless fit, creating a double-layered sealing barrier that effectively blocks wind, rain, dust, insects, and noise, thereby enhancing the garage’s airtightness, thermal insulation, and overall comfort.
