Waterproofing Technology in ETFE Membrane Structure

The key to ETFE membrane structure is to solve its waterproof problem. ETFE film is ethylene-tetrafluoroethylene copolymer, high chemical inertia, is a "non-stick" fluorine material.

In the design of roofing buildings, due to the non-adhesive ETFE film and almost no chemical reaction with other substances, the traditional pressing glue process of the film structure will cause the glue and the film to be non-stick, and the water resistance and waterproof effect will not be achieved. ETFE membrane structure buildings on the market that are constructed with a similar PVC membrane installation process usually have water leakage problems.

Individual construction manufacturers have specially customized aluminum alloy bracket fixed support system, which has the functions of film buckle fixation, two silicone extrusion water resistance, water seepage active drainage and so on. ETFE film structure is complex and delicate, simple and beautiful appearance, aluminum alloy material and ensure its durable quality.

The ETFE membrane structure roof, which uses aluminum alloy brackets to fix the support system, has almost no rainwater leakage and perfectly solves the waterproof problem. This lies in the wisdom of the designer, not only relying on the waterproof characteristics of the material itself, but also taking into account the overall design rationality, greatly avoiding the possibility of water seepage.

The combination of ETFE membrane structure and aluminum alloy bracket fixed support system can make a beautiful building with good waterproof effect.

ETFE membrane structure is a new type of building material, which has the advantages of light quality, light transmission, weather resistance and corrosion resistance. It has a wide range of application prospects in the fields of transparent roof, curtain wall and long-span construction. With the progress of technology and the accumulation of application experience, ETFE membrane structure will play an increasingly important role in architectural design.
