With the development of ETFE membrane structure, the thermal insulation performance of long-span tensioned membrane structure has been greatly improved. Translucent, daylighting and heat insulation flexible exterior walls and roofs have become a reality, and ETFE membrane is the prospect of membrane structure curtain walls. The curtain wall and roof of ETFE film in Munich Football League, Germany, has a roof area of 38,000m2 and a curtain wall area of 26,000m2, and the tensile strength of ETFF film is 52N/ mm

Allianz Stadium is the home of two football teams in Munich. Therefore, the diamond-shaped ETFE surface film provides an ingenious design. The two kinds of airbags under the membrane will emit red and blue light when different teams play at home, and will be white when they are not in team games.

Use case:

The Eden Project is a plant center, which is a series of interconnected huge ETFE membrane greenhouses. It is located in Beauville/Horst, Cornwall, England. The architectural design is Nicholas Grimshaw ET Partners, and the structural design is Anthony John Orver Elap. The completion date is 20065438.

Because the Garden of Eden is designed as a light structure and adopts a new material ETFE, it can effectively support the huge greenhouse. The advantages of ETFE are firmness, lightness, high light transmittance and better heat insulation effect than ordinary glass. The basic unit of ETFE is a regular hexagon, which is not only conducive to the flexible design of arch building modeling, but also has strong terrain adaptability and does not need to change the original terrain on a large scale.
