Introduction

If it looks like the future, that’s because it is.

A relative newcomer in the construction materials scene, membrane architecture has made a stunning debut. No other construction material gives designers and architects the same flexibility to push the creative envelope while working with a strong, energy-efficient and aesthetically remarkable product. Architectural membrane is, in fact, a nomenclature that describes a variety of products. Dyneon, a 3M company, contributes elements to two of the most prominent styles. The first is a glass fabric coated with Dyneon™ PTFE and then with either Dyneon ™ PFA or Dyneon™ FEP to provide additional sealing and weldability. The second form of membrane is a clear film made from a fluorothermoplastic like Dyneon™ ET 6235 (ETFE). Each membrane product shares common strengths while possessing enough unique attributes to extend the spectrum of design even further. Translucent or transparent, flexible and dazzling, designs including membrane materials have opened up new perspectives in architecture. From small awnings to vast stadiums, membranes easily inspire new forms. Self-supporting curved surfaces are a reality. Light is incorporated more thoroughly than ever before. Strength and fire-resistance bring a functional yet striking style to a diverse range of projects and functions. The examples in this brochure depict what has already been achieved by using membranes made with Dyneon PTFE, Dyneon PFA, Dyneon FEP and Dyneon ETFE. And these are just the beginning. With Dyneon™ Fluoropolymers, the possibilities are endless.

Paradise found The Eden Project A combination of environmental education and botanic attractions, the Eden Project in Cornwall, England showcases biomes and plants from around the world. Fascinated by the earth beneath their feet, Eden’s visitors have also responded enthusiastically to the roof over their heads; the spectacular geodesic dome structure is the world’s largest self-supporting roof construction. To build a structure of that size, the designers sought a material that would be cost-effective, while meeting several functional requirements. The roof needed to be lightweight and highly transparent to allow the plants their sunlight. Designers turned to transparent membrane cushions fabricated out of a versatile film made from Dyneon™ ETFE. Its flexibility allowed it to transform into the geodesic form, and retain its insulating capacity. Plants thrived because the 100 µm film made with Dyneon ETFE enables up to 88% of UV rays and over 90% of visible light to come through. And, in addition to the scientific benefits, the roof will remain impressive looking, because the film is practically self-cleaning, needing just a good rain to wash off accumulated dirt. With such impressive architecture and flora, it’s no surprise that most of Eden’s visitors don’t want to leave.

Fabric and coating: Verseidag-Indutex GmbH, Krefeld, Germany

The hotel is designed to resemble a sail, and a 168-meter (551 ft) membrane façade supports that vivid imagery. During the daytime the white, practically self-cleaning façade shines brilliantly, appearing to billow out over the sea, letting light into the hotel’s luxurious atrium. At night, multi-colored lights create an iridescent shimmer. The demands of building in the Arabian climate meant that the designers needed a material that was flexible and light, yet could accommodate the temperature differences between day and night, strong winds, and earthquake safety codes. Glass fabric coated with Dyneon™ PTFE and Dyneon™ Fluorothermoplastics met those requirements. Each membrane is up to 10-12% translucent, and has a high UV reflection power so the atrium behind can be filled with light, yet remain cool. The membranes can sustain broad span widths, even in the faces of high wind pressure. It’s a design that luxury deserves.

A sky without limits Munich Airport Center As the connecting link between Munich’s busy airport terminals, the Munich Airport Center has the character of a central market place. It’s a rare public area that contains places to meet, eat and shop, yet feels cleaner and friendlier than your average suburban mall (not to mention your average airport terminal). That friendly feeling is impressive, considering some of the challenges the architects originally faced. The roof needed to withstand extreme winds, meet strict fire safety requirements, and stay weather resistant. Examining their options, the architectural teams found that glass fabric coated with Dyneon™ PTFE and Dyneon™ PFA or Dyneon™ FEP, interspersed with steel and glass sections best fit their needs.

Sea shell by the sea shore Prienavera Leisure Center and Adventure Pool Perched on the shores of Lake Chiem in the Bavarian Alps, the Prienavera Leisure Center emphasizes its aquatic theme with a complimentary use of membrane design. A transparent membrane roof, built in the shape of a shell, stretches over the interior adventure swimming pool and out onto the lake, linking the interior with the natural world around the resort. For the shell-shaped roof, the architects used highly transparent membranes made with flame resistant Dyneon™ ETFE. They expanded the capabilities of this membrane film by literally printing a series of dots on it, providing an effective UV filter while still creating a sunny indoor experience. The membrane system also provides a simple means of insulation. Forget about oysters – this shell is a pearl in itself.

World Class Pusan Dome When soccer’s World Cup 2002 kicked off, one of the largest and most spectacular stadiums in Korea opened its doors – the Pusan Dome. Designed as a multi-function stadium, and covering a total area of 93,000 square meters (1,001,000 sq ft) the Pusan Dome has already proved its mettle by playing host to the world. The dome was inspired by Pusan’s coastal location. The stadium roof rises above the city like a white sea urchin, linking the stadium to an adjacent sports complex. Despite its size, the light membrane material makes the roof appear delicate. In the planning stage, the architects were faced with a number of challenges. Struggling with rocky soil, humidity, and safety requirements, the architects also needed to restrict the weight of the roof material, and select something that provided adequate noise reduction. The solution was glass fabric coated with Dyneon™ PTFE and Dyneon™ Fluorothermoplastic. With its low weight, humidity and flame resistance,

A landmark for tomorrow National Stadium Main Bowl Complex

Taking a cue from the Pusan Dome, membrane architecture plays a significant role in the design of Nigeria’s new National Stadium, the location of 2003’s "All African Games." Designed as a link between traditional regional architecture and the most modern construction technology, a membrane roof made up of 36 separate fields stretches over the 30,000 m2 (323,000 sq ft) stadium area and 60,000 seats. The Dyneon™ PTFE and Dyneon™ Fluorothermoplastic coated glass fabric sections that make up the roof are translucent, but at the same time protect against powerful UV radiation, rain and weather conditions. The membrane is so effective at blocking out UV rays that it will also reduce the build-up of heat inside the stadium, even on the sunniest days. Decade-long durability and positive acoustic properties also made this membrane the first choice for Nigeria’s newest national landmark. Talk about home-field advantage.

Honoring the past, welcoming the future Courtyard of Honor, Berlin Federal Chancellery Visiting state dignitaries at the Berlin Federal Chancellery are welcomed by a mix of architecture that honors its history while embracing a futuristic design. Representing "the future" here, is a translucent membrane roof that stretches over the Courtyard of Honor and acts as a counterpoint to the weighty architecture of the chancellery. The membrane awning links form and function perfectly. It fits in with the prestigious nature of the square without taking focus away from the buildings, and it offers the guests of honor protection from wind and weather. The translucent nature of the material, glass fabric coated with Dyneon™ PTFE and Dyneon™ Fluorothermoplastic, allows the light to be conveyed with subtle differences – perfect in a location likely to be visited by photographers and filmmakers. As a self-supporting construction, the large 240 m2 (2,600 sq ft) membrane field is resistant to an enormous amount of force. And, due to its durability, it will welcome honored guests for many years to come.
