Decoding the technical terminology of membrane structures

From the Bird's Nest to the Water Cube, membrane structures are reshaping modern architectural aesthetics. But are you often confused by 'ETFE'; ' Confused by terms such as tensegrity? We will guide you into the world of membrane structures using the most accessible language

Air-inflated structure: Glossary The design of an ETFE roof typically involves creating "air cushions". Two layers of ETFE are inflated to 5 or 6 pounds per square foot by a series of inflatable devices. The low-pressure air cushion not only provides effective insulation but al

Anisotropy: Glossary The anisotropy of a membrane material refers to the fact that its physical properties and performance are not the same in all directions. If the membrane material is woven from fibers aligned in one direction, its strength and tensile properties will diff

Base Fabric: Glossary Uncoated fabric, also known as grey fabric.

Biaxial: Glossary Take along two parallel orthogonal directions, usually the main direction.

Boss Plate: Glossary The doughnut-shaped plate is connected to the steel cable ear plate to reinforce the round hole of the ear plate and allow for the insertion of thinner plates.

Lap Seam: Glossary When two pieces of membrane material are butted together, a back-adhesive strip twice the width of the weld seam is used to weld the membrane materials together. The resulting weld seam is called a parallel weld seam.

Butt Seam: Glossary Two sheets of film material are overlapped according to the specified width, and then the film material is welded. The resulting weld seam is called an overlap weld seam.

Coating: Glossary The material applied on the membrane material for waterproofing and protecting the membrane fabric.

Yarn: Glossary Many fibers are combined to form thicker weaving threads, which can be twisted together or laid parallel to each other for weaving.

Waterproof membrane/flashing: Glossary Waterproofing membranes/flashings can protect a house from water leakage issues at places where the roof slope changes, bends, and other areas prone to water infiltration. When rainwater or melted snowwater flows down the roof, the water tends to gather a
