Translucent, smoothly curved and light - these characteristics make tensile and membrane architecture one of the most fascinating disciplines today. Frei Otto paved the way and it is impossible to imagine contemporary architecture without these suspended forms and structures. Tensile and membrane architecture continue to revolutionise the design and construction of large span roofs.

The most classic example of a textile roof so-called “four-point-sail”, a symmetric saddle shape membrane roof with four anchoring points.


The “language” of membrane is versatile and one-of-a-kind. Transparent ETFE foils have significantly increased the possibilities to use membrane roofs. Transparent ETFE-foil cushion roofs are capable of achieving excellent thermal insulation and are making tensile and membrane architecture “mainstream”.
