Textile fabrics made of high-tensile coated polyester or glass fibers open up completely new dimensions in the field of building. Due to its high flexibility, the reduced surface weight that nonetheless provides an extremely high tensile strength and the light transmission ratio of the material, it is possible:
- to roof large surfaces without trusses - to design spaces flooded with light - to structurally realise completely new form - to generate attention by design and colour - to establish temporary structures and to set them up again at another location - to build in a resources-saving manner - to develop completely new building areas
The coated material is selected on the basis of project-specific requirements. Aesthetic and creative ambitions are deciding factors in the colour selection and the light transmission. The surface finish usually is a question of the financial possibilities (for example, it is possible to choose a fluor paint which distinctly improves soiling behaviour and also longevitiy). PTFE-coated glass fabric is always used when a self-cleaning effect that is as extensive as possible is requested or a non-combustible material is specified by the building authorities.
The coated material can be acted on by tension only, not by pressure. The required tensile strength results from the calculated statics.follow the link for a short digression - From the lined supporting rope to the surface Support Due to the applied pretension, the membrane itself has a support function and thus becomes a statically indispensable component of the overall structure. To give the textile roofing stability, an anticlastic design is imperative. Classical forms are the HP surface (the hyperparaboloid), the design using high points (e.g., the high-point membrane) and the saddle-shaped surface (e.g., arch membranes). These eye-catching and unconventional forms fulfill today´s requirements for an experience-oriented architecture. But efficiency also plays a role in textile building: little material expenditure, short planning phases, a quick realisation and short mounting times as well as nearly no maintenance costs make textile designs a real alternative to conventional buildings.
From an ecological view, Textile Architecture, as compared to all conventional designs for non-insulated roofings, offers the essential benefit that just 1/3 of the usual construction weight is used: a point not to be underestimated in the resources-saving use of our raw materials.
The applications of membrane buildings are highly diverse. The focus of textile building is on the following areas:
- Public event building - Tourism and catering - Park and landscape spaces - Open-air theaters - Leisure properties - Sports buildings - Entrance and walkway areas - Shopping malls and exhibition spaces - Railway stations, airports. etc.
Besides these classical applications, the membrane design also permits a realisation of various specific functional requirements: for example, heat or noise-insulating designs made of multi-layer membranes; opaque, i.e., roof designs impervious to light for specific requirements (e.g., cinemas, etc.); textile secondary structures as shading sails beneath large glass roofs; internal space architecture as a design element; demountable, temporary structures for short-term use or as touring exhibitions; etc.
