Tensile Membrane Dome Structures

A tension membrane structure is fabric structures supported by compression or bending elements, like beams, masts, or compression rings. They're often used as a roof as they are attractive, maintain great natural light, economical and can span large distances.Tensile structure is the term usually used to refer to the construction of roofs using a membrane held in place on steel cables. Their main characteristics are the way in which they work under stress tensile, their ease of pre-fabrication, their ability to cover large spans, and their malleability.For external Use there are two main choices PVC (Poly Vinyl Chloride) coated polyester cloth and PTFE (Poly Tetra Fluro Ethlene) (Teflon) coated glass cloth. The PVC coating contains additives that include UV stabilisers, fire retardants, colouring and antifungicides.
