Types of Tensile Membrane Structures
PTFE, or polytetrafluoroethylene, is a Teflon®-coated woven fiberglass membrane that is extremely durable, weather resistant and a highly sustainable building material for roofing applications. PTFE fiberglass membranes can be installed in climates ranging from the frigid arctic to the scorching desert heat with a project life in some cases exceeding 30 years.
ETFE (Ethylene Tetrafluoroethylene) can be applied in multiple ways such as single, double or triple layered tensile architecture applications. The material is durable, highly transparent and very lightweight in comparison to glass structures.
PVC, or polyvinyl chloride, is available as a woven or non-woven material. PVC membrane fabric canopies are a cost-effective alternative to traditional roofing or façade systems and can be produced in a multitude of colors to coordinate with individual building project needs.
Insulated Tensioned Membrane
Tensotherm™ is a composite system comprised of a PTFE fiberglass membrane exterior skin, a thin translucent insulation blanket embedded with aerogel, and a thinner and lighter acoustic or vapor barrier interior liner.
PTFE-coated, high translucency (ePTFE) fabric membrane is a dynamic tensile material unmatched for its aesthetics and durability, which is a woven, non-flammable material that uses 100 percent fluoropolymer coating and can offer up to 40 percent light transmission (versus just 13 percent with PVC), eliminating glare to allow broad illumination throughout a given interior space.
