Ptfe Roof Details

Etfe foil can be useful for the building s thermal design.

Ptfe roof details. Tensioned membrane roofing fabric roofing birdair inc. Eptfe 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. Etfe roofs offer excellent sustainability. This tensile fabric roof material has a life span of over 25 years and is manufactured in accordance to standards such as astm e 108 and e 84.

Single skin ptfe roofs typically weigh 1 5kg per m2 and thermal sandwich roofs typically weigh 3 5kg per m2. During scientific tests of its solar properties it was discovered that ptfe fiberglass membranes reflect as much as 73 percent of the sun s energy while holding just seven percent on its exterior surface. Etfe is effectively the high strength version of the other three in this group often featuring slightly diminished capacities in other fields by comparison. Tensile membranes can be manufactured to virtually any size and shape up to 1600m2 in a single panel.

Ptfe or polytetrafluoroethylene is a teflon coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements. The width of the membrane is 4000mm at present it is out of look in the world. Ptfe has excellent weather temperature and chemical resistance in addition to its durability and strength. However noise and rain suppression.

Useful comparison tables of ptfe against fep pfa and etfe can be found on dupont s website listing the mechanical thermal chemical electrical and vapour properties of each side by side. Ptfe roofs do not need to be cleaned internally. The woven fiberglass gives ptfe coated glass fiber its mechanical strength and providing the membrane with maximum flexibility. Ptfe varies in translucency from 7 to 15 and reflects between 68 75 of incident sunlight.

Sustainability is one of the main arguments for etfe roofs. The latter is a major selling point for foil for traditionally noisy areas like indoor sports halls and swimming pools the echoing noise now simply escapes through the roof however when noise exclusion is required eg airports external traffic noise and heavy rain and hail etfe currently struggles. From the extrusion of the etfe foil through to transport and installation the light weight of the material reduces the co 2 footprint significantly.
