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 roof details.
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.
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.
Ptfe roofs do not need to be cleaned internally.
Ptfe fiberglass is additionally energy star and cool roof rating council certified.
The woven fiberglass gives ptfe coated glass fiber its mechanical strength and providing the membrane with maximum flexibility.
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.
The membrane is made up from seam welded sections which.
The width of the membrane is 4000mm at present it is out of look in the world.
From the extrusion of the etfe foil through to transport and installation the light weight of the material reduces the co 2 footprint significantly.
Etfe is effectively the high strength version of the other three in this group often featuring slightly diminished capacities in other fields by comparison.

However noise and rain suppression.
Ptfe or polytetrafluoroethylene is a teflon coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements.
Our ptfe coated fabric architectural membrane ptfe architectural membrane ptfe architectural membrane is light highly tensile strength peel strength and fine pliability the premium properties of cleaning light transmittance reflectivity tensile structures provide up to 20 years or more of reliable service.
Etfe roofs offer excellent sustainability.
Tensile membranes can be manufactured to virtually any size and shape up to 1600m2 in a single panel.
Ptfe has excellent weather temperature and chemical resistance in addition to its durability and strength.
Single skin ptfe roofs typically weigh 1 5kg per m2 and thermal sandwich roofs typically weigh 3 5kg per m2.
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.
