Etfe foil roofs can be supplied as a single layer membrane supported by a cable net system or commonly as a series of pneumatic cushions made up of between two and five layers of a modified copolymer called ethylene tetra flouro ethylene etfe.
Etfe single membrane roof problems.
The installed structure at radclyffe school is proof that it is possible to create an etfe roof using the simplest of shapes even with minimal curvature but without losing any of.
Etfe or ethylene tetrafluoroethylene is an exciting addition to the selection of membrane materials fabritec structures offers.
Features and benefits of etfe membrane.
Don t be a victim of etfe roofing problems airsculpt prides itself on our expertise and problem solving approach to design and engineering within tensile architecture.
The material has good uv stability as well as chemical and heat resistance.
This applies whether the waterproofing is a polymeric single ply membrane a reinforced bitumen membrane or another type listed in bs 6229 2018 the code of practice for flat roofs with continuously supported flexible waterproof coverings.
Etfe cushion systems incorporate a pneumatic system to maintain air between two or three layers of film.
Same pervious light effect with glass but more security more light more flexible more creative in style and energy saving effect also has long life expectancy good self cleaning depend on anti adhesive surface properties.
Etfe membrane is made of ethylene and tetrafluoroethylene.
Whether it is a single layer or in cushion forms etfe foil systems are supported in an aluminium extrusion at the perimeter which in turn is supported by the main.
In addition to leaks this can cause premature problems with the roof membrane and may void the guarantee.
Use etfe in a double triple or more layered system to form an etfe membrane if you need a structure with greater thermal insulation and structural stability.
It is a highly transparent extruded film applied either as a single layer membrane or as a multilayer pneumatically inflated cushion.
Single ply etfe has massive and somewhat untapped potential for creating interesting and dynamic structures in a range of settings and with a variety of effects.
These are then supported by a lightweight structure creating inflated cushions.

The recommended minimum fall for a flat roof is 1 80 0 72.
The etfe copolymer is extruded into thin films or foils which are used to form either a single.
Care notes abuse of the finished roof as one of the nine most common problems plaguing single ply systems stating heavy construction traffic can cause scrapes cuts in the membrane and damage to the underlying substrate.
