In use since the 1960 s it s a single ply synthetic rubber.
Etfe single membrane roof.
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.
A guide to design.
Etfe roofs can be designed with a flat or curved canopy allow brilliant light transparency over 95 and require minimal foundations or supporting steel framework.
Individuality in design and function.
The material has good uv stability as well as chemical and heat resistance.
Designed engineered and supplied in two formats etfe roof structures can be supplied as a single layer membrane supported by a cable net structure or with an etfe cushion system.
It is a highly transparent extruded film applied either as a single layer membrane or as a multilayer pneumatically inflated cushion.
Etfe cushion systems incorporate a pneumatic system to maintain air between two or three layers of film.
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 comes in both 45 mils and 60 mils thicknesses though typically you ll find it in 60 mils thicknesses at most home improvement stores.
These are then supported by a lightweight structure creating inflated cushions.
This is 3 of the weight compared to a 6 6 laminated glass panel.
Etfe whether used as a single layer membrane tensioned between structural framework or as pneumatically prestressed air cushions the versatility allows it to adapt to deformations or unique shapes and designs of any given roofing system structure.
Etfe has a density of 1 75gr m which equals to 780g m for a single layer of etfe skin.
Etfe or ethylene tetrafluoroethylene is an exciting addition to the selection of membrane materials fabritec structures offers.
Generously sized rooms without supports minimal use of materials and environmentally responsible construction methods are all possible through the use of etfe membranes in addition due to continuous improvement of the material itself buildings and structures utilizing our films are setting new aesthetic and technical standards.
Reduction of the self weight of the cladding material allowed using slimmer steel sections at the roof.
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.
The g value of an etfe roof can be reduced to as little as 0 48 for a 2 layer system with a.
