Etfe Roof Construction Detail

Etfe or ethylene tetrafluoroethylene is an exciting addition to the selection of membrane materials fabritec structures offers.

Etfe roof construction detail.

It is a highly transparent extruded film applied either as a single layer membrane or as a multilayer pneumatically inflated cushion. Etfe foil roofs can be supplied as a single layer membrane supported by a cable net system or as a series of pneumatic cushions made up of between two and five layers of etfe. Etfe spreaded in architecture in the last 2 dcades thanks to the characteristics of lightness transparency and economy compared to glass roofs or facades. 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 two to five layers of etfe.

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 building frame. 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 foil is a plastic polymer related to teflon and is created by taking the polymer resin and extruding it into a thin film. This in turn reduces heating costs.

In case of a greenhouse etfe roofs can trap warm air inside the building to improve its thermal properties. Etfe is a manmade fluoropolymer which stands for ethylene tetrafluoroethylene which has attained its position as an efficient architectural material. Etfe foil can be useful for the building s thermal design. 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.
