The 3 layered etfe inflatable system weighs around 2 3 kg m2 in average with the connection aluminums.

Texlon etfe technology combines between two and five layers of etfe foil to form air pressure stabilised cladding panels or a single layer system.

The number of layers used in a panel depends on project specific requirements for structural and thermal performance.
The system requires a dedicated and secure power supply consisting of two 240v 13 amp electrical connections as the etfe foil roof is a live system the cushions are permanently linked to the air inflation unit to ensure the pressure is maintained.
Which usually support etfe roofs.
Etfe foil cushion systems are certified as class c non fragile roof assembly in accordance with acr m 001 200 test for fragility of roofing assemblies.
This feature enables covering long spans by a lightweight carrying system.
Air flow is supplied to the cushions at a specified pressure from the ventilation pipes connected from inside or outside the elevating apparatus and the cushion takes the predicted inflation form.
Etfe ethylene tetrafluoroethylene foils can be transparent coloured or printed.

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.
The springs in the cable spring system allow large differential displacements without exerting large reactions on the buildings.
Connection details etfe cushions are fixed to the aluminum profiles assembled to the carrying structure by a special elevating apparatus.
The control system can be read out on line through telephone connection or internet.
In a proper air system 2 blowers one operational and one stand by and an air dryer are available.
An etfe air cushion roof is always connected to an air blowing system to control air pressure in the cushion.
Therefore when considered with carrying infrastructure it provides much more economic solutions.
Our control systems are equipped with remote display.

Located near to the etfe cushion system internally or externally.
Flexibility was a desirable property because the displacements may significantly vary among the buildings supporting the etfe atrium roof during wind and seismic loading.
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.
