Texlon etfe technology combines between two and five layers of etfe foil to form air pressure stabilised cladding panels or a single layer system. In a proper air system 2 blowers one operational and one stand by and an air dryer are available.

Refer to the details. Connection details etfe cushions are fixed to the aluminum profiles assembled to the carrying structure by a special elevating apparatus.

Flexibility was a desirable property because the displacements may significantly vary among the buildings supporting the etfe atrium roof during wind and seismic loading.

The springs in the cable spring system allow large differential displacements without exerting large reactions on the buildings. The number of layers used in a panel depends on project specific requirements for structural and thermal performance. Include roof pitch roof geometry slope length and climatic factors such as heavy snowfall or rainfall. All the standard connections given in the green book may be classified as nominally pinned based on the strength requirements together with extensive experience of details used in practice.

Whenever possible begin trim installation at the downwind end of the roof farthest away from the source of prevailing winds to al low flashing laps to face away from wind driven rain.

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. Class c is the lowest class of non fragile assembly and particularly if engineered to pass the test criteria may be close to the boundary between fragile and non fragile. 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. 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.
