Using Cushion On Roof

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.

Using cushion on roof.

This plenum pipe is connected to each individual cushion by small feeder hose pipes. Working closely with the client and their design team the etfe cushion roof was designed to include a guttering system which collects rainwater to be re used for irrigating the plant life. The cushion roof system requires a constant supply of pressurised air that is distributed by an inflation unit. Elevated etfe cushion is simplified as a rectangular opening on the roof in the calculation model.

The spaces inbetween are inflated with air. The inflation unit is connected to a through a large plenum pipe that is secured around the perimeter edge of the cushion roof. 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. Foam closure strips for metal roofing are specially formulated with unique wave designs for premium sealing of metal roofing panels.

This provides both insulation k values from 2 94 to 1 47 and strength. The area of each opening is 20 m2. Of course cushion and cable net systems remain your best choice for large clear span and more fluid shapes but for traditional roof shapes using traditional support systems texo gives you all the advantages of etfe but without the risks associated with fabric welds and inflation systems and for a much lower cost. An innovative product from buitink technology is the air cushion roof made of etfe foil.

This system could generate electricity for system use and provide a way of collecting thermal energy as air inside etfe cushion roof could be heated. Made of cushioning durable and water resistant foam materials metal roof foam closure strips can be easily fabricated to any custom. They can also be used as cushion seals for polycarbonate roofing panels. In this roofing video bob schmidt shows you how to use the foam padding from a sofa cushion to say secure and not fall while doing roof repairs.

These roofs are produced in two three or four separate layers of foil. 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. However pv high temperature could have serious effects on structural etfe foil as mechanical properties of etfe foil decrease noticeably with temperature increase 21 22 23.
