Additionally, ETFE foil materials from three dif ferent producers and two. So compared with glass, ETFE is an advantage when it comes to trans-parency and weight of the structure. But this was no ordinary ETFE cushion roof; whilst the Tropical House provides a living environment of over 650 plants, it’s also home to frogs, birds and even a few sloths – not our usual clients! The roof is made up. The desired Solar Heat Gain Coefficient (SHGC) value can be achieved by printing a special reflective ink, known as. A main use for it is in construction of air-filled “pillows” supported by frames (note: ETFE pillows are made from between 2 and 5 layers with thermal resistance comparable to glass, and with a maximum size of 4-5 metres (12-16 feet). A positive operating pressure of 200 to 600 Pa (4 to 12 psf) inside the cushion is used to support external loads such as wind and snow. Due to its lightness, ETFE can be used where large expanses of glass would be too heavy, providing light and. 6% strain the sag is 0. Until now, several research studies have been published.
