| Trewall is an integral covering system for buildings with ventilated facades; it includes metal modular elements which, anchored and suspended to the slab, seal and cover completely the primary structure while functioning as a supporting system for the elements composing the facade. Since the Trewall system does not require cross beams, joints and sleeves, it can withstand all the tensions which the supporting structures are subject to without the risk of joint "beating" The working loads weigh only on the vertical rods of the ribbed structure which is suspended to the individual slabs of the building. This kind of system allows the anchoring and inserting of all the connection elements on the special ribs of the supporting structure for any kind of facade covering (marble, terracotta paving slabs, metal panels, plaster bearing sheets, etc.). The Designer has maximum freedom and flexibility in selecting the materials since the external cladding only has an aesthetic function. Given its mechanical nature, the system forms two air cavities: a ventilated external one which in addition to eliminating possible penetrating water, reduces wind pressure and depression, condensate and solar irradiation on the supporting structure; the second internal cavity forms a static air chamber which, together with a continuous thermal insulating separator, contributes to thermal and acoustic improvement of the entire facade thus increasing energy saving. The resistance to water,air and fire penetration of theTrewall system is not obtained through sealing washers (which generally have a shorter life when compared to the other facade elements), but through a total metal coat which mechanically excludes water and air at the maximum levels required by the current regulation. |
