Curtain Wall Glass

Poliedra-Sky Glass 130 and 180 is the result of the cooperation between Metra and Web Glass, it is the architectural and functional evolution of the curtain walls. Glass is the main component and separation element between the interior; with a constant thermal condition, and the external environment with continuous weather variability. 
The system Poliedra-Sky Glass interacts with the main functions, both physical-technical (thermal and acoustic insulation, solar radiation control, safety, etc.) and ecological (energy saving, environmental impact, etc.) giving at the same time a pleasant sensation of transparency or semi-transparency, in relation to a specified purpose and a precise architectural integration.

Application

The system Poliedra-Sky Glass is a curtain wall with point load fixing of the glass pane to the structure lying behind made of extruded aluminium bearing mullions. The system enables the fabrication of whole glass surfaces for the pleasure of a direct contact with the external environment. Its application is suitable both for vertical and horizontal surfaces for the realization of transparent coverings, even with polygonal shapes. Also, the system enables the fabrication of particular works such as parapets, exhibition stands, and structures with utilisation of monolithic stratified glazing or insulating glazing.

Main Features

The bearing elements are formed by mullions with IPE or tubular ellipsoidal geometrical shape, with deepness variable in function of the static requirements. The glazing modules are fixed to the aluminium structure by specific anchoring accessories made also of aluminium. These anchoring accessories are fixed in four points placed next to the junction of the corners of the glazing modules, by means of the stainless steel connections, with 130 mm (Poliedra Sky Glass 130) or 180 mm (Poliedra Sky Glass 180) horizontal and vertical interaxis. In case of specific static requirements, additional anchoring accessories are provided, fitted half-way at the long sides of the glazing sheets and aligned with those fitted at the corners.
