Ventilated Facades GHL

The GHL ventilated façade is the system that granitech has developed to install dry large porcelain stoneware sheets with dimensions up to 3x1.5 m and thickness 6 mm. On the back of the plates is always made a safety net.
The sheets are secured to aluminum profiles by means of structural silicone made in the workshop and in a controlled atmosphere, arriving then on site as the cells of a curtainwall, ready to be mounted. On site a C-shaped graph will be inserted mechanically on the profiles placed on the back plate, necessary for mounting on the metal substructure. It is composed as follows:

  • L-anchor brackets, anchored on the existing structure of the building according to the facade layout by means of mechanical or chemical anchors.

  • Thermal spacer in shaped polypropylene, to be placed between the anchoring bracket and the wall of the building to avoid the thermal bridge

  • Black painted posts with T-section, fixed by stainless steel rivets to the L-shaped brackets described above

  • Black painted aluminium crosspieces with C-section, fixed to the uprights with stainless steel rivets

  • Non-visible fastening accessories of the plates complete with gasket

The approximate thickness of a facade realized with the GHL system is of about 19-20 cm and inside the gap it is possible to foresee the insertion of a layer of insulation, whose characteristics are defined by the thermotechnical.
