Supply and installation of a “rainscreen” and “brise-soleil” cladding, composed of a mechanical steel fixing system and
Sannini Impruneta terracotta elements, acid-washed and treated:
Primary structure constituted of vertical steel sections placed at 50 cm distances for rainscreen portions and at 100 cm
distances for brise-soleil portions. Sections are bound to the support slabs and fixed to the wall by means of special
straps and expansion bolts equipped with adjustable spacers. Fastening of the cotto elements to the structure by means
of anchors for rainscreen portions and of horizontal tubes for brise-soleil applications.
The cladding is realized with cotto element “doga flat”, manufactured out of a special clay extracted from the Impruneta
area. The elements are supplied in sizes of (l x h x t): 500x145x50 mm. They have normal kerfs on their upper and
lower edge for rainscreen applications and a “litos” surface texture; elements without kerfs and surface texture “litos”
and “arrotato” on opposite faces are used for brise-soleil application. Installation with vertical joints of approx. 6 mm.
Elements to be installed at a distance of approx. 20 cm for sunscreen systems.
Treatment: the external face of the Sannini cotto element requires acid-washing using a decalcifying acid detergent for
the removal of possible efflorescences and surface protection through the application of an impregnation on a siloxane
micro-emulsion basis. |
