Supply and installation of a “brise-soleil” cladding, composed of a mechanical steel fixing system and Sannini Impruneta
terracotta elements, acid-washed and treated:
Primary structure constituted of vertical sections in stainless steel AISI 304 placed at 100 cm distances approximately. The
sections are bound to the support slabs and fixed to the wall by means of special straps and expansion bolts equipped
with adjustable spacers and horizontal steel bars for the fastening of the cotto elements.
The cladding is realized with cotto element “quadrello”, manufactured out of a special clay extracted from the Impruneta
area. The elements are supplied in sizes of (l x h x t): 500x50x50 mm. Surface texture “arrotato” and “milled” on their
opposite faces. To be placed at a distance of approx. 12.5 cm on centre. Installation with vertical joints of about 6
mm. The cotto elements are to be installed carefully in order to avoid possible out of square placement, and to provide
compensation for any defects in the existing backup wall or reinforced concrete structures.
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. |
