Description

Supply and installation of a “curtain wall” 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 50 cm distances approximately. 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 anchors for the fastening of the cotto elements.
The cladding is realized with cotto element “piastra 25 mm”, manufactured out of a special clay extracted from the Impruneta area. The elements are supplied in sizes of (l x h x t): 500x250x25 mm. They have normal kerfs on their upper and lower edges and an “arrotato” surface texture. Installation with vertical and horizontal joints of about 6mm. 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 structure, leaving a space of about 8/10 cm between the back face of the cladding elements and the support wall.
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.
