Innovation in cotto cladding.
Description of specification items
Curtain wall realized with “cuspide“
Supply and installation of a “curtain wall” cladding, composed of a mechanical steel / extruded raw aluminum fixing system and Sannini Impruneta terracotta elements, acid-washed and treated.
Secondary structure constituted of vertical sections of stainless steel / extruded raw aluminum placed at 150 cm distance 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 horizontal omega-shaped bar of extruded raw aluminum.
The cladding is realized with Cotto element “Cuspide”, manufactured out of a special clay extracted from the Impruneta area. The elements are supplied in sizes of (l x h x t) 500 x 164 x 95 mm, having two faces with superficial finish "Litos" and one face "Honed" to be installed with vertical joints of about 6 mm and inter-axis of 12,5 cm. The Cotto elements have to be applied carefully in order to avoid possible out of square placement and to provide compensation for any tolerance from the existing backup wall or reinforced concrete structure, leaving a gap of about 8/10 cm between the back face of the cladding elements and the support wall.
Color
Natural Litos
Extruded terracotta fired without any working processes on its surface.
Slightly striped finish obtained through the natural coloration of the salts moving towards the surface during the drying process, prior to firing.
Tobacco Litos
Extruded terracotta with smooth “litos” surface and fullbody tobacco colouration.
The coloration is being obtained by mixing a composition of oxides into the clay, allowing a uniform colour penetration and distribution. All physical and mechanical characteristics remain unaltered.
Champagne Litos
Extruded terracotta with smooth “litos” surface and fullbody champagne colouration.
The coloration is being obtained by mixing a composition of oxides into the clay, allowing a uniform colour penetration and distribution. All physical and mechanical characteristics remain unaltered.
