Sunscreen Cladding

Quadrello

Description of specification items

Sunscreen cladding realized with “quadrello”

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.

Color

Natural Brushed

Extruded terracotta with rustic surface, obtained through working the element’s surface with steel brushes prior to firing. The intense colour of this tile is due to the removal of surface salts during the brushing process.

Tobacco Brushed

Extruded terracotta with rustic surface “arrotato” and fullbody tobacco colouration.
The coloration is being obtained by mixing a composition of oxides into the clay, allowing a uniform colour penetration

Champagne Brushed

Extruded terracotta with rustic surface “arrotato” 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.

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
