Zephir Installation

Technical Guide on how to install Zephir Evolution

Fixing System

The cladding system based on single-skin terracotta components, including longitudinal bars on the back enabling them to be suspended on horizontal rails, supported on a vertical framework secured to the main structure and behind where insulation may be fitted.

There are two versions of the horizontal rail, for a narrow horizontal joint (5 mm, standard rail, or prominent (16 mm, rail XI) (for close terracotta tolerances).

There are various accessories not supplied by TERREAL (in italics in the diagrams): thermal insulation, mastic, fixing brackets, wooden or steel structural verticals, steel or PVC profiles for skirts and various finishes, various screws and fixing anchors

Installation

Installation of Zéphir® must comply with that envisioned by CSTB Technical approval no. 2/08-1330. Positioned horizontally with an average theoretical spacing of 25 or 30 cm (recommended spacing indicated on the pallet, for fi tting with a standard rail). The rails are fixed to a vertical framework leaving a 1 to 2 cm air gap between the ends of the rails on each row. Installation on a concrete or rendered masonry substrate of the vertical structure made of wooden batten or steel profiles, must comply with the rules contained in CSTB specifications nos. 3316/3422/3585 (steel structure) – or nos. 3194/3586 (steel structure, flanged design), with a 2 cm minimum air gap. Fixing these profiles using brackets spaced between 30 and 90 cm apart, depending on the mechanical strength requirement, is generally staggered and spaced according to a technical study taking into account the mechanical strength and thermal requirements (strength of the anchors, wind, and seismicity).


A steel structure based on “Z” profiles, fixed directly to the support wall may also be used. Terracotta products are fitted from bottom to top, suspended on the upper rail by their upper bar and locked with two dots of mastic (type Sikafl ex® Pro 11 FC) on the lower bar on the upper part of the lower rail.
The addition of intermediate rails in addition to the usual rails, may increase resistance to wind (up to classifi cation V4) and to impacts (up to class Q3).
At critical points, Zéphir® may be easily cut vertically (12 cm minimum) or horizontally (using the intermediate hooking bars for fixing), using a diamond-tipped saw lubricated with water.
