Shamal® is a long-length terracotta sunscreen (up to 1290 mm, 1350 mm grid) with an aircraft wing cross-section.
It is available in two widths (140 and 200 mm), ten colours and two finishes (smooth and sanded).
Shamal® ‘Plus’ is the “system” version of this product. Shamal® is accompanied by an environmental and health data sheet for high environmental quality projects.
Shamal® ‘Plus’ 14 and 20 is delivered assembled by TERREAL, comprising Shamal® terracotta product with pre-fitted metal and rubber components ready for its final fitting on to a vertical framework.
The framework is also available from TERREAL. The sunscreen is made secure by two stainless steel rods passing through it (retaining any debris from breakages) and assembly is completed by connecting the metal components to each other, at the interface between cast aluminum plates and prepunched aluminum profiles.

> Shade provided: the fi ne “blade” shape of Shamal® 14 and 20 makes it highly effective as a protection against sun. The support profi les available with a range of fi tting centres, are well suited to Shamal® 14 (200 mm centres on SHAP03 and SHAP04) and Shamal® 20 (300 mm centres on profi les SHAP05 and SHAP06). The blades may be tilted before fi tting but care should be taken when doing so, to avoid greatly reducing the amount of free heat/light entering in winter.3 > Impact resistance: Shamal® has demonstrated its resistance to impacts, giving it a Q3 classifi cation, when tilted to 30, 45 and 60° (performs less well at 0°). Its use on a balcony without a guard rail in between is not recommended; where appropriate, it is advisable to carry out a test in situ, where this type of installation is envisaged. > Wind resistance: wind tunnel tests (CSTB test centre) have proven that the system is perfectly strong in various confi gurations, similar to those encountered in a building, up to wind speeds of 244 k.p.h. (cyclone conditions). > Earthquake resistance: during seismic tests at the CSTB, the Shamal® system demonstrated its resistance to seismic tremors, including in the event of a structure being forced into a parallelogram shape.
The Shamal® fixing system comprises the Shamal® ‘Plus’ fittings and vertical structure rack system profiles. These are intended for the very simple fitting of Shamal® ‘Plus’, whatever the desired orientation around its axis and for two different fitting possibilities (200 or 300 mm centres).
Fixing is permanent and does not allow the sunscreen to be tilted at will; the system does, however hold the sunscreen together and retain the pieces in the event of accidental breakage.
Shamal® framework profiles are available in 2.995 m lengths for the ‘standard’ and ‘edge’ versions (see diagrams), with punching on two sides or one only, to accept the Shamal® ‘Plus’ positioning plates. Each profile is supplied with a cover profile, clipped to the front, before all the sunscreens are secured to it with screws.
There are various accessories not supplied by TERREAL (in italics in the diagrams): screws, fixing brackets, anchors.
The installation of Shamal® ‘Plus’ on site is greatly simplified by the use of the system’s rack profiles: these are fixed to the support by brackets or yokes; their position must be adjusted in relation to each other and they must be plumb, as is customary when fitting cladding framework.
This ensures that the blades will be horizontal when installed.
Once the framework is adjusted and fixed permanently, each Shamal ‘Plus’ sunscreen must be pushed over the ends of the plates, using the opposite punchings on two adjacent profiles.
A type of “cradle” permanently accepts the centring boss on the plates but still allows them to be turned around their axis, according to an angle either set to the markings on the plate (0, 30, 45 or 60°), or to another angle within this range.
The finishing of the front of the profile must be done by clipping and then screwing the “cover” on to the support profile, before each Shamal® ‘Plus’ sunscreen is permanently fixed by screwing the plates against the wall of the profile (at least one self-tapping, stainless steel screw per plate): the angle of the sunscreen is then permanently fixed.

> Fixed in the upper and lower parts of the bay by brackets on the support, the Shamal® vertical framework profiles support the Shamal® ‘Plus’ sunscreens, adjusted to the same bare exterior as the Piterak® cladding of the same colour. The edge profile, not punched on the cladding side, itself acts as a trim for the bay reveal.
