Installation Piterak® Slim installations must comply with CSTB Technical Approval no. 2/10-1403. Fitting to a concrete or masonry support covered with a vertical framework must comply with the rules in CSTB specifi cations nos. 3194/3586 (metal framework, with restrictions on use), including the allowance of an air gap of a minimum of 2 cm. The framework is made up of special
aluminum profi les, fi tted to standard fi xing brackets or special yokes. The brackets are fitted beforehand in a staggered pattern on either side of the profile. The layout of these fixings, not supplied by us, must be as required by the project’s engineer of record taking into account thermal and mechanical requirements (strength of the anchors, wind, and applicable seismic conditions).
Piterak® Slim products are fitted from the bottom upwards; the bottom of each Piterak® Slim product is located into pre-fitted bottom clips, and then pushed back against the profi les. Before screwing the upper clips into the profile, using two self-tapping 5.5 mm stainless steel pan head screws, the clips must be height adjusted in accordance with the spacing gauge and offset sideways against the positioning lug on the side of the support surface in question. The clips grip the top of the product with a spring effect but allow a sideways adjustment to ensure an even 10 to 20 mm vertical joint. Uniformity of the horizontal joint, 12 mm (±2 mm),
is ensured by use of the spacing gauge. Piterak® Slim may easily be cut vertically at critical points (approx. 20 cm minimum), or horizontally (at the edge of a cell) using a diamond-tipped saw, lubricated with water.
