2 1. FIELD OF USE The MEDOC ventilated applied cladding procedure is destined for use on flat, vertical walls (or at angle of no more than 15 from vertical) made of concrete or stonework, or on composite walls with metallic or wooden elements on new or renovated buildings with or without windows. This cladding technique enables the construction of walls of type XIII or XIV as specified in the General Conditions of Use of External Thermal Insulation Systems (CSTB specification manual N 1833 March 1983) and the support walls must meet the requirement of paragraph 4.2. of this document, given that air-tightness is provided by the supporting wall. MEDOC SHELLS applied cladding does not contribute to the general stability of the building not to the function of load transmission, sway-bracing, shock resistance and safety which all depend on the supporting wall. 2. ATTACHMENT TO THE REGULATIONS As well as the specific particularities of the MEDOC procedure as defined in the Specifications Manual, applied cladding must be built in accordance with the General Regulation in force in relation to such, and notably: cladding.. Snow and wind rules in force in terms of determining wind stress.. Professional rules applicable to the manufacture and use of metallic.

Fastenings: invisible. 4. DESCRIPTION 4.1 Principle The MEDOC SHELLS are made of pre-lacquered, galvanized steel or stainless steel, fixed by the vertical edges then blocked in place using brackets. MEDOC SHELLS are characterized by their flat appearance and the fact that the fastening are not visible. The selected design is that of applied metallic cladding on a wall which is itself airtight and if necessary, of the wall (load-bearing wall). The definition of a wall includes reinforced concrete or stonework walls, as well as composite metal or wood walls. 4.2 Rails

5 These are made of extruded aluminium and are an integral part of the MEDOC system. They are delivered in a standard length of 6 meters and have sliding brackets into which the MEDOC SHELLS fit. The lateral parts of the rails are fixed onto the fastening lugs TG 30/10 using hex head bolts (diameter of 6) and rivets.

6 5. CORNER TRIMS MEDOC SHELLS are delivered as: 1. Pre-lacquered or Post-lacquered steel support, silicone-sprayed returns. 2. Pre-lacquered aluminium support, silicone-sprayed returns. 3. Post-lacquered aluminium support, silicone-sprayed or welded returns. 6. FIELD OF USE 6.1 Destination MEDOC SHELLS can be use for cladding the facades (vertical or sloping by a maximum of 15 from vertical) of public, private, industrial, commercial or dwelling buildings either new or renovated. In the pre-studies, particular attention should be paid to the following cases:. Building located in non-mainland France.. Façade that are higher than 10m above ground level. 6.2 Usages clauses MEDOC SHELLS must be use in accordance with the specification and requirement of the Professional Rules for the manufacture and installation of Metallic Cladding (2 nd edition, January1981). The purpose of these Specifications is to adapt and complement these Rules, bearing in mind the specificity of the products. MEDOC is designed for type XIII or XIV walls (CSTB specifications n 1833, March 1983) with ventilation airspace, according to the design and realizations of applied cladding on the façade in question. The type XIV wall implies suitable arrangements to ensure the water tightness of the various connections. 7. PARTICULAR ESTHETIC POINTS MEDOC SHELLS are designer for flat façade with or without vertical and/or horizontal indented joints. For this reason certain technical choices have been made with regard to product design. The sub frame rail on fastening lugs must be adjustable and perfectly aligned.

Particular provision: any alignment fault of the sub frame cannot be compensated for by the MEDOC SHELLS themselves. 7

8 8. CHOISE OF PRE-LACQUERED COATING IN ACCORDANCE WITH THE P 34 301 STANDARD, OR OF THE GRADE OF STAINLESS STEEL For the MEDOC SHELLS manufactured with pre-lacquered galvanized steel, in reference to the exposure defined in annex B of the standard P34 301, the following table defines the choices of coatings used: steel support, polyester support 25 microns, THD Polyester 15+20 microns, PVDF 25 microns DURANAR XL 50 to 60 microns.

THERMAL INSULATION MEDOC SHEELS have no particular thermal insulation function. If this insulation is required, it is generally ensured by semi-rigid panels or rolls of mineral wool placed beneath or between the rails leaving a ventilation airspace. In all cases, the steam-proofing function must be ensured on the warms side of the wall. On the MEDOC cladding side, a ventilation airspace of at least 2cm must be made. The insulating material must never be compressed, or esthetic problems may occur; the insulating material must no be pinched between the MEDOC SHELLS bearing frame. 10. FIRE GRADING The fire grading of the MEDOC SHELLS is M0. 11. TRIMMINGS Trimmings: pre-lacquered or stainless steel parts shaped on a folding-press and made of identical materials to the other parts.. Initial lower shells. Protruding corner shells. Retracting corner shells. Acroter cover shells. Window support parts. Parts under return face. Trimmings for opening table All these parts are made on request within manufacturing limits and are subject to an individual case-by-case study.

10 12. FASTENINGS (not supplied) MEDOC SHELLS have hidden fastenings. Concerning anti-rust protection, the fastenings must comply with the requirements of the professional rules for metallic cladding. 13. PACKAGING AND TRANSPORT 13.1 Protective film A peel-off protective film is applied to the visible face of the pre-lacquered MEDOC SHELLS. This film must be removed within 2 weeks.

11 13.2 Labelling A delivery note is affixed to each package, specifying:. customer order reference. bath reference. customer name. product type. cladding thickness. load content (number and length). grade reference of pre-lacquered steel This note is accompanied by a second note with handling and storage instructions. 13.3 Packing MEDOC SHELLS are packed on the manufacturing line. Packing consists in:. Latticed wooden case. Upper, lower and intermediate cardboard protection. Vertical storage of the shells. Retractable anti-uv surrounding film. Wooden transversal banding 13.4 Transport MEDOC SHELLS and their accessories must be transported in conditions which preserve the integrity of their characteristics (packages carefully wedged and strapped, trucks covered). 14. INSTALLATION

12 14.1 Organization The pre-studies carried out on the façade are not the responsibility of PMA or the distributing companies. PMA does not install MEDOC SHELLS. The installation of MEDOC SHELLS must be performed by companies with the required professional qualifications. 14.2 Unloading and handling Handling operations must be carried out with the particularities of the MEDOC SHELLS in mind. 15. EXTERNAL MAINTENANCE The metallic facades must be maintained in compliance with the requirement of the Professional Rules for Metallic Cladding (article 4.2.91, external maintenance). Owing to their flatness, the MEDOC SHELLS cladding is self-cleaning; however, if needs be, they can be cleaned periodically using a gentle detergent (non-bleach) following by a rinse with water. Maintenance consists in: The removal of various vegetation (moss, for example) and of any incompatible matter which may have been deposited on the surface of the cladding. The immediate repair of any localized degradation, such as incipient corrosion caused, for instance, by the stagnation or impact of foreign bodies.
