Installation

MGO Board ®

HANDLING AND

STORAGE: Always store indoors, the material must not be exposed to water or high humidity levels. During transportation the boards should be placed in upright position (edgeways) and should be handled carefully to avoid damaging the edges. To cut, start by cutting the surface reinforcement mesh on one side with a cutter, fold the board to break it and then cut the reinforcement mesh on the other side.

ENVIRONMENTAL

CONDITIONS: Before installation the boards must be acclimatized to the temperature and humidity level of the environment. The temperature should not be below 5°C. When applying the filler and finishing, the temperature must be between 5° and 40°C with relative humidity below 80% during application and for 48 hours following completion. Before assembly ensure that the boards are perfectly dry; do not install the boards if damp.

SUPPORT FRAME:

All the wall, double wall and false ceiling profiles must be constructed as set forth by UNI EN 14195 standard in cold laminated steel hot coated with aluminium and zinc or zinc and magnesium alloy as set forth by UNI EN 10215 standard. The thickness of the profiles should be between 0.6 and 1.00 mm and must be positioned at a centre distance varying from 400 to 600 mm; the structure must be dimensioned according to the static requirements of the project and wind pressure. All fixing elements, accessories, nuts and bolts should be resistant to aggressive environments, namely they should be made of stainless steel or have a coating ensuring salt spray test resistance of 1,000 hours. WATER-PROOF TRANSPIRING BARRIER: MGO Boards are resistant to water but are not waterproof; if condensate forms in the air space therefore, the boards may absorb humidity from the inner side (which is not treated with a finishing coat). To prevent this, an anti-condensate barrier consisting of a waterproofing vapour-transpiring membrane should be placed between the structure and MGO Boards. If the board is installed vertically, the membrane should be fixed temporarily to the structure from the bottom to top, positioning the sheets horizontally and overlapping the edges of the layers by at least 10 cm. If the boards are laid horizontally, the edges of the membrane should in any case be overlapped by at least 10 cm.
