At the base of the wall, a minimum 30mm clear cavity must be provided behind the Cedral Click planks with a 10mm opening at the base, head and at the windows, doors or cills. Assembly must start at the bottom of the outside wall. Using appropriate countersunk head screws, so it doesn’t block the placement of the first plank, fit the plank onto the starter profile and fix with clips on every support. The next plank is then fitted above, using Click Clips on every batten.
The Cedral Click planks are placed with the ends against each other and always on top of an underlying supporting batten. The joint should be protected with a joint sealing strip with sufficient stiffness (we suggest a black polyethylene PE 0.5mm thick jointing stick for joints not exposed to light or a UV-resistant material if they are).
Please note that the distance from the edge of the clip to the edge of the plank should not exceed 60mm. For the final plank at the top of the facade, there are two options. If the facade finishes with a whole plank, simply fix with clips. Alternatively, if the facade requires a trimmed plank, fix with Marley Eternit coloured mushroom head screws, which must be inserted perpendicular to the panel surface using an electric drill and high quality bit.
