How to: Install Cedral Click

Cedral Click from Marley Eternit is the UK’s first and only fibre cement tongue and groove external cladding material. Cedral Click has been specified by housebuilders and contractors looking to create inspirational and visually striking developments, and is now growing in popularity amongst self builders.

In addition to its visual appearance, self-builders and homeowners are specifying Cedral Click due to the performance of the material. Fibre cement is extremely low maintenance, there’s no need for continual repainting and it can stand up to the harshest of weather conditions.

Another key benefit of Cedral Click is its ease of installation. We’ve put together this simple five-step installation guide

1. Fix battens to walls. Position and fix the vertical battens (available in standard fixing 75mm x 38mm and joints/corners in 100mm x 38mm) spaced a maximum of 600mm apart (this is dependent on windload).
2. Attach perforated closures to top and bottom of battens. Perforated closures should be screwed or nailed to both the top and bottom of battens. These are designed to protect against birds, rodents and some insects, whilst still allowing air to flow through the system. Closures are available in depths of 40mm, 50mm, 70mm and 100mm to allow for coverage of external insulation.
3. Fix internal and external corner profiles and horizontal (starter) profiles. Use the horizontal start profile at the base of the external wall and install completely level to ensure the installation of the Cedral Click planks remain perfectly parallel. There is also a window lintel profile to finish off above the window and support the next course.
4. Cut and fix Cedral Click planks. Fixing of planks is achieved with Click Clips (60mm x 40mm), fixed with Marley Eternit stainless steel screws (3.9mm x 30mm) onto timber.
5. At the base of the wall, a minimum 30mm clear cavity must be provided behind the Cedral Click planks with a 10mm free air opening at the base, head and at the window, door or cills. Assembly must start at the bottom of the outside wall and with the purpose designed Cedral Click plank start profile (attached level). Using appropriate countersunk head screws, so it doesn’t block the placement of the first plank, fit this plank onto the start profile and fix with clips on every support. The next plank is then fitted above, using Click Clips on every batten.
6. 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 (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.
