The fiber cement cladding installation depends on many variables, such as:
Fiber cement claddings and boards have excellent adhesive properties, various types of cement mixtures are well combined with them. This option is useful because claddings are used as a layer between concrete and tiles. As a result, hydro-, sound- and thermal insulation is achieved, the surface of the wall or floor is leveled, there is no need for long and costly wall sanding, ceramic tiles last longer.
In many cases, fiber cement cladding installation requires a special approach. It is recommended to install profiles only at a certain step distance (more detailed information in the table and on the diagrams). So, the distance between the bearing elements made of steel or aluminum is from 400 mm to 600 mm in width, and 400-1200 mm in length. At the same time, it is necessary to strictly observe the dependence of the installation parameters of fiber cement boards regarding the thickness of each board.
Below is the recommended distance between fasteners (screws) in mm, depending on the board thickness and location. It is highly recommended not to exceed these values.
The manufacturer also produces clips of various shapes and sizes. They are helpful in carrying out both complex installation of ventilated facades, and room interior decoration. You can find out more detailed application information at an individual consultation. Below you can see the available range of fastenings.

The gap between the board and the insulation layer when applying a ventilated facade technology should be 20-30 mm.
M-profiles should be additionally fixed with horizontal guides before the board installation.
Leave 3-4 mm gap between the boards. Treat the seams with acrylic or polyurethane paste. The surface can be painted with water-based acrylic paints.
After installing the interior panels, it is recommended to thoroughly vacuum the room.
When installing, make sure that there are no such defects:
This process requires slightly different installation technology. At the same time, the price of installing fiber cement siding should not differ significantly.
The basic rule is lap siding. Fiber cement siding from our supplier is a thin board with a natural wood texture, which looks high-priced, especially in low-rise construction.
Basic installation rules:
The price of fiber cement board installation depends on the contractor, and since fiber cement is a fairly new product for our market, you may find excessively high prices. On the other hand, the low price is really captivating. So, what to do?
Before ordering this service, make sure that the contractor has experience and knowledge of all installation rules! Choose mounting systems from the fiber concrete manufacturing plant. Our consultants are ready to guide you when choosing and installing fiber concrete boards. Contact us!
