High-quality cladding system needing the following parts: fastening battens, nylon fasteners and painted panels
By building with wood from SCA you help to bind carbon dioxide. In 2019, SCA's operations contributed to a climate benefit of 10.5 million tonnes.

Wind-shield boards must first be attached to the frame structures of the outside walls. Vertical mounting battens are attached over the windshield board at the positions of the frame boards, based on the distribution of the frame boards. The background structure (wind-shield board and mounting battens) must be straight before the installation of the panels. The mounting battens must be in line with each other. We recommend that the mounting battens be mounted on the windshield board with self-drilling screws.
In horizontal cladding panel installation begins from the lower edge. First attach the concealed clips horizontally to the lower edge of the mounting battens. Attach these lower clips with screws.
Install the panel inserting the tongue into the groove upwards on top of the clips and press them down firmly. Press the next concealed clips onto the mounting battens and press them firmly onto the panel. Install the next panel. Secure the clips of every fifth layer by drilling with 3x25 countersunk screws or by nailing with 1,7-2,3 x32 nails. If necessary, the clips and panels can be taken off the mounting battens by pulling from the side off the clips. Make panel extensions at the position of the mounting battens.
The ends of the boards must be painted or otherwise surface-treated.
Compared to untreated wood, thermally treated wood has superior ability to resist decay and withstand weather. Exposure to weather does cause its color to fade and grey, and without surface treatment, small microcracks may appear on the wood’s surface. Nevertheless, thermally treated wood does not crack, warp, cup or curl the way untreated wood does, because after the heat processing it no longer changes shape. If no surface treatment is applied to the ends of the wood, however, water may seep out there and cause cracking.
It is not possible to give one set of instructions to cover all installations of thermally treated products. Maintenance requirements depend on many factors: the prevailing climate, fluctuations in humidity, specific location and if any surface treatment has been used. The cladding may be exposed to strong UV radiation which causes surface wear. Impurities carried by the wind may intensify the problem in some locations.
Exterior cladding is not generally exposed to as harsh stress such as a decks because water does not collect on its surface. Even so, we recommend checking the condition of exterior cladding annually.
Impurities such as air-borne pollutants and pollen should be cleaned off the surfaces as quickly as possible before they become fixed in place. It may be enough to wash with water, but a gentle soap solution can also be used on wood to remove more stubborn dirt. Painted surfaces can be cleaned with cleaning products recommended by the paint manufacturer. (Recommended cleaning products can be found here)
If you need to touch up any damage or paint the ends of the cladding panels, paint on clean, firm and paint-dried timber. You should only paint when the weather is suitable for painting. You should not paint if the temperature is below + 5 degrees.
