Solid boards can be installed horizontally or vertically on prepared insulation, which must be finished with reinforcing mesh and adhesive, and painted black. Larch battens measuring 4 × 7 cm are fixed onto the insulation at 70–80 cm intervals, which provides façade ventilation. They are screwed into the brickwork. For a vertical board layout, additional horizontal battens 2 × 7 cm are installed at a spacing of up to 50 cm, forming a grid. If you want the decorative section (with solid boards) to be flush with the standard façade, the insulation in that area must be reduced by at least 6 cm. In that case, insulation with the same or a similar thermal performance is used. Around windows and doors, a black metal sheet 2 mm thick is installed, fixed to a wooden substructure, onto which the boards are then fixed. The total thickness of this section is approx. 1.5–2 cm. The solid boards are fixed from the front with visible RF shiny screws. Finishing details can be done with solid boards (visible fixing) or other solutions as desired.
