SL-3

Facade Boards for Exterior Building Decoration

Description

Suitable for facades, wall cladding, decorative elements, as well as terraces, sheds, and fences.

The material is dried to a moisture content of 16-20%, which helps reduce the risk of cracking and deformation. The boards are planed and calibrated, ensuring a smooth surface and precise dimensions. They are suitable for further processing, such as painting, staining, oiling, varnishing, or wood charring.
