For normal residential use, beams should be placed with a maximum spacing of 400 millimetres. For commercial or public use, a distance of 300 millimetres is recommended. Keep in mind that for two connecting boards, the ends of these two boards must be supported by the same beam. When beams are placed at a 45-degree angle, the distance between them should not exceed 300 millimetres for residential use and 240 millimetres for commercial or public use. For more information on installation, see the installation instructions.
For the boards, by the way, we recommend a 3-6 mm gap between the sides of the boards and a 2 mm gap between the ends of the boards. A 10 mm gap should be left between the boards and every fixed surface to facilitate drainage.
When using our Shadow Line product, it may be necessary to use our Millboard Multi-Spacers during the installation process to achieve a straight and consistent 6 mm gap between the boards.
