Timber cladding is becoming increasingly popular once more as a facing material, replacing brick or rendered finishes with warm and practical facades that are seen as a more sustainable option. It is used for internal or external applications, although you must consider the durability of the timber when selecting material for external use.
Timber cladding is a method that consists in fixing of the ventilated cavity and timber boards to the outside of the building. The system encases the property and bring aesthetic timber look finish.
The face width of tongued and grooved vertical boards should not exceed 125mm.
The most versatile fixing method is board on board. Any overlap should be a minimum of 20mm.
Open joint boards should have an 8-15mm gap at the ‘water face’. Chamfered edges allow the boards to overlap slightly, reducing any exposure of the cavity.
Shiplap or feather edge type boards should have a minimum of 15mm overlap, but allow 2mm gaps between the up-stands for expansion.
Tongued and grooved boards should have a maximum face width of 125mm, with a 2mm clearance above the tongue for expansion.
Installed with the tongue upwards.
