Vertical timber roof cladding.

Cladding refers to a covering for a structure as well as all the components attached to achieve this. Batten spacing unless specified by your architect or other professional should be fitted at 400 mm centres and meet bs 5534 with a section of 25 mm x 50 mm. The cladding may be fixed to battens attached to a self supporting treated timber frame. Vertical timber cladding profiles include.

It is available in a range of species the tree that the timber originated from and is machined to a range of profiles which determines the way the pieces fit together. Some typical detail for a timber cladding roof can be found here with a timber board fixed to batten over a membrane clad plywood roof.

Standard range vertical cedar claddings select primary no 4 s. They should be fixed at the appropriate gauge onto battens and battens should be strong and stiff enough to withstand the proposed loading while also providing adequate fixing alignment. Premier range vertical cedar claddings no 2 clear and better virtually knot free. Matchboard t g board on board half lap.

Typical section showing fitting of vertical cladding battens time and thought should be taken fitting battens to ensure they produce a level and flat surface for the cladding. In one form a timber clad roof consists of a fully watertight membrane applied to a plywood clad roof with timber battens installed over insulation and castellated timber batten. We recommend jb red factory graded battens.
