This grade will include more frequent and larger knot potentially soft dead knot may also have larger face splits wane and sapwood.
Vertical timber roof cladding.
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.
Detail design timber cladding basic principles in principle any timber cladding should be designed as a rainscreen.
Timber cladding is a widely used common exterior finish for buildings.
Vertical cladding existing buildings.
Cladding refers to a covering for a structure as well as all the components attached to achieve this.
Assuming that the cladding will always be subject to some penetration of moisture a separate protective membrane will be necessary behind the cladding largely protected from wind rain and daylight by the cladding itself.
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.
Solid walls shall be protected from water penetration by either a water repellent coating or breather membrane.
We recommend jb red factory graded battens.
Premier range vertical cedar claddings no 2 clear and better virtually knot free.
Fitting a breather membrane between cladding battens.
Standard range vertical cedar claddings select primary no 4 s.
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.
These include a vertical joint timber look board and batten look and express joint composite panel look.
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.
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.
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.
