Timber clad roof detail.

Drainage of external wall cavity must also be maintained see fig a 8 9. Detail design timber cladding basic principles in principle any timber cladding should be designed as a rainscreen. Timber boarding on timber frame 1 9. Render on timber frame.

Shingles are thin pieces of wood sawn on either side creating a smooth flat surface that is rather uniform in effect. 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. Timber cladding for roofs primarily comes as either shingles or slates each with their own individual aesthetic. Design of timber cladding details.

Details on plan 1. Tile hanging off timber frame 1 8. Vertical timber cladding can come in the form of tongue and groove or board on board along with open joint options too. Non loadbearing wall junctions 1 5.

Horizontal timber cladding is probably the most common and perhaps simpler option. 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. Figure a 8 9typical closed deck timber frame balcony detail at a penthouse level. As such it should be highly durable and tear resistant in accordance with type 1 membranes in bs4016.

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. Detailing of breather membrane and roof covering junction is as typical but care must be taken not to restrict ventilation to timber and or external wall cavity. This timber frame home designed and built by facit homes is clad in timber rain screen coated in a dark stain green oak cladding for instance is likely to move a lot so the battens might need to be positioned closer together to minimise this. The inner wall structure should be fitted with a breather membrane.

This serves to seal the building against damp and weather penetration.
