Natural wood is an ancient material that creates a relaxed ambience, and is increasingly being used as a cladding material.
Some designers are extending this design ethos by cladding the roof in addition to the walls.
Creating a seamless timber clad structure and roof is deceptively complex. Not only does a multi layer roof system need to be designed, but a wall cladding structure than conceals gutters and downpipes needs consideration.
Detailing, along with choice of wood, is critical. Timber for roof applications must be dimensionally stable, as a pitched roof will collect more ultra violet rays than in a vertical application.
Selecting durable timbers with a vertical grain orientation is a suggestion, as “quarter sawn” or vertical grain timbers are proven to be more stable in highly exposed applications. Abodo’s Vulcan Cladding is one such timber.
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.
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.
