Cladding for timber frame buildings

TRADA image

The main functions of cladding on a timber frame building are to provide weather resistance and create the external appearance required by the client.

Materials for cladding can be subdivided into two main categories: those which are self supporting (built from their own foundation and tied back to the timber frame structure) and those which are fully supported by the timber structure.

This Wood Information Sheet (WIS) describes the main types of cladding for use on timber frame buildings with insulation between studs and an external cavity wall to provide ventilation for the timber frame and drainage of any water that may penetrate the cladding. It outlines the broad requirements of building regulations to assist in the correct specification and installation of external cladding on timber frame structures.
