Cladding for timber frame buildings
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 and outlines the broad requirements of building regulations to assist in the correct specification and installation of external cladding on timber frame structures.
- Design requirements:
- Cavity barriers
- Differential movement
- Wall ties
- Cavity trays
- Cavity insulation
- Self-supporting cladding
- Brick and block (Variations when using BS 5268)
- Render on self-supporting blockwork
- Non self-supporting cladding
- Battens to support cladding on timber frame
- Junctions with self-supporting cladding
- Render not on self-supporting blockwork
- Tile or slate cladding
- Metal sheet cladding
- Brick slips
- Timber cladding
- Other types
All timber frame walls are designed to 'breathe'. The term 'breathe' refers to the ability of a wall to allow water vapour to diffuse through the structure. This is an important consideration to the long term durability of the timber structure.

This Wood Information Sheet (WIS) outlines the materials normally specified for conventional timber frame buildings. Some variations will occur according to the structural design and detailing requirements of specific projects. Many of the components are also used in innovative forms of construction such as engineered stud and twin stud walls,...
Sole plates are a vital element in a timber framed building. Their installation has a direct effect on the building's service life, line, level and plumb, and contributes to the speed of construction.
This Wood Information Sheet provides advice on getting the installation of sole plates right first...
