Breather membranes for timber frame walls
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.
A breather membrane restricts the passage of liquid water, whilst allowing water vapour to pass through.
This Wood Information Sheet (WIS) covers a number of topics surrounding breather membranes including the requirements of a breather membrane, the considerations which must be made to mitigate risk of condensation, and the measures which must be taken to mitigate heat loss caused by convection currents.

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,...
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...
Professionals undertaking surveys of timber frame buildings should have an understanding of the overall design and typical detailing employed in this form of construction.
The approach to surveying a timber framed house is no different from that used for other methods of construction. There are many similarities with brick...
