Tradition and innovation: timber as rainscreen cladding

This paper describes the use of timber as a rainscreen cladding on David Chipperfield's River and Rowing Museum at Henley. The extensive use of green oak in this way is the key to a precise and beautifully crafted building and was the result of collaboration between the architects and the Timber Research and Development Association. This use of timber represents a major shift in the work of David Chipperfield from concrete toward a wider palette of materials. Henley is also an important example of a recent trend in the development of timber as an external cladding material. Timber cladding as a rainscreen will be discussed in the context of the Henley project in terms of its performance factors and the design and construction process, and analysed with a view to drawing some conclusions for its future use.
