Timber Decay in Buildings: The Conservation Approach to TreatmentThis is the first book to tackle all the issues relating to timber decay. It presents the facts and explores timber decay problems through case studies. These are illustrated with clear self-explanatory photographs for the reader to use as a diagnostic aid. Section 1 discusses timber as a living material, Section 2 deals with decay organisms and their habitat requirements. Section 3 moves on to the building as an environment for timber and discusses the ways in which wood responds to moisture change. Section 4 ends with an approach to timber decay which integrates knowledge on the decay organism, its requirements and natural predators with appropriate and targeted chemical treatments. |
