Timber in historic buildings: a forensic survey is assessing and finding solutionsto timber defects and failings

Historically the forms and dimensions of solid timbers available are limited by the sizes and forms of trees from which they are processed. In addition, natural strength-reducing features present limited their use. Many years after insertion in to the building fabric, some timbers suffer from degradation.

This session looks at the likely causes of this degradation and the possible remedies that may be employed to deal with areas of degradation in timbers. It also considers how to best protect existing timbers that currently have not degraded, as well as how we can better care for the future of buildings whilst meeting the current standards. Consequences of historical bad practice will also be shown and discussed.

The session will culminate in discussing current research which impacts of the protection of historic buildings and how this knowledge could be applied to present and future projects that delegates may be involved in.

Part 1

  • A bit of history and science: properties and usage
  • Timber decay: what and why
  • Assessing and investigating decay in buildings: from timber framed to joinery and fixings
  • Repairing and treating timber decay and other defects: appropriate methods of repair and maintenance
  • Caring for the future of building and meeting current standards.

Part 2

  • Impact of current standards, where to get further advice, quoting Trada and other sources
  • Current interesting research programmes showing how the subject is evolving and how architects can use the information for their conservation project.

Speaker: Tim Belden, TRADA
Tim is currently the Trada University Engagement Programme Manager, with a Masters Degree in Timber Building Conservation. He delivers timber related lectures to post and under graduates at universities throughout the UK. Tim has worked on many listed buildings of all grades, carrying out timber conservation work, mainly in traditional English hardwoods. He has given advice on heritage issues, for planning submissions for carrying out listed building work and emergency works.
