Damp, Timber Decay and Sustainability Conference
In May 2021, we hosted a virtual conference on moisture in timber. For conservation professionals, the association of damp with timber decay needs no introduction. This is the familiar consequence of poor maintenance and ill-considered alterations. However, the need to reduce heat loss and carbon emissions is posing new challenges for the management of moisture in older buildings. A roof structure, for example, will become colder if heat transfer from the rooms below is reduced, leading to greater risk of condensation, mould growth and timber decay. Ventilation may not always be beneficial.
In this virtual conference, which was held on two consecutive Tuesdays, leading conservation specialists reviewed recent research and explored best practice. The first session focussed on building environments, including Historic England’s latest research. The second considered options for treating and repairing decayed timber.
You can listen to recordings of the conference presentations by clicking on the links below. These presentations will be of interest to building conservation professionals including conservation officers, architects and surveyors.
