Moisture Monitoring of Built-In Wooden Elements

Article Preview

Abstract:

This paper describes moisture monitoring of wooden elements, which are built-in to structures of building envelopes. This monitoring is helpful in proving long-term functionality of designed details or, conversely, in pointing out of an emerging problem, thus avoiding infestation of these elements by wood decaying fungi or insects, which is usually connected with excessive wood moisture. This can occur in these elements especially when they go through the building envelope from interior to exterior. The described long-term measurement is based on a resistance method and the text explains its principle, mentions factors influencing the accuracy of measurement and shows installation and development of probes, which were designed by author for this kind of measurements.
