 Interstitial Moisture

Interstitial Moisture

The interstitial moisture (condensation within the building structure) stream is looking at moisture management in roof spaces - both residential and commercial.

The Building Code currently puts many of the performance requirements of roofs on the properties of underlay - there is no recognition that ventilation can play an important part as well.

This part of the WAVE programme will try to understand the complex airflow patterns that can occur in roof spaces and how these can be controlled in such a way that they manage moisture effectively.
