Natural Building Technologies (NBT) have invested in the most advanced
computerised moisture modeling software, WUFI, meaning that they can
provide customers with a complete analysis of their proposed building
design in terms of the materials used in its construction and how they
will perform when subjected to local weather conditions and humidity
levels.
The analysis will enable architects and developers to specify the correct materials to safeguard their buildings against moisture damage and decay or health problems related to interstitial condensation. It takes the properties of each individual material within a designed envelope system into consideration, as well as each building’s location, orientation and local climate, according to actual measured weather data.
With the new software, NBT are able to demonstrate the prolonged integrity of their high performance insulation systems in any given situation. This is particularly important for timber frame buildings and for internal insulation applications where the risks of trapped moisture are greatest.
NBT staff have been extensively trained in use of the moisture modeling software by its developers at the Fraunhofer Institute for Building Physics (IBP).
