The decay risk of structural timber, wood-based materials, and natural fiber insulation materials can now be assessed much more realistically than before using the newly developed prediction model based on hygrothermal simulations.
This model considers the three key influencing factors: moisture and temperature at the critical location within the material, as well as the duration of exposure to these conditions and its effect on the decay process.

To reduce the CO2 footprint of buildings, renewable raw materials such as wood and natural fiber products are increasingly being used as building materials. Due to their biological origin, however, these materials may be susceptible to decay fungi under certain moisture and temperature conditions, particularly when exposure lasts long enough. For the design of durable assemblies, it is therefore essential to identify boundary conditions under which decay risk can be reliably avoided.

We have fundamentally revised our guideline for assessing interstitial condensation runoff risk in building components.
The new evaluation criteria are based on research findings from the NaVe-Project (in German) and refine resp. replace the previous criteria.
What’s new?
The updated guideline is now available for download. [download]
The English summary from the NaVe project on this topic is provided here.
The new version WUFI® Pro 7 is now available for testing in a new look and with new features. We are working hard on the release, which will be available soon. Meanwhile we are offering the opportunity to test our release candidate in advance and try out the new features.
Here’s how to install the release candidate:
1. Download the archive here <Testperiod finished> and extract it.
2. Run the installation.
3. Start WUFI® Pro 7
A license window will appear – select “Trial version” and enter your name and email address – then you can get started.
Note for UK and Australia: To set your country-specific translation go to Project – Settings and select your countries English from the list.

As part of the »In2EuroBuild« research project, a harmonised European guideline for the assessment of internal insulation systems was developed.
Further project results include:
• A classification of capillary-active internal insulation systems
• New moisture limits for long-lasting wood fibre insulation materials based on durability tests
• A cost-effective measurement system for monitoring internal insulation systems
• New hygrothermal reference years climate data for Belgium based on a scheme developed at IBP
