WINTHS®
WINTHS® is the software solution for simple and user-friendly calculation of the climatic conditions acting on glass panes, taking into account geographical location and historical weather data in accordance with NF DTU 39 P3.
WINTHS® makes it possible to determine the occurring thermal stresses on glass surfaces in advance with regard to extreme weather data, thus drastically minimizing the risk of glass breakage.
In the calculation, WINTHS® takes into account a wide range of factors that influence the thermal loads on glass surfaces. The pane structure is fundamental: glass quality, edge quality, gaps, gas fillings, type and thickness of the frame and its thermal inertia.
These values are set in relation to the prevailing climatic conditions at the installation site. The basis for this can be existing climate data (average and extreme values) for this region, as well as freely selectable values.
The results are displayed in the form of graphs. In addition, all relevant calculation results are displayed to the user in a detailed report, including a summary of whether the respective glass structure satisfies the locally prevailing temperature fluctuations.

- Location
Definition of the location from which the outdoor temperatures and irradiance levels are determined for the specified days during the calculation. WINTHS® provides over 3600 climate data sets worldwide for this purpose. - Partial shading
A sun visor, a canopy, a loggia or the building structure can cast a temporary or permanent shadow on the glazing. This effect is taken into account when calculating the thermal stress. - Installation angle
Installation angle in relation to the horizontal for vertical, horizontal and inclined glazing. - Orientation
Alignment of the glazing in relation to the north direction. Automatic calculation for up to 8 cardinal points.
- Bearing
In accordance with NF DTU 39 P3, WINTHS® distinguishes between all-sided support and constructions with one or more free edges of the glazing. This has an effect on the permissible stress through the coefficient ka (NF DTU 39 P3 Tab.9). - Glass edge
The risk of crack propagation depending on the processing of the glass edge (sawn, cut, machined) is included in the calculation of the permissible stress through the coefficient kv in accordance with NF DTU 39 P3 Tab. 11. - Frame type
The frame is characterized by its thermal inertia (generally low inertia), material and frame U-value Uf. This information is used to determine the temperature profile of the glass in the frame (zone 1).
- Result printout
A clear result printout displays all values at a glance - Graphical display
The graphical display of the glass structure with the layer temperatures simplifies the evaluation of the data - Result
The result of the verification and the maximum utilisation are displayed clearly and simply - Display of temperature distribution
Temperature distribution of the 3 zones under consideration can be visualized for each orientation and each time period in curve form or false color display.
