Software solution for calculating light technical, solar and thermal properties of glazing
Compatible with

WINSLT® is the software solution for calculating light technical, solar and thermal properties of glazing in combination with solar shading.

Any structure can be created in a short time and according to the standards:

ISO 673 -> Ug value
EN 410 -> g -value, reflection, absorption, transmission
ISO 13363-2 ->gtotal - value
ISO 15099 / ASHRAE -> Ug value, SHGC value, reflection, absorption, transmission

can be calculated. The software is certified by ift-Rosenheim also generates a declaration of performance and CE marking of the glazing.

In WINSLT® you can import and use your own spectral data sets for coatings, glasses and sun protection. The climatic boundary conditions are freely selectable.

Furthermore, the structure can consist of any number of glass panes and a lamella module is available as an add-on. After your calculation, the performance data determined for the respective product variants can simply be transferred to the declaration of performance and printed out.


  • Extensive database with various products from international glass and sun protection manufacturers
