Product Description


Software for the calculation of heat flows, thermal bridges, isotherms, psi and Uf values according to EN ISO 10077-2:2018. Imported CAD files can be prepared with automatic recognition and correction of CAD errors. Thus complicated components and systems can be analyzed and calculated with short computing time and small data sizes.

  1. Calculation according to the „radiosity model“ (new cavity model according to EN ISO 10077-2:2018) and with equivalent conductivity (EN ISO 10077-2:2012/ 2018)
  2. Detailed transfer of CAD data incl. Radii and bevels
  3. Automatic material assignment based on CAD layers
  4. Gas filling for inter-pane spaces according to DIN EN 673 freely miscible



Expert software for the calculation of the static proof of glazing according to DIN 18008 part 1 to 6. The fast FEM calculation core enables an exact calculation of different glazing. The load assumptions according to DIN EN 1991 - 1 are stored in the program, which enables intuitive and simple operation of the software.

  1. Overhead and vertical glazing, fall protection, point – fixed, walk able and accessible glazing
  2. Wind and snow loads and town heights by postcode or town name
  3. Symmetrical and asymmetrical LSG
  4. Automatic glass thickness optimization



Software solution for the calculation of light technical, solar and thermal characteristics of glazing in combination with sun protection. Any structure can be created in a short time and calculated according to the standards EN ISO 673, EN 410, EN ISO 52022-3 and ISO 15099.

  1. Extensive database with various products of international glass and sun protection manufacturers
  2. Import of own spectral data
  3. Boundary conditions according to EN ISO 52022-3, ASHRAE or freely definable
  4. Calculation of any pane construction
