1. www.sommer-informatik.de 1 WinSLT  the software solution for calculating the heat transfer by radiation divided into transmission, refelction and absorption of glass (with and without) shadding and the consequence: Total energy transmission and U-value  according to:EN 410 EN 673 EN 13363-2  printout for declaration of performance  precondition for CE mark

2. www.sommer-informatik.de 2 WinSLT two versions  standard Editor: according to EN 410, EN 673 maximal three glass panel no ventilated space between panes no changeable conditions no plain material no slat no import of spectral data for user defined materials  Expert version: self defining slat any number of glass panels variable conditions plain material and spectral data can be edited

3. www.sommer-informatik.de 3  clear and user-friendly interface  any combination of glazing and space between the panes  consideration of ventilation  any angle  freely definable conditions  the note-window gives clues for a fast and proper solution easy operation

4. www.sommer-informatik.de 4  producer data base for Datenbank namhafter pane, coating, foil, gas, slat  you just need to edit the thickness  gas mixture and component can user defined combined easy operation

5. www.sommer-informatik.de 5  you only need slat width, centre distance, slat tilt, sun height and you get resulting thickness and degree of shading  or take a complete slat systems Individual calculation of slats

6. www.sommer-informatik.de 6  with precise values of your own systems you get a exact calculation  possible for any component import of data

7. www.sommer-informatik.de 7  Software calculates all important data like light transmission, lightreflection outside, overall energy transmittance, heat transfer coefficient  according to EN 410, EN 673 and EN 13363-2  program gives advice if wrong entry made calculation

8. www.sommer-informatik.de 8  layers with temperature  complete documentation of all values  table of spectral data in the wavelength range between 300 and 2500  printout in english as well printout

9. www.sommer-informatik.de 9  precondition for CE mark  description of the glazing  all significant features for CE-certification as per product standard EN1279-5 declaration of performance
