Professional software for window, facade and glass


Calculating heat flows, isotherms and thermal bridges according to EN ISO 10077-2:2017

Imported CAD files can be analysed automatically and failures in the drawing are removed by the sofware. Therefore complex constructions and systems can be calculated within a short time. Due to the integrated FEM calculating engine, results are determined very precisely

GlasGlobal is the software to calculate the structural analysis for glass regarding to German standard DIN 18008 part 1 – 5.

Exact results can be achieved in less time due to our high-performance calculating engine and the Finite-Element-Method. The loads regarding to European standard EN 1991-1 are preset in GlasGlobal. This makes the software easy to handle and allows an intuitive entry of values.

    Compatible with WinSLT for calculating solar radiation, g- and U-values


Calculating values according to EN 410, EN ISO 673, EN ISO 13363-2 and ISO 15099 / ASHRAE

WinSLT is the software for calculating values for solar radiation and temperatures of glazings combined with sun or heat protection. The construction of a glazing can be defined in short time for calculating all values according to:
EN ISO 673 -> Ug –value; EN 410 -> g –value, reflection, absorption, transmittance; EN ISO 13363-2 -> gtotal –value; ISO 15099 / ASHRAE -> Ug –value, SHGC-value, reflection, absorption, transmittance
Our software is validated by ift Rosenheim and generates the declaration of performance and the CE certificate of the glazing.
