With SommerGlobal, Sommer Informatik brings together powerful software solutions for the professional design of glass, windows, and facades. The product suite combines proven desktop applications with modern cloud features.
Calculations, projects, documents, and user-defined materials can be securely stored, managed, and accessed from anywhere.
WINISO® is the leading building physics software for thermal calculations of windows, facades, and thermal bridges. It combines automated CAD import with precise FEM simulation in accordance with current European and international standards (e.g., EN ISO 10077-2). The software calculates heat fluxes, isotherms, and Uf and Ψ values in no time at all and reliably analyzes risks of mold and condensation. Ideal for engineers, designers, and testing laboratories that require legally compliant component verifications and visually appealing reports
WINSLT® is the leading specialized software for calculating the photometric, solar, and thermal performance characteristics of glazing systems in combination with solar shading. It enables glass and venetian blind manufacturers to precisely determine Ug, g, and g-total values in accordance with current European and international standards (e.g., EN 410, EN ISO 52022-3). By importing custom spectral data, simulating venetian blind slats, and providing integrated, automated generation of declarations of performance and CE markings, WINSLT® optimizes the entire product declaration process in a legally compliant manner.
WINTHS® is the leading software solution for calculating thermal stresses and preventing glass breakage in facade and window glazing. Designed for engineers, designers, and glass manufacturers, WINTHS simulates the thermal behavior of glass structures under real-world environmental conditions (location, climate, shading). The software automatically performs stress analyses in accordance with the NF DTU 39 P3 standard. It provides a precise basis for deciding whether glass must be thermally tempered, thereby minimizing the risk of costly damage after installation.
WINSPZ® is the leading specialized software and database for managing and analyzing sound test reports in the window, facade, and glass construction industries. Designed for manufacturers, acousticians, and designers, the system enables a quick, targeted search for tested sound insulation values (R_w, C, Ct_r). WINSPZ® significantly simplifies the process of providing documentation in compliance with DIN 4109 and EN ISO 717-1. Instead of laboriously managing documents manually, the software instantly generates legally compliant acoustic certificates for bids, thereby minimizing administrative overhead in daily operations.
GLASGLOBAL® is the leading, modular structural analysis software for the code-compliant design of glass structures. This specialized software reliably supports engineers, structural engineers, designers, and contractors in the computational design of glass components in accordance with national and international standards (such as DIN 18008, SIA 2057, or ÖNORM). Thanks to the integrated, automated load calculation for wind and snow, as well as the manufacturer-independent glass database, stresses and deflections can be efficiently determined. The result is structured, independently validated, and verifiable structural analysis reports that serve as a sound basis for approvals.

Founded in 1996, Sommer Informatik GmbH, based in Rosenheim, specializes in highly sophisticated software solutions for the structural and thermal analysis of windows, facades, and glass.
The software portfolio includes calculations for the structural analysis of horizontal and vertical glazing systems for Germany, Europe, Switzerland, Austria, and the U.S., as well as calculations of lighting, solar, and thermal performance characteristics of glazing systems in combination with sunshades.
In addition, calculations of thermal stresses occurring in glass surfaces can be performed. The product range is rounded out by software for calculating heat fluxes, isotherms, Uf and Ψ values according to EN ISO 10077-2, as well as Ufr, Ueg, and Ucg values according to ISO 15099 / NFRC 100, including 2D and 3D thermal bridge calculations.
Ongoing collaboration with research institutions and industry ensures the high quality standards of the software solutions.
