With SommerGlobal, Sommer Informatik brings together powerful software solutions for the professional calculation and design of glass, windows, and facades. The software suite combines proven desktop applications with 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 the thermal simulation of windows, facades, and thermal bridges in 2D and 3D. It combines automated CAD import with precise FEM simulation in accordance with current European and international standards, including EN ISO 10077-2, ISO 10211, EN 6946, EN 673, and ISO 15099. WINISO® quickly calculates heat flows, isotherms, and Uf and ψ values and reliably assesses the risk of mould and condensation. It is ideal for engineers, planners, and testing institutes that require standards-compliant component verification and visually appealing reports.
WINSLT® is the leading expert software for determining the optical, solar, and thermal performance characteristics of glazing in combination with solar shading systems. It enables glass and slat manufacturers to precisely determine Ug, g, and g-total values in accordance with current European and international standards, including EN 410 and EN ISO 52022-3.By importing custom spectral data, simulating venetian blind slats, and automatically generating Declarations of Performance and CE marking documentation, WINSLT® optimizes the entire product declaration process while ensuring compliance with applicable requirements.
WINTHS® is the leading software solution for calculating thermally induced stresses and preventing glass breakage in facade and window glazing. Developed for engineers, designers, and glass manufacturers, WINTHS® simulates the thermal behavior of glass structures under real-world conditions, taking location, climate, and shading into account. The software performs automated stress analyses in accordance with NF DTU 39 P3. It provides a sound basis for determining whether glass panes need to be heat-treated, thereby reducing the risk of costly glass breakage 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 (Rw, C, Ctr). 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 standards-compliant design of glass structures. The specialized software reliably supports engineers, structural engineers, designers, and glazing contractors in the structural design and calculation of glass components in accordance with national and international standards, including DIN 18008, SIA 2057, and ÖNORM.Its integrated, automated wind and snow load calculations, combined with a manufacturer-independent glass database, enable efficient calculation of stresses and deflections. The software generates structured, independently validated, and review-ready structural calculation reports that provide a reliable basis for approvals.
