Calculation Software
for Structural Glazing
For Facade Engineers, Glazing Contractors & Architects
Use VitraLab for structural glazing calculations through separate EN 16612 and draft-based Eurocode 10 routes. Check glass weight, laminated glass, EC10 EET and partial shear coupling, DGU and TGU systems, ULS stress, and SLS deflection under wind, snow, live, maintenance, barrier, and accidental actions.

What VitraLab Calculates
Structural Glazing Calculations in One Place
Enter the glass build-up and project loads, then review combinations, governing results, stress, deflection, and utilization.
Glass Weight & Dimensions
Use pane dimensions and configuration data to support glass weight, dead load, and structural glass design checks.
Applied Loads
Apply wind, snow, live, maintenance, accidental, and barrier loads using separate, visible inputs.
ULS Checks
Review ultimate limit state stress effects and governing load combinations for glass design.
SLS Deflection
Check serviceability deflection limits with reported values, utilization, and pass/fail results.
Design Output
View calculation summaries, utilization, pane results, and detailed ULS/SLS combination effects.
Who It Is For
Built for Professionals Who Work with Glass
VitraLab is intended for facade engineers, glazing contractors, architects, and others who need to review structural glass calculations.
Facade Engineers
Run structural glass checks, review load combinations, and compare ULS/SLS output for facade elements.
Glazing Contractors
Check practical glass build-ups, pane dimensions, and load cases before progressing design coordination.
Architects
Understand glass feasibility, approximate build-ups, and structural limits earlier in the design process.
Design Checks
Structural Glass Checks for Real Load Cases
VitraLab supports the design checks typically needed for glass in facades, roofs, balustrades, partitions, and other glazed elements.
✓
ULS Stress Checks
Ultimate limit state stress effects and governing design combinations.
✓
SLS Deflection Checks
Serviceability checks with stated deflection limits and result summaries.
✓
Horizontal & Vertical Glazing
Separate loading conditions for horizontal and vertical glass.
✓
Monolithic, Laminated, DGU & TGU
Pane-level results for common glass configurations, including EET laminated panes and TGU within the implemented EC10 scope.
✓
Wind, Snow, Live, Maintenance & Barrier Loads
Load inputs aligned with practical facade and glazing design scenarios.
