What VitraLab Calculates
Everything You Need In One Structural Glass Calculator
VitraLab brings key glass design inputs, loads, combinations, and verification checks into one focused workflow.
Glass Weight & Dimensions
Use pane dimensions and configuration data to support glass weight estimates and structural glass design checks.
Applied Loads
Include wind, snow, live, maintenance, accidental, and barrier loads in a controlled calculation workflow.
ULS Checks
Review ultimate limit state stress effects and governing load combinations for glass design.
SLS Deflection
Check serviceability deflection limits using clear output values, utilization, and pass/fail verification.
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 designed around real project workflows for facade, glazing, and architectural teams.
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.
