Glass & glazing calculators
Specifying glass comes down to four questions: is it thick enough for the load, how much does it weigh, how much heat does it let through, and what goes on the document you send the client. These tools answer them one at a time and hand their results to each other, with the standard cited and the arithmetic visible.

Wind pressure on a facade
Design pressure from basic wind speed, terrain, height and where the pane sits, to EN 1991-1-4 or ASCE 7. Hands the result straight to the thickness calculator — which is the input it asks you for.
vb 27 m/s · terrain II · zone A → 2.572 kN/m² design Structural · liveThickness & deflection under wind load
Checks bending stress and deflection for a rectangular pane supported on four edges. Monolithic and laminated, annealed through fully tempered, metric and imperial. Also gives you the thinnest standard glass that passes.
1200 × 2200 · 10 mm tempered → σ 9.96 · w 3.82 mm Handling · liveGlass weight
Weight of a pane, a laminated make-up or an insulating unit — total, per unit and per square metre — and what it means for getting it off the van and into the opening.
1200 × 2200 · 6 mm → 39.6 kg · 15.0 kg/m² · two people Thermal · liveU-value of an insulating glass unit
Centre-pane Ug to EN 673 for double and triple units — air, argon, krypton or xenon, with or without low-E. Splits every cavity into its radiation and gas parts, and tells you the best cavity width for that gas.
4-16-4-16-4 argon · two low-E → Ug 0.61 W/(m²·K) Safety critical · liveGlass balustrade
Stress and deflection of a free-standing barrier under a horizontal line load, at both interlayer bounds — plus the broken-ply check that most calculators quietly skip.
1100 mm · 0.74 kN/m · 12+12 → 16.3 mm, 96 % of h/65 Furniture · liveTable tops and shelves
How thick the glass needs to be for a top, a shelf or a screen — checking the spread load and the concentrated one, which is the check that actually decides and the one most guides skip.
800 mm shelf · 10 mm · 50 kg point → 19.6 N/mm² vs 7.1 spread Deliverable · liveSpecification sheet
