Deflection limits for walk-on glass
Deflection under load affects comfort, seal performance and drainage on walk-on glass. Learn why deflection limits matter, what influences bend and how span relates to stiffness.

Deflection under load affects comfort, seal performance and drainage on walk-on glass. Learn why deflection limits matter, what influences bend and how span relates to stiffness.
Walk-on glass load calculations combine dead load, imposed foot-traffic loads and support conditions to determine safe span. This reference explains what goes into the calculation — and what to leave to the manufacturer.
Structural rooflights — including walk-on units — form part of the building's load path. Learn how they differ from standard skylights, what the structure must provide and how to specify them correctly.
Frameless and framed walk-on roof lights use the same structural laminated glass — the difference is edge detail, fixing method and appearance. Compare both options for terraces, glass floors and light wells.
Most rooflights cannot be walked on. Only purpose-made structural walk-on units with a rated laminated glass build are safe for foot traffic — standard flat roof lights must never be used as floor panels.
A step-by-step guide to specifying a structural walk-on roof light: measure the opening, choose frame and thermal options, select glass finish, align structure and order correctly.
Walk-on glass must be structurally rated for imposed loads — not just daylight. This reference explains load categories, laminated build-ups, span limits and what to ask your supplier.
A walk-on roof light is a structurally rated laminated glass panel you can walk across — used for roof terraces, glass floors, landings and basement light wells. Learn how they are built, where they are used and what to specify.
