Balustrade BEST PRACTICE

NCC 2022 V2

Any balustrade system to withstand expected loads
Must be designed and structurally certified
Dependent on the location and use
Glazed systems rely on a common rail or specialized laminated glass to prevent fall if a panel fails
Confirm acceptance of system & selection with owner & certifier
Where a balustrade meets a window or other uneven element, mullion or transom, openings may become larger than allowed
Ø 125mm opening compliance may be affected
Risk for climbing
Fixed furniture, taps etc. must not be installed near a balustrade
Wire balustrades
Avoid as this requires regular maintenance
Have high certification failure rate & facilitate climbing
