Glazing Standards
BS 6180 :
2001
Barriers in
and about
buildings is
referenced
in Technical
Guidance K
Technical Guidance Document K, also references EN 1991-1-1

Barrier Height
900 –
1100mm
Design trend
> 1100mm

Barrier Strength
Horizontal forces:
Domestic - internal 0.5 kN/m (0.5 kN/m2 UDL, 0.25 kN conc.)
Offices 0.75 kN/m (1.0 kN/m2 UDL, 0.5 kN conc.)
Some Retail 1.0 kN/m (1.5 kN/m2 UDL, 1.5 kN conc.)
Restaurants & Cafes 1.5 kN/m (1.5 kN/m2 UDL, 1.5 kN conc.)
Sports halls & Grandstands 3.0 kN/m (1.5 kN/m2 UDL, 2.0 kN conc.)

Fixing barriers
Bolted free standing
BS 6180
42
Fixing barriers
Aluminium shoe fixed at 200mm centres.
Wedges at 200mm centres.
43
Handrails
BS 6180 - Handrail requirement –always a handrail unless laminated toughened glass construction is used.
