Barrier Design & Glass
3
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
6
Barrier Height
900 –
1100mm
Design trend
> 1100mm
7
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.)

Strength
UDL and concentrated load applied to glass
Line load applied to handrail
10
Deflection limits
Line load, UDL and concentrated load applied to glass
Maximum deflection 25mm
11
Deflection limits
Maximum deflection 25mm or span / 65

Safety - containment
Full height barriers – line load and BS 6262-4
Infill panels and free standing
Line load, BS 6262-4 and containment*.
No break or no large opening at
Highest drop height BS EN 12600 test.
* Free path greater than 1.5 m, class A.

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.
45
Free Standing Barrier - Guidelines
0.36 kN/m – 12mm
0.74 kN/m – 15mm
