Structural Glass

Structural stability
The system can be designed to meet even the most demanding horizontal U.D. line loading requirements set out in Table 4 of BS 6399-1. The horizontal load capability depends on the thickness of the glass, for example:

Horizontal line load requirement
[kN/m] Minimum glass pane thickness
[mm]
0.74 15
1.50 19
3.00 25
Durability
The Laidlaw structural glass balustrade system is suitable for both internal and external use.

Touch characteristics
Although stainless steel has a greater durability than timber when used externally, the timber alternative would feel less cold to touch in very cold winter conditions. According to clause 5.10.1 of BS 8300, wood handrails are preferred in these circumstances.

Visual clarity
A key issue for people with impaired vision is the appreciation of the borders of the space through which they need to walk. On the access routes of public buildings, therefore, the use of tinted glass or manifestation on balustrades will give visually impaired people a greater feeling of security.

As with traditional glass infill panels, the structural toughened glass can be tinted grey, bronze, green or blue, or receive manifestation in the form of acid etching or an applied emblem or logo.

Health and safety
In buildings likely to be used by children, safety on staircases and landings is paramount. Approved Document K includes guidance designed to minimise the risk that small children will become trapped, for example between the bars of the balustrade, or will have a serious accident as a result of climbing the balustrade. The fact that the Laidlaw structural glass system has no gaps and is extremely difficult to climb is a major benefit.

Anti-ligature
The structural glass balustrade is particularly suitable for buildings where it is necessary to avoid all likely ligature points, e.g. for prisons and mental health institutions, in which the Laidlaw range of Anti-ligature architectural ironmongery is appropriate.
