National Army Museum
B40 Frameless Glass
The National Army Museum in Chelsea opened again to the public in 2017 after it underwent a major refurbishment over three years at a cost of £23.75m.
The refurbishment was designed to open up and extend the museum exhibition space to allow for a seamless appearance throughout the building. The increased space made way for new exhibitions and learning facilities.
BDP Architects specified a balustrade solution that did not impede views into the open atrium area.
The outside of the balustrade was to have a completely seamless appearance with no protruding handrail brackets visible. The balustrade also needed to be cantilevered off the edge of the concrete slab to create a neat interface with the finished floor levels and outside cladding details.
BA Systems were contracted by Gilbert-Ashe to provide the B40 Frameless Glass balustrade product to the central voids and stairs.
To achieve a seamless base fixing without compromising on the necessary 1.5kN/m loading, the BA Systems’ design team designed a cantilevered steel fixing bracket with gusset supports. This allowed the glass to be mounted 100mm from the edge of the concrete slab (Fig. 1).
To achieve the necessary visual standard, a 21.5mm clear toughened and laminated low iron glass was specified. The handrail detail was fixed to the glass with a countersunk bracket to ensure that no handrail brackets would protrude through the glass .
