Following a recommendation from a previous client International Glass Consultants were approached by VR Group who required a detailed glass analysis to be conducted within 48 hours and for a limited budget. Furthermore, a glazing construction and fixing instructions for a large bespoke glass balustrade within a complex residential build.
The initial design from the client was a timber staircase with a glass balustrade along the length of the staircase, this glass would only be held in place at the very base of the glass by 4 bolts through each glass panel with no additional support. VR Group’s current glazing suppliers had no way of understanding how this could be done without severe deflections on the glass panels and compromising on structural integrity and safety.
THE SOLUTION & OUTCOME
Utilising the wealth of technical industry experience, existing relationships and software analysis systems, IGC were able to provide a formal design solution and recommendations for the glass construction and fixings to enable minimal deflection whilst maintaining the desired aesthetic appeal of a fully glazed balustrade along the length of the staircase. Using the Mepla system we ran two models, the first with 12mm toughened glass (this had initially been specified by the client) which showed a deflection of around 46mm under the given line load, the second 10mm tough / 1.52mm SGP / 10mm tough only showed a deflection of 13mm or so which in most situations is considered acceptable.
