Selectaglaze worked with GF Tomlinson, the appointed main contractor, to provide the Grade I Listed Nottingham Castle with a bespoke security secondary glazing solution as part of an ambitious 3 year, £30 million funded project to revitalise the 17th Century Ducal Palace and its grounds; an Ancient Scheduled Monument. To open up the gallery space, making it lighter and more inviting, security secondary glazing which met LPS1175 SR3 was to be installed in some of the ground floor windows. This would allow the exhibiting of more prized and valuable collections, as well as meeting the Government Indemnity Scheme requirements. Once all the preparatory work had been completed, six of the windows on the ground floor had two Series 43 demountable fixed lights, coupled side by side, installed in each with specialist laminate glass. The windows in the mezzanine were not deemed as a risk point, so Series 10 and Series 80 horizontal sliders with 6mm toughened glass were installed to enhance thermal performance and make the space quieter. All the windows required carefully crafted splayed timber sub-frames in which to fix the units. With the project complete and new points of interest created to remember some of the legendary figures associated with the location; visitors will be able to enjoy its varied history and experience the heritage of this iconic site, sitting atop the hill overlooking Nottingham.
