Preserving and protecting Nottingham’s history with Selectaglaze secondary glazing

  • 8 Sep 2021

In 2018, the doors to the Grade I Listed Nottingham Castle closed to allow for an ambitious three year, £30m funded project to revive the 17th century Ducal Palace and its grounds; an Ancient Scheduled Monument. Selectaglaze glazing features in this project…

Architects Purcell, based in Nottingham, drew up the specification of works for this Grade I Listed provincial Baroque Style building.

Stonework needed repairing, the original windows refurbishing, reveals made good and their security grilles/trellises removed. To open 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 grant the exhibiting of more prized and valuable collections, as well as meeting the Government Indemnity Scheme obligations.



Selectaglaze collaborated with GF Tomlinson, the appointed main contractor, to ensure the window reveals were tough enough to maintain the integrity of the security secondary glazing.

Upon the completion of all the preparatory work, 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 a risk, so Series 10 and Series 80 horizontal sliders with 6mm toughened glass were installed to improve thermal and acoustic performance. All the windows required carefully crafted splayed timber sub-frames in which to fix the units.

As part of the redevelopment, a stunning but fragile stained-glass window was restored and reinstated in its original location between the Café and Ducal Palace Galleries.

LPS1175 SR3 secondary glazing now features on one side, as it was deemed to be in a vulnerable point of entry and would also provide security and help keep it preserved. Due to its size and curved head, four units were coupled together to deliver a sensitive treatment.

With the project accomplished and new points of interest created to remember some of the legendary figures associated to 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.

‘Bringing the site into the 21st century’

Sara Blair-Manning, Chief Executive of Nottingham Castle Trust, comments: “The transformation that Nottingham Castle has undergone is amazing. We are thrilled with the work that Selectaglaze has carried out, providing protection and preservation whilst ensuring the renovations are sympathetic to the historic architecture – something that is incredibly important to Nottingham Castle Trust.

“Nottingham Castle has a rich history, spanning over 1,000 years, so for Selectaglaze to have been able to maintain that history, whilst bringing the site into the 21st century is a real achievement.”
