Up until 2004 the buildings were in constant use, first as a school, until 1910, then as the town's museum until 2004 when it fell into disrepair. Newark and Sherwood District Council was awarded Heritage Lottery Funding to restore and transform the Old Magnus Buildings into a new museum and National Civil War Centre continuing Thomas Magnus' vision for all to have access to education, the new museum will also be a centre for Civil War learning.

Home to many important historical artefacts and some graffiti dating back to early 1600s, security was high on the agenda when plans were first made for the buildings restoration. As the buildings are listed any security measures taken had to be sympathetic to the buildings elegance and historical significance. The Architects Purcell and the Main Contractor Woodhead Heritage turned to Selectaglaze to provide protection to the vulnerable window openings. Secondary glazing is the ideal solution for listed and historic buildings even when high security is required as it offers performance in a fully reversible adaption which is accepted by most heritage bodies.

Selectaglaze treated 45 window openings with 6 different product styles including curved units in four different colours. Varying levels of security were provided, using products certified to Loss Prevention standard LPS 1175 level SR3 and those meeting the security standards of PAS24, all accredited to Secured by Design.

Secondary glazing can achieve a U-value of around 1.9, noise reduction of 42-45dB, and even in its most basic form a barrier to potential intruders. Selectaglaze boasts a wide range of products that can provide these various benefits.

Selectaglaze is the leading specialist in the design, manufacture and installation of secondary glazing. Established in 1966, and Royal Warrant Holders since 2004 it has extensive experience and knowledge of working with all building types including listed and new build.
