Thomas Magnus, a prominent local resident, had the magnificent Tudor Hall built in 1520 to accommodate a free school. The original building has been adapted and extended over the centuries. It is now known as the Old Magnus Building and houses exhibits for the National Civil War Centre. The Old Magnus building was left vacant in 2004 and quickly fell into disrepair. Newark and Sherwood District Council were successful in obtaining Heritage Lottery Funding to restore the ancient building and transform it into a museum. In so doing the council are insuring that Thomas Magnus’ original vision of creating a space for education continues into the 21st century. Security was high on the agenda when plans were made for the restoration process. Some of the historical artefacts including graffiti dates back to the early 1600s and are irreplaceable. Some parts of The Old Magnus building are Listed and so security measures taken need to be sympathetic to the buildings elegance and historical significance. Window openings are an integral part of a buildings security. Secondary glazing is an ideal solution for Listed buildings which require a high level of security whilst meeting the requirement of being a fully reversible adaptation. 45 windows were treated using a range of Selectaglaze’s bespoke products, including units certified to Loss Prevention standard LPS 1175 level SR3 and PAS24, all accredited to Secured by Design.
