To develop secure interactive and engaging exhibition spaces during a recent large-scale refurbishment of Nottingham Castle, it was important to enhance the security of several large original single glazed windows.

However, the museum’s Grade I status meant enhancements to its security had to be achieved in a careful manner, minimising the impact on the exterior and interior appearance of the castle, originally built in 1068.

Selectaglaze, one of the leading providers of secondary glazing systems across London and the UK, first achieved certification for secondary glazing systems to LPS 1175 in 2004.

The Series 43 secondary glazing system is designed for Listed buildings and was the culmination of testing conducted on several prototypes. This demountable fixed light combines in-built strength and resistance to possible levering, whilst maintaining a slim sleek frame, ensuring its discreetness when installed in an ornate Listed window opening.

Commenting on behalf of Selectaglaze, Zoe Williams said “Selectaglaze has invested a lot of time and money to create the range of security products necessary to meet different specifications and window styles. No other secondary glazing suppliers are able to supply units certified to this level of forced entry protection, which is testament to our achievements”.

The product has been used in many highly sensitive and Listed buildings, including installations in some of the ground floor windows of Nottingham Castle. Use of this LPCB-certified secondary glazing during the recent refurbishment made spaces within the building lighter and more inviting, whilst ensuring that they were secure and that Government Indemnity Scheme requirements were met.

Achieving LPCB certification demonstrates Selectaglaze’s commitment to offering safe products with the highest levels of protection. It aims to preserve heritage by making buildings warmer, quieter and safer and they have been able to provide protection at Nottingham Castle, without infringement on the building’s special architectural features.

When searching for security products and services, specifiers are keen to ensure that a product has undergone rigorous type testing and assessment of the level conducted in support of receiving LPCB’s globally recognised third-party certification. Furthermore, all LPCB-certified products are listed in the Red Book, making it a great resource for users of these products.

Key highlights:

• Certification means Selectaglaze complys with Government Indemnity Scheme requirements for LPS 1175.

• Only secondary glazing supplier able to provide dedicated secondary glazing units certified to this level of forced entry protection.

• Certification has helped to boost customer confidence through alignment with recognised certification.

LPCB certification is particularly attractive to specifiers and regulators, such as The Arts Council, as it provides confidence that products are fit for purpose and have the necessary and associated accreditations.

Selectaglaze has been able to use the knowledge gained during their test programmes to develop a wide range of secondary glazing systems that combine forced entry protection with a host of other functionalities including acoustic and thermal resistance. They will continue to use LPCB certification to demonstrate the effectiveness of their products as they extend their range of secondary glazing systems.
