Nationwide Windows’ bi-folds are Secured by Design

Nationwide Windows, the UK window and door manufacturer with a 27 year heritage is delighted to announce that its bi-fold doors now meet the requirements of Secured by Design (SBD) – the official UK Police flagship initiative to support the designing out of crime – following extensive testing by the British Board of Agrément (BBA).

Products submitted for Secured by Design status must pass a series of rigorous standards and tests nominated by the police service in order to demonstrate their effectiveness in preventing or reducing crime. The bi-fold doors were certified to BS PAS 23-1: 1999 General performance requirements for door assemblies – Part 1: Single and Double leaf, external door assemblies to dwellings; as well as PAS 24:2012: Enhanced Security Performance Requirements for Doors and Windows in the UK – External doorsets and windows intended to offer a level of security suitable for domestic use and other buildings exposed to comparable risk (BBA Certificate of Conformity Granted).

Nationwide added the Eurocell Aspect bi-fold doors to their already extensive product range of designer windows, vertical sliders, composite doors and conservatories in 2011, after which their popularity soared. The doors are perfect for new build or commercial properties due to the scope of design they provide, such as the architecturally designed concertina action, which provides seamless operation, or the huge choice of colours and woodgrain finishes available. Bi-folds are loved as they allow the creation of extra space, by fusing the indoor and outdoor areas, providing additional light to a room, and Nationwide’s bi-folds can create a glass wall up to 6m wide. The SBD accreditation also means that the doors can be used by housebuilders who require their whole building envelope to meet the standard, where previously they may have, through necessity, had to opt for an alternative entrance.

John Whalley, Managing Director of Nationwide Windows comments:

“We took the decision in 2011 to incorporate bi-fold doors into our offering as we predicted they would be popular in the new build sector, so it is great to see such strong growth in this part of our business. We’ve worked with a large number of housebuilders and commercial developers over the years, and the close relationships we’ve built with them tells us that the interest in bi-folds is showing no sign of waning for a long time yet.

“Given the popularity of bi-folding doors in the UK market, it is somewhat surprising that more of these products are not Secured by Design accredited, but we are extremely pleased that we can now place ours amongst those which are. It’s great to be able to add the additional benefit of this accreditation to our already popular product and pass the security advantages on to our customers and our customers’ customers.”
