Security is increasingly important - not least to insurers. All our members' windows have locking system security that complies with British Standards (BS 6375 Part 3: 2009 Annexe A) with lockable handles and safety restrictors available. Through testing and certification, members can provide reassurance, where necessary, that windows and doors are tested to PAS24 in compliance with Approved Document Q. Many members also have the prestigious Secured by Design accreditation. Windows and doors are available with safety glass. See our Advice Note.
