The BS 7412 Kitemark means that regular testing is carried out by British Standards for  'Plastic Windows made from PVC-U Extruded Profiles' - the testing ensures the windows meet acceptable 'basic' weather ratings and security. For information about enhanced security windows, see BS EN 7950. Spire Windows holds the full suite of kitemarks for double glazed windows and was one of the first UK double glazing manufacturers to receive the Secured by Design accreditation on enhanced security windows and doors.

What BS 7412 uPVC Double Glazing means to you

Not all PVC windows and doors are made equally - because not all PVC profiles are made equally.

Installing double glazed windows and doors made of a BS 7412 profile in your property ensures you have the highest quality uPVC (PVC-u) profiles available in the UK. It means your windows and doors came from a manufacturer that is audited by BSI and works to a strict quality control system.

A company like Spire Windows in Louth, Lincolnshire is inspected regularly to ensure that all quality management systems, including quality control, are being adhered to and the same quality is applied to each and every double glazed window and door they manufacture. Ultimately, It means you are buying a quality product.
