Composite Doors

Alexander Windows we are proud to offer the UK’s most comprehensive range of Rockdoor Composite Doors.  We offer all styles of Rockdoor Doors in a choice of coloured outer skins. Choose from White, Onyx Black, Sapphire Blue, Ruby Red, Emerald Green and Anthracite Grey Rockdoors, as well as our original woodgrain options of Rosewood and Golden Oak. Wood grains and colours are available on one side only or both sides if required. Wood grain doors are mounted into a wood grain outer frame, while coloured Rockdoors are mounted into a white outer frame, which brings out the rich colours of the doors.

Rockdoor Composite Doors are manufactured around a galvanised steel subframe, which runs all the way around the outer part of the Composite Door and is encased by a rigid, high- impact 3mm thick uPVC exterior skin that is protected by exclusive Heatshield Technology. The Rockdoor door is then filled with expanding foam under pressure, which reaches every part of the door and sets hard, providing unsurpassable structural integrity and impressive insulation.  The locking mechanism on the Rockdoor Composite Doors is comprisedof two steel hook bolts, a latch and a mortice lock. It is possible to have additional hookbolts, Yales, split spindles, t-bars and steel mesh: these are available as optional extras. On installation, Rockdoors are fitted into a steel reinforced outer frame which again provides more strength making your house even safer and providing you with increased peace of mind.

All of our Rockdoor Composite Doors are PAS 23 and PAS 24 approved. It is also possible for your door to be Secured By Design, which is an accreditation regulated by the Association of Chief Police Officers. Please feel free to call us for more information on 0800 954 2500.
