Over 30 years experience has gone into the development of Stern Fenster’s automated window manufacturing plant and glass processing facility, where their extensive range of machines enables them to manufacture a wide variety of custom designed windows, doors and conservatories.

Designed and extruded in the UK to BS EN IS09001:2000, their profile, glass and manufacturing process are covered by British Standards Kitemarks 7413, 7412, 6206 and BS EN 1279

Their windows and doors will come with double glazed units as standard and if you are not familiar with them you will be surprised at the amount of warmth they keep in and the levels of noise they keep out. Safety and Security are of paramount importance with any new windows and doors. That's why we insist on the use of safety glass, either toughened or laminated for critical glazing areas as per the British Standards code of practice BS6262 and in accordance with approved document `N' The Building Regulations.

All Super Fortress door locks are approved by the ABI (Association of British Insurers) and benefit from multi point locks with hook bolts, roller cambs and a deadbolt. The deadbolt is secured against sawing by hardened steel pins. The locks are tested to European Standard DIN 18103, DIN 18251, DIN 18357 and are recognised to conform to BS3621 :1980.

All Super Fortress doors use high security hinges for increased safety and strength.

All Super Fortress windows and doors are reinforced with steel to comply with British Standard Kitemark BS7412. Some Super Fortress products can be upgraded to also comply with British Standard Kitemark BS7950/7412 - Improved Security for Domestic Dwellings, please check with your representative for details.
