Our Heritage Lead Covered Steel Patent Glazing bars are a unique product and encapsulate the very essence of the Patent Glazing tradition. The glazing bar design originates from Victorian enterprise and ingenuity.
The glazing bar consists of a galvanised rolled mild steel core which is inserted into a seamless lead extrusion covering that incorporates a twin wing weathering system and glass seatings. The ends of the lead covers are then soldered to give a hermetic seal. Cast brass fixing plates and glass stop are screwed on to produce the finished glazing bar.
This system is offered today for the replacement, refurbishment and upgrading of grade 1 & 2 listed buildings, buildings of historic value or other prestigious projects. Please note that apart from the Heritage range, no other products are available on the market that can compare to the original lead covered steel patent glazing bar.
The Heritage Lead Covered glazing bar range meets all the requirements of British Standard BS5516: 2004 Code of Practice for the design and installation of vertical and sloping patent glazing.
The Heritage glazing bar has been produced by Standard Patent Glazing for over 100 years. Our lead glazing bar covers are still extruded to this day in our factory using the original powerful machinery which has been maintained to a magnificent level over the decades.
The average heritage glazing bar typically weighs more than twice as much as an aluminium Skyline Box glazing bar and typically, our Heritage glazing bars costs are similar to our polyester powder coated Skyline Box SPG7 section glazing bar system.
Opposite are pages from our 1928 technical catalogue which shows a selection of our projects after a quarter of a century experience in patent glazing. Today we have been in existance for over 110 years and we still strive to offer you the original 'Heritage' glazing bar unaltered for over a century.
