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 hermetically sealed.  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.

Today we have been in existence for over 122 years and we still strive to offer you the original ‘Heritage’ glazing bar unaltered for over a century.

The glazing bar spans shown above are based on using 6mm thick glass for the double glazed, single glazed and canopy types, and the bars being spaced at 600mm centres. We will select the appropriate glazing bar for each contract. Spans are dependent upon the site location and exposure rating, site altitude, distance from the sea, height of glazing from ground level, shape of the roof, pitch of glazing, glazing bar centres, glass weight, wind speeds, snow load, dead load and maintenance loads.

* The above spans for each glazing bar have two values. The lower span values are calculated using the most extreme environmental loadings possible in the UK whereas the higher span values are based on the least extreme. Due to the wide range of these values it is therefore essential that we are supplied with the site postal code to enable us to calculate the correct glazing bar type for every project. There are a large number of variables which are used to determine the maximum span of the glazing bars so please do not attempt to buy any glazing bar materials from us without first allowing us to carry out the necessary calculations for your project.
