Heritage Patent Glazing System

For listed or historic buildings, the Heritage patent glazing system merits serious consideration.  

The design of the Heritage patent glazing bar originates from the late Victorian period and remains substantially unaltered to this day and the Heritage system, the original Standard Patent Glazing system is the only patent glazing system still available on the market that features the original lead cover surrounding its hermetically sealed patent glazing bars. 

If your objectives include historic building conservation, or your project involves a listed, prestigious or architecturally important building and you want to help protect its special architectural and historic interest during its replacement, refurbishment or upgrading, then the Heritage system is unmatched.  And because it’s unique, it’s also very suitable for new build projects where aesthetic design values are uppermost in the architect’s mind, being part of an architectural toolkit which can play a very important role in helping to create a unique statement building firmly rooted in the traditional architectural vernacular.

The Heritage patent 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. 

Whilst the system remains substantially unaltered compared to its original incarnation, certain components and our manufacturing techniques and equipment have been improved over time to ensure that the system continues to meet quality expectations and continues to be compliant with relevant legislation and standards. 

Heritage Patent Glazing bars meet all of the requirements of British Standard BS5516: 2004 Code of Practice for the design and installation of vertical and sloping patent glazing.  

The average Heritage Patent Glazing bar typically weighs more than twice as much as an aluminium SkyLine Box Patent Glazing bar, but typically, Heritage Patent Glazing bars costs are similar to the polyester powder coated SPG7 glazing bar section from our SkyLine Box Patent Glazing system.
