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 rolled mild steel
core which is then sprayed with a proprietary
rust inhibitor before being inserted into its
cover. The covering is a seamless lead extrusion
that incorporates a twin wing weathering
system and glass seatings. The ends of the
cover are then soldered to give a hermetic
seal. Cast brass fixing plates and glass stop
are screwed on to produce the finished glazing
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
The Heritage glazing bar has been
produced by Standard Patent Glazing
for over 100 years. Our extruded lead
glazing bar covers are still manufactured
to this day in our factory using
the original powerful machinery which
has been maintained to a magnificent
level over the decades.
The amount of time taken to produce
each glazing bar is substantially
higher when compared to our modern
aluminium glazing systems and due
to the average heritage glazing bar
weighing more than twice as much as
our typical aluminium Skyline Box
glazing bar, the cost for this system
should not be compared with other patent
glazing bars which are unable to offer
the unique and original characteristics
of our Heritage glazing bar. Typically, our Heritage glazing bars costs are similar to our polyester powder coated Skyline Box SPG7 section glazing bar.
