Our Skyline Box range of glazing bars offer an economical roof glazing solution when compared with curtain walling roofing systems. The glazing bar's strength is provided by an internal box section. The glazing bar is weathered by a screw on pressure cap (PC1) with a choice of plain (PC2) or ornate (PC3) cosmetic outer snap-on cappings to conceal all fixing screws.



When used with high performance double glazing units with warm edge spacer bars and argon gas filling this system can achieve an overall U Value of 1.4W/ m²K to comply with Building Regulation Document L.


Our Skyline range of glazing bars offer an economical roof glazing solution incorporating slim sightlines. The glazing bar's strength is provided by an internal stalk (or fin) which is cut away at the top and bottom main fixing positions.
An internal snap-on ornate capping system (PC4) is also available if desired to fully conceal the internal stalk giving the appearance of a feature timber rafter.



When used with high performance double glazing units with warm edge spacer bars and argon gas filling this system can achieve an overall U Value of 1.4W/ m²K to comply with Building Regulation Document L.


Timber rafters (supplied by the builder or joinery sub-contractor) will create an appealing visual effect inside any home and are totally protected from the effects of weathering by our externally clad Rafterline Patent Glazing system.
Due to the pleasing aesthetics of aluminium and timber materials our Rafterline system is the most popular specifiers choice for domestic projects.



When used with double glazing and thermal breaks this system is easily capable of providing an overall U Value of 1.6W/ m²K to comply with Building Regulation Document L.


Our Traditional patent glazing system remains our customers most popular choice for use on unheated spaces such as Railway Stations, glazed canopies and covered ways where thermal properties are not a consideration.
This system has been installed on thousands of projects nationwide and is available with a choice of capping systems to suit your needs.
A truly great glazing system combined with economy and a proven track record. 30,000m² of this glazing system has been installed by us on many major railway stations throughout the UK in recent times.



This system is capable of accommodating solid or multi-wall polycarbonate sheets or double glazed units up to 28mm thick if used on unheated spaces or where compliance with Building Regulations Document L are not a consideration.


Our 'Heritage' Patent Glazing Bar range is truly unique amongst roof glazing systems; there are no alternative products available on the market which can match an original lead covered steel patent glazing bar which originates from the Victorian era. This range has been manufactured by us unaltered for over a century and is the perfect product for listed buildings and for use in the refurbishment of significant and historic buildings. This system is also still very popular for new build projects and should not to be overlooked on today's modern buildings where a unique character look is desired.

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.

* 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 us first allowing us to carry out the necessary calculations for your project.

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.
