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 primary consideration. This system has been installed on thousands of projects nationwide, demonstrating its widespread acceptance and reliability. It is available with a choice of capping systems to suit a variety of aesthetic and functional needs, offering versatility alongside its robust performance.
A truly great glazing system, the Traditional patent glazing system combines economy with a proven track record of success. In recent years alone, we have installed over 40,000m² of this system on many major railway stations throughout the UK. This extensive application highlights its durability and effectiveness in high-traffic environments.
The system’s enduring popularity is a testament to its quality and reliability, making it an ideal choice for numerous architectural projects. Whether for large-scale infrastructure or smaller installations, our Traditional patent glazing system delivers outstanding performance and value.
Our Traditional patent glazing bars are designed to receive single glazing of any thickness and are also suitable for accommodating solid and multiwall polycarbonate sheets up to 30mm thick. It is possible to incorporate double glazed units into this range of glazing bar when compliance with Building Regulations Document L is not a requiremnt.
The glazing bar is an inverted ‘T’ design and its strength is provided by the external stalk (or web). The outer surface can be weathered by a choice of extruded aluminium screw-on and snap-on cappings or extruded aluminium screw-on wings.
This system is an upgraded design to our BL Traditional range which has been installed on thousands of projects nationwide. It is available in a range of three glazing bars to achieve light spans as well as large unsupported spans up to 5560mm.

Performance Data for Traditional patent glazing bars
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 us first allowing us to carry out the necessary calculations for your project.
