Our Skyline Box type glazing bar range has been developed to give specifiers an alternative to traditional internal and external stalked glazing bars. The low profile external aluminium capping offers a smart appearance to the external facade of the patent glazing system and the visual appearance is similar to curtain walling.

Our Skyline Box range of extruded aluminium glazing bars offer an economical roof glazing solution when compared with curtain walling roofing systems whilst maintaining a very similar appearance. 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.
This system is able to accommodate double and triple glazed applications where compliance with Building Regulations Document L are a requirement but is also popular for single glazed applications such as feature canopies and unheated spaces.
Available in four sizes depending on the design span with box section depths of 50mm, 75mm, 100mm and 150mm. This glazing system is capable of spanning up to 7 metres unsupported with double glazed infills weighing 30kg/m².

* 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.
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.
