|Glazing bar material||
The Skyline patent glazing bar system has low profile external aluminium capping that offers an alternative to traditional external stalked glazing bars with a smart, clean appearance.
The bars and caps are extruded to the company's own dyes from grade 6063 temper T6 aluminium alloy.
Different depths of box section glazing bars are available, depending on the span required, or to provide various internal design effects.
The majority of the glazing bar resides permanently on the inside of the building and consequently maintains a higher temperature, providing a lower thermal transmittance than an external stalked glazing bar where a wider surface area is in contact with external elements.
A thermal break is included for double-glazed installations to further reduce the effects of cold bridging.
The Skyline glazing system is suitable for double-glazed applications where compliance with Building Regulations Document L is a requirement, but is also popular for single-glazed applications such as feature canopies.
When used with double-glazing and thermal breaks this system is capable of providing an overall U Value of approximately 1.8W/m²K.
To maintain a low profile within the roof line the internal part of the glazing bar is removed, called the ‘stalk’ at the top and bottom positions where the bars are secured to the supporting structure. A small tolerance is incorporated to allow for some variation within the finished structure, however, accuracy is required within the structure otherwise any variations will become apparent.
