Application

To be used to the external facade of a patent glazing system, and can accommodate the following:

  • Roof glazing.
  • Railway stations.
  • Double glazed applications (where compliance with Building Regulations Document L is not a requirement).
  • Single glazing applications (such as feature canopies and unheated spaces).

Description

Two edge supported patent glazing system with extruded aluminium glazing bars in an inverted 'T' design.

Features and benefits:

  • The external stalk provides strength.
  • Can accommodate single and double glazing, as well as solid and multiwall polycarbonate sheets up to 30 mm thicknesses.
  • Available with both screw-on and snap-on cappings.
  • Can be combined with opening vents to offer a complete glazing solution.
  • Available in a range of glazing bars to achieve light spans as well as unsupported spans up to 5560 mm.
  • Manufactured in accordance with BS 5516: 2004 Code of Practice for the design and installation of vertical and sloping patent glazing.

Product Options

Glazing bar:

Consult manufacturer before specifying a particular glazing bar.

- TC1:

  • Single glazing: 1340–3160 mm.
  • Canopy glazing: 1450–2690 mm.

- TC2:

  • Single glazing: 1770–4170 mm.
  • Canopy glazing: 1920–3560 mm.

- TW1:

  • Single glazing: 1340–3160 mm.
  • Canopy glazing: 1450–2690 mm.

- TW2:

  • Single glazing: 1770–4170 mm.
  • Canopy glazing: 1920–3560 mm.

- TW3:

  • Single glazing: 2610–5560 mm.
  • Canopy glazing: 2830–4590 mm.

Please note that the lower span values are calculated using the most extreme environmental loadings, whereas the higher span values are based on the least extreme. The manufacturer requests a site postal code to enable them to calculate the correct glazing bar type for every project. The glazing bar spans above are based on using 6 mm thick glass for the, single glazed and canopy types. 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.

Glazing infill:

A variety is available, e.g. clear laminated, heat soaked toughened, etc. Consult manufacturer's literature for information.

  • Double glazed: 28 mm thickness (maximum).
  • Polycarbonate sheets: 30 mm thickness (maximum).
  • Single glazed: Any thickness.
