Extreme Balustrade — Framed Glass

UNEX Extreme Barriers are specifically engineered to comply with the extremely heavy liveload classes 'C1/C2', 'D' or 'C5' of the New Zealand Building Code legally required for public and crowded areas. The Framed Glass style's thicker glass panels allow larger crowds to continue to watch the game or the view from above.

Key Features
  • Specifically engineered to comply with extremely heavy live load classes C1/C2, C5 and D of AS/NZS 1170.1:2002 and parts of F/G
  • Ideal in commercial applications including sporting facility grandstands, schools, shopping centres and hospitality
  • Commonly used on residential applications as an extra high glazed wind-break screen
  • Designed for standard heights of 1100mm and 1200mm from finished deck level
  • Wide range of finish options
  • Made from 6000 series aluminium alloys and screws together with minimal, if any, welds required

Scope of Use

UNEX's Extreme Barriers Style has two ranges — X1500 Series and X3000 Series

  • The X1500 Series is designed to meet classifications C1/C2 and D of AS/NZS 1170.1, which stipulates a 1.5kN/m load on the top edge — twice the load required on a typical residential application
  • The X3000 Series is designed to meet classifications C5 of AS/NZS 1170.1 which stipulates a 3.0kN/m load on the top edge — four times the load required on a typical residential application.

The Extreme Framed Glass Styles are typically used for, but not limited to:

  • Grandstands
  • Gymnasiums
  • Sports and surf clubs
  • Shopping centres and retail areas
  • Restaurants, cafes, and bars
  • School halls, and public pavilions 

Extreme Barriers are also suited to other situations where large post spacings, a bulkier look or additional height is required.

There is a wide range of fixing options available for both suits to fix to steel, timber and concrete applications. Site-specific specifications may also be provided upon request for those non-standard situations.

Limitations on Use

The UNEX Extreme Barriers Range is designed to meet the loading classifications of AS/NZS1170.1 of the New Zealand Building Code and is therefore not applicable to the requirements of the transport code. So this design is not applicable for applications, such as a vehicle barrier. Typically Extreme Barriers are not suitable for top-mounting to timber.  

For certain buildings, such as some industrial situations, a higher grade powder coat powder must be specified.
