Avon Framed Glass Balustrade

Ideal for modern architectural homes, the Avon offers any combination of rail type and numerous potential finishes to suit your unique style.  More rectangular top rails give the Avon a minimalist aesthetic often seen in mono-pitch rooves and metallic finishes.  The Avon’s sleek design provides unobstructed views for occupants while allowing onlookers to appreciate the unique architectural style and design of the build.

Scope of Use

The Avon Framed Glass style by UNEX can be used for both external and internal applications, including decks, balconies, stairways and landings, mezzanine floors, pedestrian gates, and pool fences.

Unex Systems’ balustrade brands – namely Aluma, Eclipse Vogue and Arena – are designed to and comply with 'A', 'B', 'E' and 'C3' loadings of AS/NZS 1170.1:2002 for residential applications, office and work areas, as well as areas for moving people without obstacles.

There is a wide range of fixing options available to fix to the top and sides of both timber and concrete substrates. The Unex Systems DKG2 gutter bracket system is designed for membrane decks with gutters and waterproofing considerations. Site-specific specifications may also be provided upon request for those non-standard situations.

The standard powders used by Unex Systems (the Interpon powder coat range) can be used right down to sea level, provided the care and maintenance instructions are adhered to.

Limitations on Use

The Unex Systems brands designed for residential situations, office and work areas, as well as for areas with moving people – namely Aluma, Eclipse Vogue and Arena — cannot be used for 'C1/C2', 'C5' or 'D' Loadings. In these applications, Unex Systems recommends the use of the 'Extreme Barriers' range which has been specifically developed for these higher loadings in crowd and public situations.  

The standard Unex Systems’ top rails comply with the handrail profile requirements of D1/AS1 for 'Private' and 'Common' stairways (with the exception of the #ARC and #ART top rails), but do not comply for 'Accessible Stairways or Ramps'.
Where a top rail of a balustrade on a stairway does not comply with D1/AS1, Unex Systems recommends an auxiliary complying handrail is mounted to the side of the balustrade posts.

For certain buildings such as architectural sky rises (over 3 stories high), light commercial or high pollution areas, a higher grade powder coat powder must be specified.

Statement of Building Code Compliance

Unex Systems has designed its range of balustrade styles in the Aluma, Eclipse Vogue and Arena brands to comply with the B1, B2, E2, F2 and F4 requirements of the NZ Building Code and are suitable for occupancy types 'A', 'B', 'E' and 'C3' in accordance with AS/NZS 1170.

In-Service History

Unex Systems has specialised in designing and manufacturing architectural balustrade systems throughout New Zealand since 1981.  

These framed glass styles have been incorporated in Unex’s range since the early 1990s. There have been a number of enhancements made since this time — in particular during 2008, when the building code changed to incorporate AS/NZS1170 which meant that the required balustrades loads effectively doubled. Unex Systems then redesigned a number of their balustrade extrusions to ensure these loads were adequately met.
