Does UNEX only provide proprietary balustrade systems?
UNEX has a large range of proprietary and pre-engineered balustrade systems.  However for those larger projects, our design team can happily work with the architect and developers to provide a site-specific balustrade design, to suit the design requirements.  In this case, our standard profiles are mainly utilised which makes for a more cost-effective solution rather than designing and manufacturing a whole new system.

What colours are available?
UNEX Balustrade Systems can be powder coated in almost any NZ powder coat colour (including wood grain) or even anodised.  There are an extensive range of common colours detailed in the colour chart.

How far apart will the posts be spaced?
The posts are generally spaced between 1.0 and 1.4 metre centres, depending on a number of factors. The key factors that determine how far apart the posts are positioned include; how the balustrade is fixed, what substrate the balustrade is fixed to, post type, height, site wind speed, site location and the balustrade style. In order to determine the maximum post spacing more exactly, please refer to the technical manuals or contact UNEX for assistance.

What should I use to clean my balustrade?
Firstly, remove loose deposits with a wet sponge. Do not dry-dust, as the surfaces will be scratched. Remove any moss growth and ensure that all drain holes are unblocked, particularly those at the base of the posts and underside of glazed lower rails. Secondly, clean the surface using a soft brush and a mild detergent in warm fresh water - a bit like your car! Pay particular attention to any areas not washed naturally by the rain. Thirdly, always rinse well after cleaning with fresh water to remove any remaining detergent. Refer here to the full ‘Care and Maintenance’ document for your balustrade.
What is the difference between a Balustrade and a Fence?
A Balustrade is a barrier in any building element intended to prevent a person from falling and to retain, stop or guide a person. A Fence is a barrier for all other situations where there is no fall – e.g. a Pool Fence. Reference to the New Zealand Building code and Acceptable Solutions must be referred to for full details.

What height does a balustrade need to be to comply with the building code?
The minimum balustrade heights are as indicated on Table 1 of the Acceptable Solutions F4/AS1 available here. “Detached dwellings” are typically the interior and exterior of a residential dwelling. “All other buildings” apply to all other building situations. Reference should also be made to the current New Zealand Building Code, in particular Clause F4, for a full guide.

Is a balustrade required if the difference in level is less than 1.0 metre?
In these situations, a balustrade is not required by the New Zealand Building Code, however if a balustrade is installed is must comply with the balustrade loads as indicated in the Guidance on Barrier Design issues by the Ministry of Business, Innovation & Employment (MBIE).

What are the glass requirements for UNEX Balustrade systems?
All glass used in balustrading shall be Grade A Toughened Safety Glass manufactured in accordance with the requirements of the Australia and New Zealand Standard (AS/NZS 2208).  Glass shall be selected and used in accordance with our fabricators manuals and the requirements of New Zealand Standard (NZS 4223).  Refer to NZS 4223 for a full guide. Where a patterned or obscure glass is required, screen printing is preferred to sandblasting as the latter compromises the integrity of the glass.

How do I know my balustrade will comply with the building code requirements for a balustrade?
UNEX can provide a producer statement for our proprietary methods, to certify the balustrade design is fully compliant with the New Zealand Building Code. This certificate is available from your local Authorised Fabricator or Specifier. For custom designs, the technical team at UNEX may also provide a site-specific producer statement. (Please note: engineering consultation fee may apply).

What are the different types of Producer Statements?
There are four different types of Producer Statements, which are briefly summarised below.  PS1 – This is a Producer Statement certifying the balustrade design. It is the most common type and is supplied by UNEXs via our online “EziSpec” Producer Statement Wizard, accessible to both Specifiers and our Authorised Fabricators. PS2 – Design Review Producer Statement - this is a review of the PS1 by another independent company. These are available from UNEX upon request. PS3 – Installation Producer Statement - supplied by our Authorised Fabricators physically installing the balustrade to certify it has been installed according to our specifications. PS4 – Installation Review Producer Statement - a review of both the PS3 supplied and the installed balustrade by another independent company. This type of producer statement is very uncommon.
Where do I get a quote? Who can I buy from?
UNEX designs and manufactures the balustrade systems. UNEX balustrades are only distributed and supplied by through a nationwide network of experienced UNEX Authorised Fabricators who have been trained on how to properly quote and install our balustrade systems.  It is important to UNEX that the balustrades are installed as per the specifications and are fully compliant with the New Zealand Building Code. You can purchase UNEX balustrade systems from an Authorised Fabricator in your area.  Contact the UNEX Customer Services team, who will put you in touch with your local Authorised Fabricators.

What information do I need to provide to get a balustrade quote?
The information that is required to provide a balustrade quote includes but isn’t limited to the following; Style of balustrade Layout of the deck (including the deck edge dimensions) and the number of balustrade metres required Details on the substrate that the balustrade is to be attached to (e.g. top or side fixed to Concrete, Dry Timber, Steel, etc.) Type of building, e.g. residential house, pool fence, commercial, etc. Height of balustrade Windspeed Finish and Colour – powder coated or anodised Location of job Due to the number of factors that influence the price of a balustrade, they need to be quoted on a job-by-job basis.  Please contact UNEX or your local Authorised Fabricator for a more accurate proposal.

Why is there such a big difference in price between a framed and frameless glass styles?
A frameless glass style requires a much thicker glass that a framed style and this is impacts significantly on the cost. For example, a framed glass style typically uses 6-8mm thick glass and a frameless channel system uses 12-15mm thick glass.
