Aluminium windows

Windows are important for both functionality and aesthetics

Our unique thermal frame is designed by our in-house technical team. Each part is carefully considered to bring you a strong, effective, and superior window. Thermal properties mean that less heat is lost or transferred through the window, making the building more energy efficient.

Our design team utilised feedback from our factory and customers to create a seamless end-to-end solution, all tested to NZ Standards.

Tested up to and beyond NZ Standards - incl. NZS4211

Window types

Fixed windows are a great way to capitalise on scenery as the large panes of glass provide unobscured views. Fixed windows also work well as sidelights, providing additional light beside entrance doors, or to brighten up passageways and stairwells.

Awning windows are top hinged opening windows. They’re a great option for ventilation and are the most common type of opening window in New Zealand homes and offices. Combine a set of awning windows with fixed windows for style and flexibility.

Casement windows are side-opening windows and are equally as good as awning windows for providing ventilation and light. Casement windows are often selected as a design feature throughout a home, or when the windows are tall and the height of the window doesn't allow for an awning-style opening.

With two sliding panels, the stacker window allows you to have around two-thirds of the window size open. Bi-parting stacker windows are great to achieve a larger opening. Any sliding window is ideal for openings which open to a walkway or deck as the window doesn’t obstruct past the frame like a bifold or hinged window.

Sliding windows are great when you want a window that is easy to open and provides a bigger opening or to maximise the airflow or allow people to connect between the inside and outdoor areas. Another benefit of these windows is that as they are sliding, they do not protrude past the frame which makes them safe for walkways.

A bifold window is made up of hinged panels that fold back towards the frame to create a large opening. Bifold windows are ideal for areas such as kitchens, outdoor areas, and cafes.

Why is a thermally insulated window better than double glazed?


Thermally insulated windows are better than double glazing alone as the aluminium profile has a plastic strip that reduces the heat transfer through the frame. Double glazing is a good option, but adding a thermal frame to your selection will improve the insulation and energy efficiency of the house.

Does UNO do replacement windows?


Sorry, our specialty is windows and doors for new build homes, multi-residential developments, and light commercial buildings so we don't work with replacement units.

I'm doing a reno, can UNO supply the windows and doors?


Sorry, windows for renovation projects is not a service we offer. We specialise in windows and doors for new builds including new homes, multi-residential developments, and light commercial buildings.
