Welcome to Apex Windows
Apex Windows is an old company with a new name. We began manufacturing Altherm Window Systems in June 2017 to enable us to provide a complete product offering to homeowners but our experience in the industry dates back much further.
We are a forward thinking and passionate company always looking for the best solution for our customers whether you need one window or solutions for a large scale commercial project or an architectural home.
Our core business is supplying house lots of new and replacement joinery to the greater Central North Island from Tauranga to Hawke's Bay and around Mt Ruapehu.
Our staff are ready to help you make informed choices about your windows and doors and what we can offer your home - call us today to discuss your needs.

About Altherm ThermalHEART technology
Advanced ThermalHEART technology lies at the centre of each profile in Altherm Residential Series and Metro Series ThermalHEART. The result - maximum energy conservation and interior comfort. A thermal insulator has been cleverly included into each window and door to ensure that cold transfer is minimised and interior warmth is retained. This powerful enhancement combined with high performance double glazing makes for the ultimate in sensible year-round living.
Why Choose ThermalHEART?
- Thermal Efficiency – Thermal Performance up to 35% better than standard double-glazed windows.
- Reduce Condensation – ThermalHEART can aid in managing the risk of condensation forming, therefore reducing the risk of mould growth.
- Variety of options – There is a full range of window and door option to choose from.
Choosing a colour for your windows and doors requires careful thought to enhance the overall appearance of your home. Colour selection may be influenced by your home’s cladding and interior colour schemes. The window colour may complement the cladding colour, with tones a few shades up or down, or contrasting joinery colours may be popular, especially darker natural tones and silver.
Powdercoating is the most popular surface finish and offers a huge range of colour options that cater for buildings in all locations. Our popular colour range includes 35 colours that are also available to colour-match your hardware to the joinery.
Note: when you are choosing your aluminium joinery colour, always assess the colour in natural light using an aluminium colour swatch.
The colours shown are an onscreen guide only and no guarantee can be given that they will be an exact colour match for the finished product. View our physical swatches for an exact match.
® Dulux, Duralloy, Duratec and Metropolis are registered trade marks of Dulux Powder and Industrial Coatings. We use Dulux Powder and Industrial Coatings.
Anodised finishing is a highly popular choice for architectural projects, and is a durable and colour fast technology that offers an alternative to powdercoating. Altherm offers matt 'frost' finish as standard.
As for colours and film thicknesses, there are plenty of options: Silver, in 12 and 25 microns. Bronze in light, medium or dark, 12 and 25 microns. Black, 25 microns only. Champagne, in 25 microns only.
For properties in coastal, industrial or other corrosive environments, 25 microns is recommended, and may even be required to qualify for a warranty. (Note: the anodised coating has a 10-year warranty for 12 micron anodising, and 20 years for 25 microns.)
Note: when you are choosing your aluminium joinery colour, always assess the colour in natural light using an aluminium colour swatch. We are able to provide you with the colour swatch samples upon request.
