Aluminium Doors NZ: Types, Uses and How to Choose

For most New Zealand homes the best all round door is a powder coated aluminium door. It resists coastal salt, it will not warp or rot the way timber can, the frames are slim enough to carry large glass, and the finish lasts for years with almost no upkeep. The harder question is which type of aluminium door suits your opening, your budget and the way you want the space to work. This guide compares the main options so you can shortlist the right one before you ask for a quote.

Aluminium door types at a glance

Each door type solves a different problem. Use this table to narrow the field, then read the section that matches your shortlist.

Door type	Best for	Key strength	Watch for
Entrance (hinged)	Front and back of house	Security and kerb appeal	Needs swing clearance
Sliding and stacker	Patios, decks, indoor to outdoor flow	Maximum glass, no swing space	Track maintenance
Security door and screen	Ventilation with locked airflow	Airflow plus a physical barrier	Mesh grade matters near the coast
Double and French	Wide openings, classic look	Full width access	Two leaves to seal and align

• Hinged entrance doors lead on security, sliders lead on glass and flow.
• Security screens add ventilation without leaving an opening unguarded.
• Double and French doors open the widest but ask more of the install.

Aluminium entrance doors

An aluminium entrance door is the workhorse of the front of the house. The frame is rigid, the lock points are solid, and a thermally broken profile helps cut the heat loss you get with older single skin doors. Because aluminium is strong for its weight, you can run taller and wider leaves than timber allows without the door dropping on its hinges over time.

For street facing doors, look at the locking hardware first and the finish second. A multi point lock and a quality cylinder do more for security than any single feature, and a powder coated finish in a darker tone hides marks and copes well with sun and salt. If privacy matters, a solid or honeycomb core leaf keeps the look clean while still taking a glazed side panel for light.

• Prioritise the lock and hinge hardware, not just the look.
• Thermally broken frames reduce condensation and heat loss.
• Darker powder coat tones hide wear on a high traffic door.

Sliding and stacker doors

Sliding doors are the go to for connecting a living room to a deck or patio. They carry large panes of glass, they do not need swing clearance, and a stacker version lets you open most of the opening at once for summer entertaining. The trade off is that the panels are heavy, so the track and rollers do real work and benefit from an occasional clean and a check of the drainage holes.

The two things that separate a good sliding door from a frustrating one are the roller quality and the seals. Smooth rollers keep a heavy panel gliding for years, and good brush seals keep out the wind driven rain that NZ decks see in a southerly. If your opening faces prevailing weather, ask about the weather rating before you commit to a size.

• Best where swing space is tight and glass area is the goal.
• Roller quality and seals decide long term smoothness.
• Clean the track and drainage holes to keep panels gliding.

Security doors and screens

A security door lets you lock the house while leaving the main door open for airflow. For NZ conditions the mesh grade is the detail that matters. Near the coast a marine grade or stainless mesh resists the salt that pits cheaper screens, and a perforated aluminium sheet door gives a more solid look while still moving air. Pair the screen with a deadlock rather than a basic latch so the barrier is more than visual.

• Choose mesh grade for your site: coastal homes need corrosion resistance.
• A deadlock turns a screen into a genuine barrier.
• Perforated aluminium suits buyers who want privacy with airflow.

Double and French doors

When you want to open a wide span in one clean line, double doors or French doors are the classic answer. Two leaves meet in the middle, so you get the full opening when both are open and a traditional look when they are shut. The detail to get right is the meeting stile and the seals where the two leaves close, because that join is where draughts and water try to sneak in. A well made aluminium set with proper weather seals handles this without the swelling and sticking that timber French doors are prone to.

• Full width access with a traditional, symmetrical look.
• The centre seal between the two leaves is the make or break detail.
• Aluminium avoids the seasonal swelling that timber French doors face.

How to choose the right aluminium door

Work through these factors in order. Most of the regret buyers describe comes from skipping the first two and choosing on looks alone.

1. Opening and clearance. Measure the rough opening and check whether you have room for a door to swing. No swing space points you to a slider.
2. Exposure. A coastal or weather facing opening needs a higher finish grade and better seals than a sheltered internal courtyard door.
3. Security level. Street facing and ground floor openings warrant multi point locking and a security screen. Internal or upstairs doors can be simpler.
4. Glass versus privacy. Decide how much light you want against how much you want to be seen, then pick a solid, honeycomb or glazed leaf to match.
5. Finish. Powder coat colour is partly taste, but darker tones hide wear and lighter tones show less heat gain. Confirm the colour is rated for exterior use.

• Measure and check clearance before you fall for a style.
• Match the finish grade to how exposed the opening is.
• Set the security level by how reachable the door is from the street.

What aluminium doors cost in NZ

Pricing depends on size, glass, hardware and finish far more than on the door type label, so treat any single number with caution. As a rough guide, a standard hinged aluminium entrance door sits at the lower end, large glazed sliders and stackers cost more as the glass area grows, and security screens are an add on rather than a replacement. Hardware upgrades such as multi point locks, and bespoke sizes or colours, move the price up. The honest answer is that a measured quote on your exact opening will beat any online ballpark, because a 200mm difference in width or a switch to thermally broken glass changes the figure.

• Size, glass and hardware drive cost more than the door type.
• Bespoke colours and sizes carry a premium over stock options.
• A measured quote is the only reliable price for your opening.

Frequently asked questions

Are aluminium doors better than timber for NZ homes?

For exposed and coastal sites, aluminium usually wins on upkeep because it will not rot, warp or swell, and a powder coat finish lasts for years. Timber still appeals where a particular heritage look is wanted, but it asks for regular maintenance to stay weather tight.

Do aluminium doors rust?

Aluminium does not rust the way steel does. It can corrode in harsh marine air over a long time, which is why a quality powder coat finish and marine grade hardware are worth specifying for coastal homes.

Which aluminium door is best for indoor to outdoor flow?

Sliding and stacker doors are the common choice because they carry large glass and need no swing clearance. A stacker opens most of the span at once, which suits decks and patios used for entertaining.

Can I get a custom size or colour?

Yes. Aluminium doors are made to a wide range of sizes and powder coat colours. Share your opening measurements and the look you want, and we can quote the exact configuration. To understand how the profiles are built, see our guide to aluminium door extrusions.
