What are Wellington Aluminium Doors?
Wellington Aluminium doors are doors constructed primarily from aluminium, a lightweight and durable metal known for their strength, resistance to corrosion, and low maintenance.
Aluminium is highly conductive, as a result, aluminium doors and windows are prone to losing heat and condensation. At Koffman, we provide top grade thermally broken doors so you can enjoy the look and design without the downsides.

Thermally Broken Aluminium Doors
Designed for the construction of high thermal performance aluminium joinery fulfilling the strictest requirements.
We offer a range of aluminium door options, please contact us to discuss what would best suit your project!
- High thermal performance due to the multi-cavity thermal break and bi-component central gasket
- Large-dimension structures possible
- Wide range of available hardware
- Profile bending available
- Customisation of colour – Both on the inside and outside
- Can use the same foil as uPVC to match uPVC windows
- Stops heat escaping
Door Opening Types
French
- The door opens by swinging both panels outward from the centre
Tilt and Slide
- The door tilts inward at the top for ventilation. The entire sash opens for the door to slide horizontally open.
Lift and Slide
- The door lifts off its track, once lifted the door can be effortlessly slid along its track.
- Minimising the wear and tear on weatherproofing when comparing conventional designs.
Entrance Doors
- The door opens by swinging inward or outward on hinges located on one side of the door frame.
Bifold
- The doors can be set to open inwards or outwards.
Triple Slide
- The door can allow for two sliding panels and one fixed, or all three panels can slide.
We offer a range of door opening types, please get in contact to learn more about what we can do at Koffman.
Install your windows right
Triple glazing is the standard

What are thermally broken aluminium doors?
Thermally broken doors are insulated in both the frame and glass. They feature double or triple glazing with layers of argon gas between panes, separated by non-conductive spacers. This design interrupts the transfer of heat through conduction, making them highly efficient.
Why are thermally broken doors important?
Standard double glazing keeps the heat in and cold out but it does not prevent heat transfer through the window frame. Aluminium, being highly conductive, is not an effective insulator. By incorporating a thermal break within the frame, using material that poorly conducts heat, the transfer of heat through the window is significantly reduced.

Why is not all thermally broken aluminium the same?
The effectiveness of thermally broken windows and doors depends on the size of the thermal break. Larger thermal breaks can interrupt more heat transfer, providing better insulation and energy efficiency.
Warmer in winter
Cooler in summer
Reduced energy consumption
Reduced condensation
Installation Matters in Wellington
“Many products which theoretically meet new H1 requirements will be creating thermal bridging and condensation both inside the house and inside the walls.“
Windows should be installed recessed into your wall, this means the line of thermal barrier down the middle of the glass and frame are connected. If the windows are hung out over the cladding, you can expect to experience heat loss, condensation and a cold and draft feeling close to the window.
How is my home more secure with Koffman?
The glass in our windows is fitted from inside the house, which means unlike other frames, the glass isn’t susceptible to burglars pulling the rubber seal and removing the glass from the outside and gaining entry without making noise.
Multipoint locking system: The turn of a handle locks the sash surrounding the window, unlike single latch windows in NZ. Our windows have min RC2 rating and RC3 – these are possible with specialised glass option.
RC2
All-round fitted system with octagonal locking bolts, steel keeps on the frame, lockable window handle and anti-drilling protection which ensures resistance to attempted break-ins.
RC3
Equipped with an even higher number of octagonal locking bolts at small distanced between locking points. RC3 can also withstand intensive burglary attempts with tools.

Q. What are thermally broken aluminium doors?
Thermally broken aluminium doors feature an insulating barrier within the frame, typically a plastic profile, which separates the inner and outer layers of aluminium. This reduces heat transfer
Q. What colour options are available?
There is practically unlimited colour options
