What is Aluminium
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 double and triple glazed aluminium windows so you can enjoy the look and design without the downsides like its poor insulation.

The windows and glazing are ultra-high performance with superb European engineering.
What are thermally broken aluminium windows and doors?
Thermally broken windows and 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 windows and 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.

Why windows matter
We are a leading supplier of European Aluminium
As the leading supplier of European Aluminium, we partner with the best suppliers to bring you the latest technology straight from Europe. Whether you’re after an industrial-sized project or just a couple of windows, you can trust Koffman to deliver top-quality solutions.
“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.
Reduced condensation
Condensation occurs when moist air comes into contact with a cold surface. Because a thermally broken window frame stays at a similar temperature to the interior and isn’t cooled by the outside air, it significantly reduces the likelihood of condensation forming on the window surfaces.
Why choose aluminium?
Our aluminium frames have been designed to reduce the effect of being cold with the inclusion of plastic and foam insulation inside the window frame. We can offer aluminium frames that match the energy efficiency performance of our uPVC options.

Q. Why is aluminium the more expensive option?
Aluminium windows from Europe have superior energy performance compared to locally thermally broken frames. Internal insulation components can give Koffman aluminium windows the same thermal properties as uPVC. We can accommodate triple glazing and offer twin colour options as standard. This is a premium product.
Q. What is better, uPVC or Aluminium?
The two systems are different and comparison needs to be based on the specific needs for each application. Both systems can be equally good regarding thermal performance. uPVC can be less expensive but may have size limitations when compared to aluminium which is a stronger material. Colour choices are also practically unlimited in aluminium.
Q. Do we need triple glazing in NZ?
Triple glazing will keep your house warmer in the winter but equally it will help to keep it cool in the summer. For that reason it is recommended for all regions of New Zealand.
