Health. Warmth. Comfort.

For most of us building a new house, those three things are going to top our wishlist. And these days you can add another: sustainability.

Klima® delivers the most comfortable of homes while helping you keep power bills under control. Based on a premium series from Europe by Kömmerling but designed and manufactured here to suit Kiwi conditions, Klima® is the ultimate energy-efficient window and door solution. And it’s not just a matter of maintaining a snug home in winter – Klima® keeps things comfortable year-round. 

The key is the use of uPVC, a natural insulator with low conductivity. Popular in Europe, uPVC joinery reduces the transfer of both hot and cold temperatures and is the smart and sustainable alternative to timber and aluminium. What’s more, highly durable uPVC is capable of withstanding New Zealand’s harsh sunlight without discolouring or degrading, and offers excellent noise reduction.     

Inspired by Europe, designed for New Zealand, made for your home, Klima® is the sustainable choice.

The Ultimate in Thermal Efficiency

We Kiwis have a tradition of grinning and bearing unhealthy houses. Even now, a third of our homes are too cold in winter, and more than a third are too warm in summer.

35-50% of heat in a home is lost through windows and doors. Much of the problem lies with our choice of windows and doors and decades of sub-standard housing, which has resulted from poor regulation of the minimum New Zealand Building Code standards and a lack of maintenance*. So, if we want to build future-proof homes that stay comfortable, healthy, and energy efficient whatever the season, we must start by making smarter decisions about windows and doors.

Klima® capitalises on the natural insulating properties of uPVC, a material well-known to Europeans, who take it for granted that they can, if they wish, enjoy their homes dressed 365 days a year in t-shirt and shorts. 

When used with high-performance glazing, Klima® windows and doors achieve a maximum six-star energy rating under the WEERS (Window Energy Efficiency Rating System) system. In terms of the Homestar scheme, Klima® can help a building achieve a ‘top of the class’ six Homestar rating. The system is also in harmony with Passive House, the energy-efficient design and construction methodology whose five key principles include the use of well-insulated, high-performance windows and doors.

Why is Klima® so good? It comes down to the innate low conductivity of uPVC and the clever design of the joinery. The result is a house that’s significantly cheaper to heat in winter, cool in summer, and simply healthier year-round.

Optimised for New Zealand conditions

How do you test the durability of window joinery? In the case of the Klima®, try four years of intense testing in the harsh Australian desert. By using a device that followed the sun to maximise daily exposure*, those four blazing Australian years produced the equivalent of 22 years of sun exposure in this country. Yet thanks to the special qualities of uPVC, Klima® showed no sign of cracking or blistering.   

That shows you just how much work we’ve put into optimising the Klima® for local conditions. Essentially, we’ve taken an already highly successful product and further engineered it to withstand New Zealand’s high UV levels and unique conditions. Klima® is designed and built in New Zealand specifically for our place. 

There’s nothing mysterious here for Kiwi builders either. Klima® is installed in exactly the same way as aluminium joinery. It’s business as usual on the building site, but a whole new world of performance for your home.

H1 Energy Efficiency building code changes

Final changes to the minimum insulation requirements for housing set out in clause H1 Energy Efficiency of the New Zealand Building Code came into effect in November 2023. We have moved from 3 climate zones to 6 to allow a more nuanced approach to climatic factors and window suitability. Zones 1 - 4 are required to achieve a minimum 0.46 R Value, with cooler zones 5 - 6 requiring a minimum 0.50 R Value. 

It’s all part of New Zealand moving to Carbon net zero by 2050 with more thermally and energy-efficient windows and doors playing their part. With Klima® uPVC windows and doors, combined with high-performance glazing, you'll be ahead of these increases.
