When you choose NK Windows, you’re making a conscious decision for a greener tomorrow. Our commitment to warmer, quieter, healthier homes mean our window profiles are designed under stringent environmental regulations. Our uPVC windows are also miles above the new H1 building code for windows and doors, no matter where you live in New Zealand.
By opting for our uPVC windows, you’re taking a stand against deforestation, habitat disruption, and excessive energy usage.
Far too many New Zealand homes suffer from cold and damp conditions, impacting the health and well-being of kiwi families. Launched in 2010, Homestar is an independent rating system that rates the health, efficiency, and sustainability of New Zealand homes on a scale of 1-10. It evaluates various factors such as energy, water, waste, ventilation, health, and comfort.
Christchurch architectural designer Bob Burnett chose to partner with NK Windows when designing his super efficient 10 Homestar Built rated house. All external windows and doors were supplied by us and are standard doubled-glazed with argon and Low-E. Approximately 75% of all solutions we provide use exactly the same glazing options.
The Homestar rating system is essentially a measure of the quality, health and comfort of a dwelling and its energy use, plus other environmental attributes. Bob says, “We can easily do much better to make our homes healthier and more energy efficient and it is a myth that it is too expensive. Unfortunately many new home builders target the building code and perceive it equates to quality, when of course it is simply a minimum.” A house built only to code will achieve 3 or 4 stars out of 10.
NK's uPVC window and door systems are essential for enhancing the energy efficiency and overall performance of high-performance homes. Homeowners can experience substantial reductions in energy consumption and enjoy enhanced comfort and functionality.
A passive house is a high-performance building that sets the gold standard for energy efficient living, designed to be optimised for health and wellbeing, while consuming very little energy. NK are proud to offer a range of products suitable for certified passive houses.
We believe in making healthier and more energy-efficient homes a reality for everyone. That's why we are proud sponsors and members of the Superhome Movement, a not-for-profit organisation dedicated to transforming the New Zealand building industry.
Engineered with precision, our products provide exceptional insulation, minimising heat transfer and reducing the need for constant heating or cooling. The inherent thermal properties of uPVC contribute to a well-regulated indoor climate, resulting in significant energy savings and a more sustainable, comfortable living environment.
