We’re not just meeting standards; we’re surpassing them. Our standard double-glazed units not only comply with NZ Building Code requirements but go beyond, boasting an impressive thermal resistance rating of R 0.40/U 2.51.
You could also choose windows that include both argon and high-performance Low E. This creates an outstanding thermal resistance rating of R0.77/U1.3, outperforming any thermally broken aluminium joinery in the market.
For those seeking maximum efficiency, our triple-glazed panels boast an extraordinary R (window) Value of R 1.20/U 0.83, ensuring unparalleled thermal insulation and comfort.
The above image was taken using a thermal imaging camera to illustrate the thermal resistance of our standard double-glazed units. The first image shows the window mostly red, indicating heat loss. You can move the slider to the right to see the window with double glazing, the green and blue colours indicating far less heat loss.
A favoured choice among New Zealand homeowners, our high-performance Planibel AS Double Glazing stands out as one of our standard glazing options. Incorporating both argon and advanced Low E (Low Emissivity) technology, it ensures optimal thermal efficiency and comfort within your living spaces. In fact, a significant 75% of our windows are equipped with this top-tier glazing solution, reflecting its popularity and effectiveness among our clients.
Argon, the invisible hero between the panes of double or triple-glazed windows, is a game-changer in creating a thermal barrier. By replacing air with harmless argon, we maintain a comfortable temperature inside your home.
Argon not only acts as an insulator but also ensures even temperature distribution across the window. Bid farewell to chilly spots and welcome a more comfortable living space, reducing the likelihood of condensation and keeping your view crystal clear.
Low E, or low emissivity, is a sophisticated technology that revolutionises the thermal performance of your windows. Our Low E coating acts as a thermal barrier, reflecting heat back into your home while inviting natural light to flood in. It also reduces the transmission of UV light which can bleach furniture.
Our Low E coating, a microscopically thin, transparent layer, acts like a guardian. In winter, it reflects heat back inside, minimising radiant heat loss. Come summertime, it reverses the game, keeping your home cooler and more comfortable.
The U-value for a window measures the heat loss through thermal transfer.
It considers the heat transfer from the warm side to the cold side of the window. The amount of heat transferred depends on factors such as the type of glass, the gas used, and the spacer bar between the glass panes.
The U-value, rated on a scale from 0.01 W/m2K (ultra-low) to 4.8 W/m2K (high for single glazing), indicates how much heat is retained. The lower the U-value, the warmer your home stays.
Typical U-values are:
At NK Windows, achieving low U-values involves a combination of technologies. We utilize Low-E glass and Solar Control Glass to minimize heat loss. Additionally, our windows feature argon gas instead of air between the glass panes and incorporate warm edge spacer bars for enhanced thermal efficiency. The slim-profile frame, composed of a five-chamber profile frame and a six-chamber profile sash, further reduces heat conductivity.
Our passion for creating homes filled with warmth and comfort extends to every detail, including the colour of your windows. We keep it real, offering a variety of choices without overwhelming you with unnecessary options.
We welcome you to come and visit our showroom and see our wide collection of laminate samples, offering a real sense of the textures and finishes that will enhance your living spaces.
The uPVC profile undergoes precision cutting and welding, with steel insertion and the fitting, testing, and glazing of opening and locking hardware all taking place in our Christchurch factory. Additionally, our glass is custom processed and cut in Christchurch by Viridian Glass.
PVC is short for polyvinyl chloride, a type of plastic widely used in construction and various industries since the 1950s. uPVC, or unplasticised PVC, is a specific form of PVC that is highly suitable as a material for window frames.
Its versatility allows it to be used in diverse applications, ranging from window frames and pipes to everyday items like credit cards, water bottles, and blood bags.
Absolutely. The roots of uPVC windows trace back to 1959 when the first commercially available windows graced homes in Germany. Over the years, technology has advanced, and yet, some of those initial uPVC windows are still standing strong. In fact, more than 60% of European homes now boast the reliability of uPVC windows and doors.
Absolutely. Our PVC profiles are crafted with New Zealand’s climate in mind, including those intense UV rays. The same robust formula stands resilient in high UV areas worldwide, from the Middle East to Australia and Latin America.
Definitely. Many of our customer projects involve renovations. We understand the importance of preserving character, and our robust uPVC frames are perfect for bungalows and villas.
No. “uPVC windows” refers only to the frame material. We have access to the same glass options as aluminium and wood window suppliers through our partnership with Viridian Glass based in Christchurch. Most common options include:
