Why UPVC

Trusted by 100s of happy customers around the country, our new and retrofit windows and doors have been helping keep kiwi homes warmer, drier, quieter and more secure for over a decade.

Designed and made in Dunedin, we understand the New Zealand climate and everything that comes with it. This is why we pride ourselves on providing excellent customer service, quality advice, designer styles and high-quality products to suit homes around New Zealand. From salty, wind-battered coastal cottages to heat-scorched Central Otago homes and humid and damp apartments in the north to suburban family new builds, no matter where you live or your home type, we can create a window and door solution for you.

Enjoy reduced noise, a comfortable atmosphere, increased security and minimal maintenance with our range of designer windows and doors.

Deceuninck offers a wide range of PVC windows to add style and value to your home. A low maintenance, colour-fast, long-lasting window gives your home or building an elegant look that will last for years. No more painting or staining, simply wipe clean and your PVC window will look as good as new. Plus, PVC is the best insulating material for windows. No wonder that Deceuninck products have earned their reputation as part of many low-energy housing designs.

Weather Resistance

Weathering is a common problem amongst most materials used on the exterior of a property. LEGEND UPVC Windows and Doors do not react with water and air and are not susceptible to the natural elements, meaning a longer life span without ageing. All Deceuninck windows and Doors are certified to NZS 4211:2008

Five Chamber Policy

The 70mm thickness of the profile ensures high stiffness of the window or door, and the type of strengthening allows for an increase in glass thickness up to 41 mm. Two multi-function seals made of modern thermo-plastic elastomer (TPE) protect against the loss of heat and are resistant to all weather conditions.

The Deceuninck Zendow window system is designed for New Zealand's harsh UV climate and is protected by a 10-year guarantee for all white profiles and a 7-year guarantee for all coloured profiles against fading; this is much higher than most other window and door system guarantees.

Your new UPVC windows and doors will outperform your old or new aluminium windows or doors hands down and will not require any drip trays.

Environmental Policy

It is not just your home environment we are helping to protect. We want to leave a cleaner environment for our children, and that means using products and techniques that are altogether better for your home and the environment. Our UPVC profile uses environmentally friendly calcium-zinc stabilisers, and our plastics have contained no heavy metals since 2008. Alongside this, Deceuninck incorporates a percentage of recycled materials into its profile, and the TPE seals are 100% recyclable. They have also committed to being carbon neutral by 2050.

Condensation

UPVC frames are guaranteed not to condensate - yes, you read that correctly. Even in the dampest environments, our frames combined with Low-E glass UPVC will eliminate the cold bridging through your window that creates condensation. These are so effective; internal drip trays are not required. Stop wiping excess moisture from your windows and enjoy a warmer, dryer space with our range of door and window solutions.
