Explore our wide range of window configuration options

Our uPVC windows combine style, functionality, and energy efficiency to enhance any space. With a range of sizes, designs, and finishes, we have the perfect solution for your project.

Fixed Windows

Fixed windows are great for letting in light or to frame a view when an opening isn’t required. Modern homes often choose large fixed windows to create a feeling of spaciousness or as a statement design feature. Full height windows are a great way to let light into a passage space.

Configurations

Awning (Opening) Windows

Awning windows are the most popular type of window, with a simple top hung sash (opening) for ventilation and aesthetics.

Configurations

Casement Windows

Casement windows are a traditional style, the simple difference is the opening is side-hung rather than top hung to create a more traditional or colonial style.

Configurations

Sliding Windows

Our sliding windows are a great option for opening a kitchen or seating area out onto a deck or view. With sliding windows the opening will be half of the window size.

Configurations

Stacker Windows

Our stacker windows are another great option for opening a kitchen or seating area out onto a deck or view. With stacker windows the opening will be two thirds of the window size.

Configurations

Invisifold Windows

Bi-folds are the perfect solution to maximise your opening with door panels folding and sliding to one or both ends creating a large panoramic opening. Bifold windows are often used in a kitchen area to connect the preparation area to the outdoor area – a perfect option for those that enjoy entertaining friends and family.

Exellence in Design

Windows The Way They Should Be

The Stärke Ambiance™ inline window system is designed for recessed installation providing the clean lines of a modern aesthetic. All of the insulating materials line up – your timber framing, in-wall insulation and energy efficient windows avoiding any gaps of thermally inefficient materials for the outside air to circulate through.

  1. SECURITY – Multi-point locking and internal beading provide much increased resistance to unwanted intrusion.
  2. DURABILITY – UV resistant uPVC especially formulated for New Zealand conditions, tested and proven to last.
  3. GLAZING CAPACITY – Standard 24mm glass capacity, or right up to 41mm for triple glazing.
  4. WATER-TIGHTNESS – Welded corner connections prevent leakage from corners common in old aluminium systems.
  5. THERMAL PERFORMANCE – More thermal insulation than thermally broken frames can achieve. Window R value of R0.74.
  6. AIR-TIGHTNESS – Double co-extruded rubber gaskets at front and rear of sash prevent air leakage, retaining warmth in the home.
  7. STRONG – The 32mm insulated steel bar adds additional strength.
  8. CONTINUOUS THERMAL BARRIER – Stärke Ambiance™ Inline Window System ensures the thermal barrier within the window and glazing remains aligned with the insulation inside the wall to minimise heat loss.

Frequently Asked Questions

Find answers to common questions about uPVC Windows, their features, and maintenance requirements.

  • Where are Illuminate’s uPVC windows made?

    Our uPVC windows are manufactured in Auckland by Starke, who are the leaders in uPVC manufacturing for windows and doors in New Zealand. They use extruded uPVC imported from an expert uPVC producer in Germany. All windows and doors are then made-to-order at Starke’s state-of-the-art manufacturing facility. Illuminate is the official Starke reseller in the Waikato.

  • How much do uPVC windows cost compared to aluminium joinery?

    Our uPVC joinery is similar in price to thermally-broken aluminium, but has 48% better insulation efficiency. This increased efficiency means that you don’t have to spend as much on other costs that would otherwise be needed for H1 insulation compliance (which is the minimum standard for new homes). This can save thousands when building a new home. Architects or builders can test this out by putting an R-Value of 0.74 into their thermal rating calculations for all windows and external doors on the house plans, and see how it impacts the overall thermal envelope of the house.

  • Do uPVC windows warp or discolour over time?

    There is a common misconception that uPVC may warp or discolour over time. However, the truth is that uPVC is highly durable and is resistant to rot, corrosion, and fading, ensuring long-lasting performance and minimal maintenance. Many years ago (back in the 1970s and 1980s) there were some issues with uPVC yellowing over time, however, modern uPVC is extremely durable and does not warp or discolour. uPVC has been used for windows and door in UK and Germany since 1970’s and is the most common joinery used due to its exceptional insulation and durability.

  • What about doors? Do you have sliding doors, bifold doors, stacker doors or glass doors?

    Yes, we offer a full range of uPVC sliding doors, bifold doors, stack doors and glass doors. View our doors page to see the range. We also have a wide range of entrance doors, including timber and aluminium doors, that fit perfectly into our uPVC joinery. View these on the entrance doors page.

  • What are R-values?

    An R-Value is the “thermal resistance rating”. It is the measurement of how well an object can resist the transfer of heat. Put more simply, it is the insulation rating. The higher the R-Value the better insulation an object will provide. For example, our uPVC windows and doors have a minimum R-Value of 0.74, compared with thermally-broken aluminium joinery which has an R-Value of just 0.5. This means our uPVC windows has 48% better insulation than thermally-broken aluminium.

  • How long is the warranty?

    Our joinery is tested to meet New Zealand and Australian standards. uPVC windows & doors are manufactured by Starke in Auckland and carry a comprehensive 10 year manufacturer’s warranty. The warranty is subject to correct installation as outlined in the Installation Details Manual available from us. For full details please read the Starke Care, Maintenance and Warranty Guide.
