Innovative NZ-made Windows and Doors

Stärke have been manufacturing windows in New Zealand since 1987. When the limitations on changes to the existing extrusions grew increasingly tiresome, Stärke took it upon themselves to go around the world to learn from the best and returned to New Zealand to develop outstanding windows and doors with New Zealand in mind.

Having thrown out the rule book, Stärke made their own profiles and re-designed aluminium windows from scratch. The end result delivers innovation in the product itself, as well as in how it is made. 

Stärke have partnered with European market leaders to deliver a Premium Thermal Suite. The range includes Tilt & Turn Joinery and Stärke is the only prime die holder in NZ to offer thermally broken aluminium Tilt & Turn joinery through the fabricator network. No more waiting months for overseas shipping, the suite is fully manufactured in NZ and available nationwide.

Stärke pride themselves on:

  • Easy installation and added cladding protection with 25mm flanges.

  • Invisible fixings, no frame leakage and extra durability with solid block spigot joints.

  • Bigger windows with larger glazing pockets with stronger aluminium extrusions.

  • Standardised suite fits with architectural and commercial suites

  • Faster turn-arounds with full service manufacturing.

  • Flush sills on all sliders.

  • Bold modern aesthetic with flat profile across all range.

  • European class with thermally broken tilt & turn joinery available nationwide.
