Stärke is the only end-to-end window and door joinery system supplier in New Zealand, with our own design, product suites, raw materials supply and powder-coating. We run our own fabrication shops, just to prove that we know what we’re doing. We’ll then look after installation, and be right there for the lifetime of the product with our aftersales care team.

Stärke has it’s origins in grass-roots NZ construction, being a product of two family businesses who have been in the aluminium window fabrication game since the early 1980’s, and who were builders before that. Early in 2013 we began to build on that rich heritage by starting something truly monumental; designing a new set of window suites from the ground up, specifically for the New Zealand market; and specifically for the 21^st century consumer. We are driven by one goal, better windows for Kiwis, for less. 

The modern, flat faced frame for the bold look.

The flush sills for that seamless design flow.

The hidden spigot joints eliminating unsightly screw holes.

It’s all there with Stärke. And our suites don’t just have a pretty face – we’ve put effort even where you can’t see, with thicker, stronger profiles for extra durability, design features which save time, money and gain fabrication efficiencies. That’s why we can offer a 10 year warranty on all of our work.

We make it easy to buy from us, with shop drawings, design assistance, and a customer service culture dedicated to you.

We care about the future and are passionate about embracing better thermal performance. Talk to us about it.

We use world-class software with built-in R-value calculations; we are ready for better thermal performance requirements.

We have simplified everything with just four suites which work together for unlimited flexibility.

We grow people, from staff, to suppliers, to customers and everyone in between.

For all those people, and last but not least the Kiwi homeowner, Stärke is a window to a better world.
