Forget what you know about windows.

Seriously. What if we told you the future isn’t just better insulation or sleeker frames – it is a completely different way of building and thinking about windows altogether?

Meet TWINDOW – the most advanced modular window system built for long-term durability, sustainability, and design freedom. This isn’t just another upgrade — it’s a genuine step change in how windows are made and maintained.

Here’s why TWINDOW is one of the most innovative window systems now available for New Zealand homes.

A Modular Concept: It’s Not One Window – It’s Two

TWINDOW is built around one simple but revolutionary concept: the inner window and the outer, weather-facing shell are separate.

• The interior core stays protected inside your home. It provides structure, holds the glazing, and is engineered to last for generations.

• The outer shell is the weather shield – taking the hits from UV radiation, rain, wind, hail, and coastal conditions.

Because the inside is never exposed to weather, it doesn’t degrade.
The outer shell? Replace it whenever needed — easily, without demolition.

The Result:
A window that lasts decades longer than traditional systems, with significantly less waste. No water damage, no UV degradation, no rot. Just solid performance, year after year.

Maintenance Without Mess – Just Swap the Outer Shell

Storm damage? Want to refresh your colour scheme in a few years?
No problem.

Instead of replacing the entire window (and often the surrounding wall), TWINDOW lets you:

• Remove the exterior shell

• Install a new one

• Keep the inner core completely untouched

That means:

• Lower lifetime costs

• Less waste

• Much easier renovations or colour updates

It is smart, simple, and sustainable — a win on all fronts.

Total Design Freedom -Your Window, Your Way

One of the biggest advantages of the TWINDOW modular window system is the ability to mix materials and finishes independently – inside and out.

Want a warm timber look inside? Go for it!

Prefer a low-maintenance, highly durable aluminium exterior? No problem!

You can even mix materials between the sash and the frame – giving architects and homeowners full creative freedom.

This makes TWINDOW ideal for modern, architectural builds as well as sustainable family homes looking for longevity and flexibility.

True Sustainability — Built In

TWINDOW doesn’t just claim sustainability – it is built into every layer:

• The Timber Interior – Locally sourced, certified, and not exposed to moisture, so there are no chemical preservatives needed.

• The Aluminium Exterior – Recycled, recyclable, and long-lasting.

• The Glass – Low-carbon, made with renewable energy and recycled shards.

• End-of-Life Design – When the system eventually reaches the end of its (very long) life, the components can be separated and recycled individually.

This is true circular-economy engineering — reducing waste, extending lifespan, and maximising material reuse.

Seamless Interior Finish

TWINDOW eliminates the usual timber glazing beads on the inside.
The result?

• Cleaner lines

• No visible joints

• A smooth, modern timber finish

• Better airtightness and better sealing

• Less risk of gaps, drafts, or moisture issues

This isn’t just beautiful – it’s functional.
The system delivers outstanding airtightness, thermal performance, and sound reduction.

Why Kiwi Designers, Architects, and Builders Should Pay Attention

TWINDOW is more than a European innovation — it’s a new direction for window technology in New Zealand.

It’s modular. It’s ultra-durable. It’s eco-smart from start to finish.

In a building industry where waste is common and replacement is often easier than repair, TWINDOW offers a smarter, future-proof alternative.

Ready to Build Better?

Whether you are planning a new build or upgrading an existing home, TWINDOW brings together sustainability, long-term durability, and elegant design in one advanced system.

If you want windows that last longer, perform better, and tread lighter on the planet – TWINDOW is the system to watch.
