Modern aluminium joinery is definitely having a moment. You’ve likely seen plenty of homes sporting brand-new, sleek frames, whether it’s through full replacement or insert double glazing. And yes, the modern look can be stunning. But here’s what many people don’t realise: if your existing timber window frames are in good condition, retrofitting them with high-performance SuperTherm™ double glazing can actually be the better option, especially when it’s done the Elite way.
Why Timber Retrofit Double Glazing Still Wins
1. Timber Is a Natural Insulator
Timber has a high thermal resistance compared to standard aluminium joinery. While cold aluminium frames (especially those that aren't thermally enhanced) conduct heat and allow cold transfer into your home, timber helps to retain warmth, naturally. Pair your existing frames with SuperTherm™ double glazing and high-performance draught seals, and you’ve got a system that can rival or outperform many new installations.
2. Keep the Character. Upgrade the Performance.
For older homes, bungalows, and villas across New Zealand, timber windows are more than just functional, they’re part of the design story. Timber retrofit double glazing allows you to preserve the original aesthetic while drastically improving comfort and energy efficiency. No compromises.
At Elite, we’re specialists in carefully restoring and upgrading timber frames to look and perform like new. That includes re-machining, finishing with fresh hardware, and installing discreet seals that don’t take away from the look but absolutely transform the performance.
3. New Seals & Hardware Make All the Difference
One of the biggest misconceptions is that older timber windows can’t match modern performance. But with the right draught-sealing systems and new, high-quality hardware, you’d be surprised how airtight and secure they can be. High-performance seals prevent heat loss, reduce noise, and minimise condensation. And with updated locks, latches, and handles, your windows won’t just work better, they’ll feel brand new too.
When Is Timber Retrofit the Right Option?
If your current timber frames are still structurally sound, a retrofit is not only more cost-effective than full replacement, it’s more sustainable and preserves your home’s architectural integrity. We’ll assess the joinery carefully and give you honest advice on whether it’s a good candidate for retrofit or if another option is more suitable.

Don’t Rip Out Quality Timber for Trend’s Sake
Before you jump to full replacement or aluminium inserts, ask yourself: Is this upgrade going to add to the value, warmth, and charm of my home or take away from it?
If you're lucky enough to have quality timber joinery, don’t replace it - enhance it.
