Your shiny new aluminium window could be LESS energy efficient than a 50-year-old timber one 😳

Here’s what the energy ratings say:
🪵 Old timber, single glazed: 3.5–4 ★
🔩 New aluminium, single glazed: just 1 ★ for cooling and 1 ★ for heating
✅ uPVC double glazed: 6.5–7 ★

Swapping old timber for cheap single-glazed aluminium can actually make your home harder to heat and cool, and that shows up on your energy bill 💸

Our pick is uPVC double glazing. If that’s not an option, thermally broken aluminium is the next best choice.

Freezing in winter, cooking in summer? It might be your windows. 🥵🥶

Up to 40% of a home’s heating energy can be lost through windows, and up to 87% of its heat gained. The fix depends on where you live, so we made a state-by-state guide 👇

✅ The right glass for your climate
✅ An energy-efficient frame, not standard aluminium
✅ Bushfire and cyclone requirements covered

Watch to the end, then send it to someone who’s building or renovating 🏡

Tilt & turn window won’t close? Don’t panic 👇

It’s one of the most common calls we get, usually on a weekend. The sash has slipped into the wrong position, the corner is hanging out, and the window just won’t shut.

The fix takes 10 seconds:
1️⃣ Press and hold the mishandling device (the small lever on the side of the sash)
2️⃣ Turn the handle UP while holding it
3️⃣ Push the corner back in and close the window

Then turn the handle down, and it’ll work perfectly again ✅

Save this so you have it when you need it, and send it to anyone with tilt & turn windows 🔖

Still stuck? Send us a DM or give Windows Factory a call, and we’re happy to help.

They’re just windows. What’s the big deal?

Well… everything. 👀

Same space. Completely different feel.

That’s what the right windows can do.

Our client spent $30,000 on new windows… and here’s what they regret 😅

They regret waiting so long.
They regret putting up with draughts, street noise, freezing winters and hot summers for years.
They regret thinking new windows wouldn’t make that much of a difference. 🙈

And most of all… they regret not doing it sooner.
Because it’s not just about new windows. ❤️
It’s about waking up in a quieter home.
Feeling comfortable without constantly adjusting the heating or air conditioning.
Enjoying natural light without sacrificing comfort.

And finally having windows that look as good as the rest of the house. ✨
Sometimes the biggest home improvements aren’t the ones you notice first.
They’re the ones you feel every single day.
So, was it worth it?

We think the transformation speaks for itself. 🪟💚

Would you spend $30,000 upgrading your home’s windows, or does that sound crazy? 👀👇
