Proudly Manufactured Locally. Built for Australia.
Step Inside the Spartan Factory.
When you invest in premium double glazing, you shouldn't have to wait months for a shipping container from overseas, and you shouldn't have to settle for mass-produced, imported frames that aren't designed for our climate.
At Spartan Double Glazing, every uPVC window and door is custom-manufactured right here locally. We control the entire process from the factory floor to your front door. Because Australia has some of the harshest weather conditions on the planet, we engineer every frame and seal specifically to withstand brutal summers and freezing winters.
Don't just take our word for it—see it for yourself. Watch our behind-the-scenes factory walkthrough below. See the precision, the heavy-duty machinery, and the expert craftsmanship that goes into custom-building your new windows before they ever reach your home. Built tough, built precise, and built locally.
