Standard aluminium frames conduct heat and cold straight through the metal. Our multi-chamber uPVC profiles insulate the way European homes have for decades - keeping heat out in summer, in during winter, and street noise outside all year round.
- Frame U-value as low as 0.77 W/m²K - industry-leading thermal performance
- 50-70% less heat transfer than standard aluminium frames
- 5-6 chambered profiles from Aluplast, Kömmerling, Deceuninck, Plustec and Schüco
- Double or triple glazing, Low-E, acoustic laminated and toughened glass options

Made to measure, priced to match
Every window and door is manufactured for your exact opening, so an accurate price always starts with a free on-site measure. Whole-home and whole-building projects benefit from volume pricing, and flexible payment options are available so the upgrade fits your budget, not the other way around.

Trusted by homeowners and strata committees across Sydney
“I can't speak more highly of Windows Factory and have no hesitation recommending them. Replaced all windows and balcony door in a 3 storey townhouse with double glazing and soundproofing, a unique job with design challenges that WF completely handled. Their prices reflect the high quality product and they have a great team, with Josh leading tradies who are reliable, diligent and trustworthy.”
“I can't believe how much these windows have changed my life. We're in a south facing apartment with no direct sun at any time of day - lovely in summer but cold in winter. Now we have double glazed windows, we can run the heater for an hour and it stays warm instead of leaking out the windows. Josh, Anton and the team have been a joy to work with.”
“Thanks Anton, Josh and team. Great job on installation of our new windows. All went to schedule and results are grand. The main advantage is noise reduction with double glazing and window seals. Should have done this years ago.”
