uPVC Windows Built for Sydney Conditions
Six frame styles, all manufactured from European multi-chamber uPVC profiles rated for insulated glass units up to 44mm thick.
Casement Windows
Side-hinged so the sash swings clear of the opening, a casement gives you the whole aperture for airflow and an uninterrupted view when open.
From $2,109
Casement Windows in detailTilt and Turn Windows
The signature European window: one handle, two modes. Tilt the sash inward at the top for secure background ventilation, or turn it a further ninety degrees to swing fully open.

Tilt and Turn Windows in detailAwning Windows
Top-hinged so the open sash forms a small awning over the opening - which is exactly why they can stay open through a Sydney downpour.
From $1,776
Awning Windows in detailSliding Windows
Horizontal operation within the frame, so nothing swings into the room or out over a walkway. The practical choice where space rules out a casement.
Sliding Windows in detailFixed Windows
No sash, no hardware, no gap to seal - which makes a fixed window the best thermal and acoustic performer in the whole range, and the cheapest per square metre.

An angled multi-panel configuration that projects beyond the wall line, adding usable floor space and a wide outlook to the room behind it.

Choosing window types for a unit block
Most Sydney unit blocks were built with aluminium sliding and awning windows. Replacement is the chance to choose the right style for each room rather than copying the old one. Casement windows open the whole sash for airflow and seal hard against a gasket, which makes them the quietest and least draughty option for bedrooms facing a road. Awning windows can stay open in the rain, so they suit bathrooms and kitchens. Tilt and turn windows open inward, so both sides of the glass can be cleaned from inside, which matters on the third floor and above. Sliding windows suit openings beside walkways and balconies, where a sash swinging out would get in the way. Fixed windows give the best performance of all where no ventilation is needed. Where a strata building needs a uniform facade, we keep the external look consistent across every unit even when the opening styles change inside.
What makes a window perform in an apartment
Three things decide how a replacement window performs: the glass, the frame and the seal. Double glazing with a Low-E coating chosen for each elevation controls heat; acoustic laminated glass deals with traffic and aircraft noise. The frame must insulate rather than conduct heat, which is why we use multi-chamber uPVC or thermally broken aluminium instead of standard aluminium. Then the sash has to close hard against a continuous seal. Most complaints about old windows (draughts, whistling, condensation, noise) come from the seal rather than the glass. Every proposal lists the WERS rating of each window type so the committee can compare suppliers.
Safety and security on upper floors
In a NSW strata building, openable windows where the floor is 2m or more above the ground and the opening is less than 1.7m above the floor need a window safety device that limits the opening to 125mm. We fit compliant restrictors to new windows as part of the job and record them in the handover documents; see our window safety devices guide. Ground and first-floor windows get multi-point locking that engages the frame at several points, and laminated or toughened glass where the building code requires safety glass.
Finishes, maintenance and lifespan
uPVC comes in white, colours and woodgrain finishes and does not need painting. Thermally broken aluminium is powder coated in almost any colour, so it can match an existing facade. Near the coast, uPVC does not corrode, while aluminium needs a coastal-grade finish and an occasional wash. Day-to-day upkeep for both is a wipe of the frames and a check that drainage slots are clear. Hardware is adjustable, so a sash that drops over the years can be reset rather than replaced. Every window carries a 10-year product warranty and a 6-year installation guarantee.
