Premium uPVC double glazed windows and doors, manufactured in our 7-star Kilsyth factory to European standard and installed by our own trained team.
Full galvanised steel through every frame, never partial.
uPVC is a rigid, multi-chamber profile. Those sealed chambers trap air and insulate, where an aluminium frame conducts heat and cold straight through. That difference, called thermal bridging, is why the frame matters as much as the glass.
Every APS frame is reinforced with full-length galvanised steel for the strength of metal without the heat transfer. It won’t rust, warp, flake or fade, and it’s built for Australian UV, salt air and extreme heat.
Six things that come standard on every APS uPVC window and door.
Full-length galvanised steel through every frame for strength and long-term stability. No partial reinforcing.
Frame joints are hot-plate welded, not mechanically joined, so there’s no twisting, separation or air leakage.
Glass is fitted from inside the frame, improving both weather tightness and security.
German-engineered locks secure the sash at several points along the frame, not just one.
Two panes of Softcoat LowE glass, an argon-filled cavity and a warm-edge spacer bar as standard.
Made to AS 2047, glass to AS 1288. Kömmerling profile licensed by the Vinyl Council of Australia.
Heat moves through a window two ways: radiant solar heat through the glass, and conductive or convective heat through the frame and cavity. A uPVC double glazed unit is built to control both.
Standard APS double glazing carries a Weighted Sound Reduction (RW) of 32, with higher ratings available through acoustic glass. Every 10 dB roughly halves the noise your ear perceives.
Ear perceives ½ of previous noise
Ear perceives ⅛ of previous noise
Ear perceives 1/24 of previous noise
