1200 ×900 mm Main Window
The main outer frame is 1200 mm wide, 900 mm high and 80 mm deep. One top-hinged sash occupies the coordinated frame opening.
Top-Hung Vinyl Awning Windows
White uPVC members form the 80 mm-deep frame/sash assembly. Concealed galvanized reinforcing sections, corner joints and seals follow the same window fabrication reference.
The sash remains hinged at its upper horizontal edge while its lower edge moves outward. Two side friction stays and a low-center operating handle form the selected operating arrangement.
The glazing requirement combines 6 mm glass, 12 mm sealed airspace and 6 mm glass for 24 mm total. Glass support, edge clearances, beads and safety requirements are coordinated with the sash.

The main outer frame is 1200 mm wide, 900 mm high and 80 mm deep. One top-hinged sash occupies the coordinated frame opening.
The compact frame reduces the overall width and height while retaining the 80 mm depth basis. Its single sash keeps the same top-hung operation and side-stay layout.
The wider frame is 1500 mm across at 900 mm height. Its sash reinforcement, glazing support, hinges and stays are sized together for the complete window.
