Eight casement and top-hung systems — the widest choice in the range, because this is the window that does most of the work in a Singapore house. A casement clears the whole opening rather than half of it, and seals by compression instead of sliding past. If quiet is the priority, this is the section to be in.
Bedrooms facing a road, where sealing decides whether you sleep. Living rooms where the whole opening should clear. Above a kitchen sink, where the handle has to sit low enough to reach. And on any elevation that takes rain, where a top-hung awning can stay open through a shower.
A casement clears the whole opening and seals by compression rather than by sliding past. What changes between the eight is which way the sash goes.
German Siegenia fittings and German HOPPE handles — 50,000 cycles, 10-year surface warranty. Hinges specified at least 50% above the sash's own weight. Quintus · Q2 — sash face 77.5 mm · frame face 100 mm · glazing 26 mm (5 + 16A + 5) · integrated 304 stainless screen. Profile dimensions for the other seven are being confirmed with the factory.
