Windows for tropical South-East Asia: ventilation first
In the tropical market the window is ventilation equipment first: the brief is cross-breeze that runs all year, monsoon protection without closing the room, salt air on the hardware, and an insect load that makes the screen a first-class line item. The schedule that works is the sliding door with its integrated screen track, the tilt sash for controlled opening, and the glass-roof and louvered lines that keep the outdoor room usable through the wet season — factory-assembled, SGCC where Singapore applies, on a 30–45 day schedule.
The brief is airflow, not just glass
The tropical house is designed to breathe: openings on opposite faces, cross-ventilation through the room, and the opening left open for weeks at a time. That changes what the window has to do. The sash opens and stays open through the wet season — which puts the screen, the gasket and the drainage at the front of the specification, ahead of the finish. A window that is beautiful closed but fails open is the wrong product for the market, which is why the ventilation lines lead the regional schedule.
The screen, as a line item
SC-40 is the screen door family: fibreglass or stainless mesh in 16–19 gauge, in a slim frame matched to the door range it pairs with, on 316 stainless hardware rated for the salt fog. The sliding leaf follows the SD-50 slider on the same track logic; the hinged leaf matches the FD-60 french handing; the marine variant takes the full coastal schedule. The spline channel comes out for re-meshing, and the service kit packs in the crate — on a tropical schedule the mesh is a consumable, and the replacement should take minutes, not a visit.
Monsoon: drainage and the gasket line
The rain case is vertical, heavy and sustained. The lines on the regional schedule answer it with concealed drainage and a continuous gasket — the sash compresses the seal all round in the locked position, and the water that does get past runs out through the built-in drainage instead of standing in the track. The outdoor-room lines carry the same logic: the SR-200 sunroom packs a concealed gutter with the downpipe routing in the frame, and the LP-120 louvered pergola closes on its own under the rain and wind sensor, which is the difference between a terrace that works in the wet season and one that is closed for the month.
Coastal hardware, development-scale drawings
- Salt-fog hardware and the powder-coat schedule on every exposed elevation — the 316 line on the screens, the coated profile on the frames.
- SGCC certification where Singapore is the market of record; the local standard applies for Malaysia, Vietnam and the rest of the region.
- One shop-drawing package covering a whole development — the townhouse project specifies the repetition once, and the schedule prices it as a run.
- Lead time at 30–45 days on the standard schedule, screen, sunroom and pergola packages factory-assembled to the same quality gate as the window line.
Questions
The 316 grade is the salt-fog line: the coastal humidity cycle attacks 304 at the screw heads, and the screen is the most exposed hardware on the house.
