Sibu's heat, driving rain and security needs are hard on openings. We specify each window by how exposed it is — operation, glazing, frame grade and seals — then measure on site and draw for your approval before anything is ordered.
Where to start
Start from how the window should open, or the problem it needs to solve. Each opens the catalogue filtered to matching windows.
Popular choices
The window systems Sarawak homes ask for most — a good place to anchor your budget before you compare the full range.

What it costs
Windows are priced by area — the opening multiplied by the per-square-foot rate for the grade. Indicative only — excludes SST.
| Level | Scope | Indicative range |
|---|---|---|
| Essential标准级 | 6mm tempered · standard system, lock & seals | From RM 68 / sq ft |
| Signature舒适级 | Upgraded seals · insect-screen ready | From RM 98 / sq ft |
| Bespoke高端 | Laminated / Low-E · multipoint locking, heavy-duty | From RM 180 / sq ft |
Windows are priced by area — the opening (width × height) multiplied by the per-square-foot rate for the grade, supply and install. Indicative only, excluding SST — screens, non-standard glass and site conditions are confirmed at measurement, and the final figure follows the approved drawing.
Material options
A window is a long-term envelope decision, not a finish. Four choices decide how it performs in Sarawak — we match them to how exposed the opening is, not to a brochure photo.
A standard section for sheltered openings; a heavier, deeper section for exposed, high or wide openings so panels stay rigid and seals hold.
Clear for sheltered openings, tinted or coated to cut west-sun heat, tempered where breakage is a safety risk, laminated for security and storm performance.
Compression seals and correctly-set drainage channels so driving rain exits the track instead of pooling.
Fixed or retractable mesh that keeps openings usable for natural ventilation.
UV-stable matt, satin or textured colours — darker tones run hotter, so exposure factors into the choice.
Operation is matched to the opening, not to habit. Here is how we choose the window type for the job — the exact spec, glazing and frame grade are confirmed at your site measurement.
| Condition | Recommended construction |
|---|---|
| Tight space or balcony | Sliding — no projection into the room |
| Driving rain, air & acoustic priority | Casement — seals on compression |
| Ventilate through light rain | Awning — top-hung |
| Maximise light & view (no airflow) | Fixed / picture pane |
| Open a wall to the outside | Folding / bi-fold system |
No absolute claims: these describe how exposure and use guide the choice. Coated glass reduces solar heat gain, it does not eliminate heat; real performance also depends on correct installation, sealing and drainage.
Where it fits
The same systems scale from a condo bedroom to a shoplot facade — operation, glazing and frame grade change with the opening, not the standard we build to.
Sliding or casement sized for airflow and privacy, with mesh for mosquitoes.
Wide sliding or folding openings to the balcony or garden; fixed picture panes for light.
Small awning or top-hung units for ventilation with rain protection.
Heavier-grade frames, laminated glass and multipoint locks for wind and security.
Fixed and sliding shopfront glazing — specified and quoted with the facade work.
Sizing
Sarawak-standard openings, as a starting point — your exact opening sizes drive the area and are captured at a free site measurement.
| Layout | Typical reference size |
|---|---|
| Toilet / small厕所／小尺寸 | 600×600mm · ~3.9 sq ft |
| Bedroom standard卧室标准 | 900×1200mm · ~11.6 sq ft |
| Living / wide客厅／宽 | 1200×1500mm · ~19.4 sq ft |
| Master / large主卧／大 | 1800×1500mm · ~29.1 sq ft |
| Large span大跨度 | 2400×1500mm · ~38.8 sq ft |
Reference openings only. Windows are priced by area, so your measured width × height sets the figure — confirmed on site and fixed on the approved drawing.

Windows are priced by area — the opening's width × height multiplied by the per-square-foot rate for the grade, supply and install. Indicatively that runs from about RM68/sq ft at Essential (6mm tempered, standard system) to RM98 at Signature (upgraded seals, insect-screen ready) and RM180 at Bespoke (laminated / Low-E, multipoint locking). Excludes SST; screens, non-standard glass and site conditions are confirmed at site measurement and an approved drawing.
Casement windows generally seal tightest against driving rain because they close on compression; sliding suits tight spaces and balconies. Whichever you choose, we set the drainage channels correctly so water exits the track, and specify gaskets and seals for the exposure. Larger or more exposed openings get a heavier-grade frame with deeper sections.
Glass choice helps — tinted or coated glazing cuts west-sun heat gain compared with clear glass, and we factor the opening's exposure and a darker frame's heat into the spec. We don't claim it eliminates heat — it reduces gain — and pair it with the right frame and operation for airflow.
Yes — fixed or retractable mosquito mesh keeps openings usable for natural ventilation. It's specified per opening with the window, and the exact mesh and frame are confirmed at site measurement.
Both. ALUMAX supplies and installs aluminium windows across Sibu and the wider Sarawak under a confirmed scope. We measure each opening on site and draw for your approval before ordering, so the frames, glass and operation suit how exposed the opening is.
Aluminium is corrosion-resistant and weather-rated, so it copes well with Sibu's heat and rain with simple care — keep tracks and drainage paths clear and service the hardware as needed. It's not maintenance-free, but it asks far less than timber.
