Aluminium Casement Windows
Ultra-slim casement windows with thermal break technology, custom sizing, and powder-coated finishes — manufactured in-house at our Kuala Lumpur facility.
Engineered for Malaysian Climate and Style
Casement windows represent the gold standard for controlled ventilation and weather sealing. Unlike sliding windows that only open halfway, a casement window swings fully open — directing the full breeze into your space. Our aluminium casement series features ultra-slim frames that maximise glass area, bringing more natural light without sacrificing structural integrity. Whether you're renovating a heritage bungalow in Damansara or fitting out a new condominium floor, we fabricate every frame to your exact measurement at our in-house Kuala Lumpur factory.
Every frame is extruded from heavy-gauge aluminium profiles — thicker than the standard catalogue stock used by most contractors — preventing the flex and warp that causes seal failure over time. Thermal break technology isolates the interior frame from direct outdoor heat, meaningfully reducing heat transfer into air-conditioned rooms. Double or triple glazing with low-E coatings completes the system, giving your home year-round comfort while lowering energy consumption.
Thermal Break Technology
A polyamide thermal barrier separates the inner and outer aluminium profiles, blocking heat conduction and reducing solar gain into air-conditioned spaces.
Custom Sizes & Powder Finishes
Non-standard heritage bungalow openings, trapezoid frames, and curved walls — all fabricated in-house. Powder-coat colours include charcoal, anthracite, deep green, and any RAL match.
Multipoint Locking Security
Heavy-duty multipoint locking hardware engages at three or more points along the frame, providing superior forced-entry resistance versus single-latch alternatives.

Frequently Asked Questions
What is the difference between casement and sliding windows?
Casement windows swing open on a hinge, allowing the full panel to open for maximum ventilation. Sliding windows move laterally and can only open 50% of their total area. Casement frames also form a tighter weather seal when closed, which is why they outperform sliding types in acoustic insulation and watertightness.
Can you fabricate non-standard sizes for heritage or older properties?
Yes — this is a core advantage of our in-house factory. We regularly produce frames for unusual heritage bungalow openings that don't match any catalogue size. Bring us your measurements and we'll fabricate to exact specification without compromise.
How long does a casement window installation take?
For standard residential installations (up to 10 windows), fabrication typically takes 7–14 working days from order confirmation. On-site installation for a full bungalow set is usually completed within 1–2 days. Quotations are provided within 3 working days of your measurement appointment.
