FAQ Aluminium Casement Window
Do aluminium casement windows have good sound insulation?
Yes. With double-glazed or laminated glass, aluminium casement windows can significantly reduce outdoor noise, making them suitable for bedrooms, apartments, and urban environments.
Are aluminium casement windows waterproof and wind-resistant?
High-quality aluminium casement windows are designed with multi-point locking systems and compression seals, providing strong resistance to rain, wind pressure, and air leakage when installed correctly.
How do aluminium casement windows compare to sliding windows?
Casement windows seal more tightly than sliding windows, making them better for insulation, soundproofing, and air-tightness. Sliding windows are easier for wide openings, while casement windows excel in performance.
Can aluminium casement windows be customized?
Absolutely. They can be customized in:
Frame color and finish (powder coating, anodizing)
Glass type (clear, tinted, frosted, Low-E)
Opening direction (inward or outward)
Size and configuration
Custom sizing makes them suitable for residential and project use.
