FAQ
Q: Q1: What are slim aluminium windows?
A: Slim aluminium windows use ultra-narrow frame profiles (as slim as 35mm visible width) to maximize glass area. They deliver a clean, minimalist aesthetic while maintaining structural strength through high-grade aluminum alloy and thermal break technology.
Q: Q2: Are slim aluminium windows strong enough for large openings?
A: Yes. Our slim aluminium windows are manufactured from high-strength aluminum alloy 6063-T5 with profile thickness of 1.8-2.0mm. They support large glass panels up to 2400mm in height, making them suitable for high-rise buildings and floor-to-ceiling installations.

A: Our slim aluminium windows feature a PA66 polyamide thermal break strip and can achieve U-values as low as 1.2 W/m²K when paired with Low-E double or triple glazing. This significantly reduces heat transfer, lowering heating and cooling costs.
