Product advantages of European style inner casement window:
The biggest highlight of the Aluminum Alloy Casement Window glass produced by etaifeng is its exceptional energy efficiency and sound insulation performance. Aluminum Alloy Casement Window utilizes a low thermal conductivity thermal break structure, coupled with triple-layered Low-E glass, resulting in a very low overall U-value. This provides better insulation in winter and saves on air conditioning in summer. The inward-opening and tilt-and-turn design of Passive aluminum window Aluminum Alloy Casement Window is also particularly practical. Cleaning the glass is convenient when opening inwards, while maintaining natural ventilation when tilted inwards. It also prevents rainwater from entering, making it suitable for bedrooms, children's rooms, and offices.
