Aluminium Double Gla | Aluminum Window China

Product Overview

Engineered with 6063-T5 aluminum alloy frames and thermal break technology, these double glazed casement windows deliver enhanced thermal insulation for energy-efficient building envelopes. Argon gas-filled double glazing with low-E coating minimizes heat transfer, while integrated louver curtains provide adjustable light control within a sealed unit.

Frequently Asked Questions

What is the thermal insulation performance of these windows?

With a 5+12A+5 mm double glazing unit filled with argon gas and low-E coating, the U-value is typically ≤ 1.6 W/m²K. Using a 70 mm thermal break frame can improve this to ≤ 1.4 W/m²K, suitable for passive house applications.

Can the integrated louver curtain be replaced or repaired?

The louver mechanism is enclosed within the sealed glazing cavity and is not user-serviceable. However, the entire sealed unit can be replaced by a certified installer if the curtain or glass is damaged, without replacing the entire frame.

Are these windows suitable for coastal or high-humidity environments?

Yes. The 6063-T5 aluminum alloy is corrosion-resistant, and the powder coating finish provides additional protection against salt spray. For extreme coastal zones, we recommend anodized finish or marine-grade hardware.

What is the minimum order quantity for custom sizes?

For standard sizes, MOQ is 50 units. Custom dimensions require a minimum of 100 units per size and a lead time of 25–30 days after sample approval.

How are the windows packaged for long-distance shipping?

Each window is protected with EPE foam padding, corner cardboard, and shrink wrap. They are then loaded into plywood crates with wooden pallets, ensuring no movement during transit. Crates are stackable for container efficiency.
