Aluminum Casement Window Soundproof Thermal Break –

Product Overview

Engineered for modern apartment complexes, this aluminum alloy swing casement window integrates soundproof, thermal preservation, and wind resistance capabilities into a single frame system. Constructed from 6063-T5 aluminum alloy with multi-chamber profiles and a polyamide thermal break, these windows achieve a sound reduction of up to 35 dB and a U-value of 1.8 W/m²·K. Certified to EN 14351-1, the design features EPDM weatherstripping and a 5+12A+5 mm double-glazed unit for consistent performance in high-rise residential environments.

Frequently Asked Questions

What is the actual sound reduction performance of this window in real-world apartment conditions?

Laboratory tests show a weighted sound reduction index (Rw) of 30-35 dB depending on glass configuration. For street-facing apartments, the 5+12A+5 double glazing with laminated inner pane reduces traffic noise to a comfortable indoor level. Field performance may vary by 2-3 dB based on installation sealing and wall construction.

Can the thermal performance be improved for extreme climate zones?

Yes. Upgrading to a 70 mm frame depth with 6+15A+6 low-E double glazing and argon gas fill can lower the U-value to 1.4 W/m²·K. This configuration is suitable for cold climates (e.g., northern Europe or Canada) and meets passive house standards for residential windows.

Is this window suitable for installation in a 30-story apartment building with high wind loads?

Yes. The standard frame design is tested to wind load resistance Class C5 (EN 12210), which corresponds to a pressure of up to 2000 Pa. For buildings above 20 floors or in hurricane-prone regions, we recommend the reinforced 70 mm profile with additional corner brackets, achieving Class C6 (2400 Pa).

What is the minimum order quantity and lead time for a typical apartment project?

MOQ is 50 units for standard sizes and finishes. Lead time is 25 days for production after sample approval and deposit, plus 10-15 days for sea freight to most destinations. For urgent projects, express shipping (air freight) can reduce total lead time to 15 days.

How is the window packaged to prevent damage during long-distance shipping?

Each window is individually wrapped with PE foam and corrugated cardboard, then placed in a wooden crate with foam corner protectors. Crates are stacked with interleaving plywood sheets. For container shipping, windows are loaded vertically to minimize glass breakage risk. We provide photos of packaging before shipment for approval.
