UPVC Sliding Window Double Glazed Soundproof – Energy

Product Overview

Engineered for apartment living, these sliding windows combine double-paned glass with a thermally broken UPVC frame to deliver significant noise reduction and energy savings. The multi-chamber profile and weather sealing meet EN 14351-1 standards for air and water tightness, while the 4mm/12mm/4mm glass configuration provides a weighted sound reduction index (Rw) of up to 35 dB.

Frequently Asked Questions

What is the sound reduction rating for the standard double glazed version?

The standard 4mm/12mm/4mm glass configuration achieves a weighted sound reduction index (Rw) of 30-32 dB. Upgrading to a laminated acoustic interlayer (e.g., 5mm/12mm/5mm with PVB film) increases this to 35 dB.

Can the window be customized with integrated blinds between the glass panes?

Yes, we offer a built-in blind option where aluminum or fabric blinds are sealed between the two glass panes. This requires a 24mm air gap and adds approximately 15% to the unit cost.

Are these windows suitable for ground-floor apartments with high noise exposure?

For ground-floor units near busy roads or commercial areas, we recommend the laminated acoustic glass upgrade (5mm+15mm+5mm) which reduces noise by up to 35 dB. The standard version is more suitable for mid-to-high floor apartments.

What is the minimum order quantity for custom-sized windows?

Custom sizes require a minimum order of 20 units per size and color. Standard sizes can be ordered in quantities as low as 10 units for sample testing.

How are the windows packed to prevent damage during shipping?

Each window is wrapped in protective film, then placed in a plywood crate with foam corner protectors. Crates are stackable and designed for container loading. We also include a moisture-absorbing silica gel pack inside each crate for long sea voyages.
