Introduction
40dB Soundproof Sliding Windows are high-performance aluminum sliding window systems engineered for acoustic insulation. They are ideal for residential or commercial projects located near roads, railways, and other high-noise environments.

Features
01
Acoustic Insulation
5mm+20A+5mm laminated glass effectively blocks sound transmission, delivering up to 40 dB noise reduction for a quieter indoor environment.
02
Thermal Insulation
Thermal break aluminum profile combined with Low-E coated glass reduces heat transfer, improving interior temperature stability and lowering HVAC energy consumption.
03
All-Weather Protection
Dual drainage chambers and inclined sills prevent rainwater penetration; EPDM sealing strips reduce cold air infiltration; laminated glass blocks up to 99% of UV rays.
04
Stable Structure
Marine-grade aluminum frame combined with hurricane-resistant laminated glass offers high impact resistance without deformation or cracking.
