the ultra-wide multi-cavity heat insulation design, multi-channel sealing and multi-layer glass effectively form the overall and multi-channel barrier to resist heat;
super-strong heat insulation and ultra-low noise;
it is safer to adopt double hollow sandwich glass;
fully imported high-quality hardware, the heavy window sash can be easily opened and closed.
we focus on the perfect unity of performance and design sense, not only advanced in performance, but also excellent in design and visual performance.
