120muti-cavity external fenestration series

Flat frame inside and outside, seamless welding window sash, rounded comner design of R7, seamless welding built-in comer code impact process The whole window adopts a hidden drainage system to enhance the drainage perfommance and prevent water seepage It is made of 6063-T5 aviation-grade silicon titanium aluminum alloy, which has high strength, high toughness and is not easy to deform Highquality surface treatment, better anti-oxidation effect, can withstand weather for 20 years Vertical isothermal design, three seals, and automotivegrade styrofoam strips.

• The interational PA66 heat insulation strip greatly improves the sound insulation, heat insulation, waterproof and windproof performance
• The hollow tempered glass has sound and heat insulation, no fog, safety, and light transmittance can be improved by several times
• The pin injection process makes the profle splicing stronger and effectively prevents defommation, water leakage and other problems caused by impact or extrusion
