|Mulity-chamber plastic upvc profile for casement windows and doors|
The advantages of 70 open plastic upvc profiles doors and windows series:
（1） The main section bar with a six-cavity structure has good thermal-insulating and energy-saving effts, which is one of the most high-end section bar systems in the current market.
（2）It applies independent drainage cavity design to improve the drainage performance of finished windows.（3）It can be designed into in-swinging casement windows, inward tilt-turn windows, fixed windows, etc.
（4） Through connection materials, it can form connection in any angle.
（5） It can be equipped with three-layer and double-layer hollow glass at large intervals.
（6）With simple, utility and highly operable technologies, it is suitable for industrial production.
（7） 4-level air tightness, 3-level water tightness, 4-level wind pressure resistance and 8-level thermal insulation.
