They have independent drainage cavity and steel lining cavity to completely isolate the water and steel lining, maximize the service life of doors and windows and effectively improve the effects of heat preservation, heat insulation and sound insulation.

The profile formula selects high-quality green environmental protection raw materials that are non-toxic, harmless, tasteless and pollution-free, and reasonably adds flame retardants to make the profile healthy, safe and green.
