We designed, produced and constructed the door and window system for the Jiaxing Maternal and Child Health Hospital to meet the hospital's strict requirements for sound insulation, heat insulation, privacy and comfort. The project uses T-66 aluminum alloy profiles and high-performance system doors and windows, with hollow glass and special sealing structure to effectively block noise and heat, providing patients with a quiet recuperation environment. The final result significantly improved the hospital's diagnosis and treatment environment, creating a comfortable and private space for patients and medical staff, and reducing operating costs through energy-saving design. It has been highly recognized by the hospital and demonstrated our professional strength and service level in the field of medical building doors and windows.
