The door body adopts high-quality aluminum alloy frame and embedded thermal insulation layer, which effectively blocks the external temperature change, keeps the indoor temperature stable, and is energy-saving and environmentally friendly. At the same time, the door panel design has excellent sound insulation effect, which can greatly reduce the noise transmission and improve the privacy of the space. It is suitable for hotels, offices, residences and other environments with high noise control requirements. Its unique spring structure ensures that the door body closes automatically and fits the door frame tightly, further enhancing the sealing and sound insulation performance. Aluminum alloy material is not easy to oxidize, has strong durability, simple and modern appearance, and is suitable for various decoration styles, which not only meets functional requirements but also adds space beauty.
