Đồng Tâm Window
Cửa đi hai cánh mở quay
A two-leaf hinged aluminium and glass door opening to almost 90°, with a restrictor bar to stop the leaf hitting the wall. Multi-point locking plus twin gaskets give a tight seal, good acoustic and thermal insulation, and resistance to forced entry. It uses little space in operation, which is why it is common in low-rise buildings, villas and office entrances.
