摘要： A door assembly, for an opening in a building, comprising a sealing assembly, wherein the sealing assembly is configured to seal a gap (36) between the rolling shutter door (4), the opening, and a surface of the building proximal the opening. The seal comprises a resiliently deformable member (48), and a sealing member (46), mutually positioned such that the resiliently deformable member co-operates with the sealing member when the rolling shutter door is in the closed position to seal the gap, which prevents or mitigates passage of sound, smoke, heat, and the like through the gap. The door assembly is preferably an acoustically-insulating door assembly.
