Description
Technical Field
[0001] The utility model relates to the technical field of rolling shutter doors, in particular to a fireproof rolling shutter door with sound insulation and noise reduction. Background Art
[0002] Fire shutter doors with sound insulation and noise reduction are mainly used in places that need to have fire protection functions and control noise transmission. Fire shutter doors can be used as fire isolation equipment in emergency situations, and play a role in sound insulation in normal times to avoid noise interference. Transportation places such as stations and airports need to control noise to ensure the comfort of passengers, and also need fire prevention measures to ensure the safety of people and property. Fire shutter doors with sound insulation and noise reduction can meet these needs.
