In the end, there is no A47 Class B fireproof insulation and anti theft door

In fact, this is the name that has been used in many real estate bidding projects, and we have encountered a lot and explained a lot.

1. Fire prevention mainly refers to the fire integrity of the door, and it can be opened immediately after burning, and the fewer the lock points, the better.

2. Anti-theft refers to the safety of the door, the thickness of the steel plate, the anti-prying structure, and the more lock points, the better.

There is a conflict between the two, on the same door, it is difficult to achieve the full compliance of the inspection standards, you can require: fire performance to meet the requirements of A B, anti-theft: to meet the corresponding level of plate thickness requirements, insulation:

In fact, the fire door has achieved the effect of thermal insulation on the internal filler. Hope it has helped you.

There are three proof doors, but in many places are not recognized three proof certificates, now the fire door is the fire door, anti-theft is anti-theft, in the past, there was a fire and anti-theft door, now it can only be said that the fire door with anti-theft function.

Yes, usually the design of high-rise buildings needs three-proof doors, that is, fireproof, anti-theft, and thermal insulation doors.
