You're definitely talking about polyurethane caulk, that thing is only used for caulking, fixing air is a strong point, fixing the door is not good. Or do you have to fix it with something special.
It should be the same, it is all polyurethane, and it is also used for filling and gluing. If there must be a difference, the styrofoam used for fire doors is added with flame retardant ingredients, and the anti-theft doors are not added. (That's how I understand it).
What do you mean by that? How can you directly add foaming agent to the security door?
You can add it yourself! After you add foam, the lock bolts up and down, left and right inside the anti-theft door will not move, and the anti-theft door will be invalid!
The strength of cement pouring is large, and the foaming agent is trouble-free.
