WHAT ARE FIRE DOORS?
FIRE DOORS | NATIONWIDE
Internal fire doors create a passive fire safety system, protecting both domestic and commercial buildings from the spread of fire by confining it to a specific area for a longer period of time.
Installation of fire doors must be done correctly. The intumescent strip is just one of the key components in a fire door.
Running around the edge where the door meets the doorframe, it helps to trap the smoke, preventing it from spreading, as well as assisting in keeping flames from spreading beyond the door.
