Firebreak Doors & Shutters

The main functions of fire doors and shutters in the passive fire protection of buildings are:-

  • To maintain the fire separation of compartment walls but allow the passage of persons or objects
  • To maintain the fire separation in shafts or service ducts that penetrate compartment floors
  • To maintain the protection provided by walls forming protected routes for means of escape.

 

Doors and shutter assemblies are approved to:-

  • LPS 1056 Test and Evaluation Requirements for the LPCB Approval and Listing of Fire Doorsets, Lift Landing Doors and Shutter Assemblies. This standard is based upon BS 476:Part 20 Method for determination of the fire resistance of elements of construction (general principles), EN 1634-1 Fire resistance test for doors and shutter assemblies- Part 1: Fire doors or shutters and EN 81-58 Landing doors fire resistance test, or
  • EN 81-58 Landing doors fire resistance test, and/or
  • EN 1634-1 Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware. Fire resistance test for door and shutter assemblies and openable windows.

LPS 1056 isbased upon relevant BS or European test criteria and not only looks at the fire integrity and insulation (where applicable) but also includes reliability cyclic tests and grading.

Where insulation is marked as 0, this denotes that the insulation was not measured or that it could not be measured in accordance with the relevant standard.
