Inspection opening closure

Buildings must have safe escape and rescue routes according to the Model Building Regulations (MBO) so they can be safely evacuated. The design of installation ducts and particularly of inspection closures are regulated by the Model Directive on Technical Requirements for Fire Protection with Respect to Conduit Systems (MLAR).

There are four essential requirements for closures of installation ducts:

  • Permissible types of wall
  • Non-combustible
  • Fire integrity
  • Smoke-proof

Therefore, select and design closures for installation ducts with building components that were specifically designed and approved for that purpose. With regard to the common requirements for installation in wall types, non-combustibility, fire resistance and smoke-proofness, these are inspection closures specifically approved by the building authority as inspection closures, such as the inspection closures of PRIORIT.
