Fire-resistant wall and ceiling systems (escape tunnels)

Non-load-bearing, fire-resistant wall and ceiling systems are used to delimit escape routes.

Regulatory framework

There are no conclusive technical rules for these wall and ceiling systems. DIBt grants general construction technique permits (aBG) for these applications. Testing and verification parameters are defined in light of the individual construction technique on a case-by-case basis during the permit procedure.

Application forms

National procedure

A national technical approval (abZ) and/or oder general construction technique permit (aBG) is granted upon application (see Model Building Code (MBO), Sections 16a(2) and18(2) and (4)). This also applies to amendments and supplements to, or renewals of existing approvals and/or construction technique permits.

No formal requirements apply.
