Fire-resistant joint sealing systems

Fire-resistant joint sealing systems serve to seal joints in fire-resistant components inside buildings or structural works (e.g. at the joint of two fire-resistant walls). The installed system prevents the spread of fire and smoke through the sealed joint, thus ensuring that the components continue to meet the requirements corresponding to their fire-resistance class.

Fire-resistant joint sealing systems are assembled from special filling and sealing products for joints.

Regulatory framework

DIBt grants general construction technique permits (aBG) for these applications.

European Technical Assessments (ETAs) can also be issued for corresponding construction products and kits.

Required verifications:

  • resistance to fire in accordance with DIN EN 1366-4.

Please contact DIBt before carrying out verifications for extended applications (EXAP) which are not already covered by the verifications named above.

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. The following information is needed: name and address of the applicant, description of the product and/or construction technique and its field of use or application, type of decision required (new decision, amendment or supplement to, or renewal of, an existing decision).

Please feel free to use the template below.

European Technical Assessment (ETA)

To start the ETA procedure, please submit the form below. We will then check if the prerequisites for issuing an ETA are met, i.e., in particular, if the product is not fully covered by an existing harmonised standard. If the prerequisites are met, we will check whether a European Assessment Document (EAD) covering the requested assessment scope already exists or still needs to be developed. If an EAD needs to be developed or amended, a complete technical file needs to be established before the procedure can begin.
