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.
National procedure
To prepare an abZ/aBG for your construction product, we need an application from you. We recommend that you contact us prior to doing so. Feel free to send us your enquiry informally via email to dibt(at)dibt(.)de or to the competent technical contact listed in the top right.
For a first assessment, please send us the following information:
- Description of the construction product and its intended field of use
- e.g. material, configuration, number of sizes, variants, dimensions
- e.g. use in walls, ceilings, interior construction, building services
- Description of the construction technique and its field of application
- e.g. design of walls, ceilings, elements, etc., and interaction of components
- e.g. application in foundation engineering, reinforced concrete construction, building insulation; as load-bearing or non-load-bearing component; under static and quasi-static loading; fire exposure; other environmental exposures
- Information regarding impact on regulatory concerns
- in particular structural integrity, fire protection, health and environment protection, sound insulation as well as thermal performance
- Explanation of need for an abZ/aBG
- Do you significantly deviate from the Technical Building Rules?
- Or do neither Technical Building Rules nor generally recognised technical rules exist?
- Contact details
- preferably email address and/or telephone number, as well as name, organisation/company, and postal address
We will then contact you to clarify the next steps.
If you already hold a DIBt approval and/or construction technique permit and wish to apply for an amendment, supplement, or renewal, please use the form provided 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.
