Pipe insulation products

Pipe insulation products are used to insulate heating distribution and hot water pipes as well as cooling distribution and cold water pipes in buildings in accordance with the Buildings Energy Act (GEG).

Regulatory framework

Pipe insulation products are mostly covered by European product standards and can be used taking into account the Administrative Provisions – Technical Building Rules of the federal states (VV TB, compare the common model MVV TB), DIN 4108-4 and the Buildings Energy Act.

DIBt grants national technical approvals (abZ) and issues European Technical Assessments (ETAs) for pipe insulation products not covered by the existing standards.

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
  • 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.
