Structural sealant glazing
With structural sealant glazing, glass panes are bonded to frame profiles at the factory (primarily using silicone adhesive and with a linear adhesive bead). This prefabricated structural sealant glazing is then mechanically fixed to the substructure at the site.
This type of glazing is primarily installed in facades. Overhead installation is, also, possible. In addition, prefabricated structural sealant glazing is used for internal partitions. Here, too, the glazing is mechanically fixed to the subframe. For internal partitions, this glazing is often installed in combination with fire-resistant glazing. Prefabricated structural sealant glazing is also used in photovoltaics, where the glass is not held mechanically via the frame, but rather bonded to the profile, e.g. for solar modules with back rail bonding.
Regulatory framework
For glass panes bonded to a frame profile in the factory, a regulatory verification of fitness for use (e.g. approval) is required. DIBt grants national technical approvals (abZ) for these products. European Technical Assessments (ETAs) can also be issued for them. Regulatory verifications of fitness for use can also be required for construction products for fixing the bonded glass panes to the subframe if they are not otherwise regulated. The assembly of construction products (construction technique) is regulated via a general construction technique permit (aBG) or via specifications in the Administrative Provisions – Technical Building Rules (VV TB) of the federal states; cf., the common model MVV TB, in particular Section A 1.2.7.
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.
