Point supported vertical glazing
With point supported glazing, the glass pane is mechanically fixed to the substructure either via point fasteners installed in drilled holes or via clamps (edge clamps). Point supported glazing is used in facades, as canopies or as balustrades in outdoor and indoor areas. The point support leads to high local stress concentrations in the glass pane, which must be taken into account in the design.
Regulatory framework
Point supported glazing is executed in accordance with DIN 18008-3. For construction techniques which deviate significantly from these provisions, DIBt grants general construction technique permits (aBG). For products used in the construction technique which are not covered by harmonised European standards, DIBt grants national technical approvals (abZ). European Technical Assessments (ETAs) can also be issued for such products.
Please also note the relevant provisions of the federal states following MVV TB, A 1.2.7.

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).

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.
