Fasteners for rear fixing of facade panels

These fasteners are used for rear fixing facade panels to the subframes of external wall cladding systems. The load-bearing parts of the fastener are made of stainless steel. The deformation-controlled or torque-controlled fastener is inserted into a drilled hole or an undercut hole in the facade panel. The anchoring is achieved by mechanical interlock.

The facade panels can be made of mineral-bonded material (e.g. natural stone, cast stone, ceramic or fibre cement) or plastic-bonded material (e.g. HPL, polymethylmethacrylate or glass fibre reinforced plastic). The facade panel itself is just the base material for the anchor and not part of the construction product described here.

Regulatory framework

DIBt grants national technical approvals (abZ) for fasteners for rear fixing of facade panels. European Technical Assessments (ETAs) can also be issued.

Furthermore, DIBt grants general construction technique permits (aBG) for applications comprising these products for which there are no conclusive technical rules.

Technical rules

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.
