Fire-protective render systems and boards

Due to their thermally insulating effect, fire-protective render systems increase the fire-resistance duration of the clad components. The render system consists of a dry mortar, which is mixed with water and applied to steel or concrete members in one or multiple layers, and a bonding agent.  A rigid thermally insulating layer is created.

Regulatory framework

DIBt grants national technical approvals (abZ) for fire-protective render systems which significantly deviate from DIN 4102-4 in their fire behaviour or DIN 18550 with regard to their composition.

For fire-protective render systems that are not fully covered by EN 998, DIBt can also issue a European Technical Assessment (ETA).

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).

Please feel free to use the template 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.
