Membranes for use as roof or wall underlay
Membranes for use as roof or wall underlay are installed underneath the roofing of pitched roofs or underneath the external wall cladding. They serve as an additional rainproofing measure to prevent the ingress of water or wind from the outside.
Regulatory framework
Membranes for use as roof or wall underlay do not require a regulatory verification of fitness for use or application, cf. MVV TB, no. 2.2.1.6.
In many cases, underlays are covered by harmonised standards DIN EN 13859-1 and -2.
As a Technical Assessment Body, DIBt can issue European Technical Assessments (ETAs) for underlays that are not or not fully covered by these harmonised standards based on European Assessment Documents (EADs) still to be developed or already existing, such as
- EAD 030218-XX-0402 Membrane for use as roof underlay
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.
