Non-glued timber products and construction techniques, solid wood products

Non-glued timber products and construction techniques and solid wood products include timber products and construction techniques that are mechanically jointed, e.g. timber framing.

This work area also includes wall, roof and floor elements that are made without gluing, e.g. by connecting the boards by means of dowels, dovetail joints or other carpentry joints.

And finally, monolithic (cut from one piece) solid wood products are included in this field.

Regulatory framework

DIBt grants national technical approvals (abZ) for products

  • when they are not covered by the harmonised standards and
  • when they deviate significantly from the Technical Building Rules (cf. MVV TB, Chapter C 2) or
  • when neither Technical Building Rules nor generally recognised technical rules exist (e.g. innovative products).

European Technical Assessments (ETAs) can also be issued for products that are not (fully) covered by a harmonised standard.

For construction techniques comprising these products, DIBt grants general construction technique permits (aBG) when there is no conclusive technical rule for design and execution.

Application forms

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.
