National certification (Ü marking)

Federal Industrialised Building and Off-Site Manufactured Houses Quality Assurance Association (Bundes-Gütegemeinschaft Montagebau und Fertighäuser e.V. – BMF) is a monitoring and certification body according to § 28 of the State Building Code of North-Rhine Westphalia (LBO Nordrhein-Westfalen) and the Construction Products Regulation.

The monitoring and certification body has the task of helping to ensure implementation of the protection objectives of the state building codes and the Construction Products Regulation. The protection objectives include:

  • Mechanical strength and stability
  • Fire protection
  • Hygiene, health and environmental protection
  • Safety of use
  • Sound insulation
  • Energy savings and thermal insulation

Timber panel elements

Compliance verification and compliance marking according to the new building codes of the federal states in Germany

In the state building codes of the respective federal states, the Ü-marking is required as verification  of compliance for certain construction products. According to the Construction Products List (“Bauregelliste”), this requirement also applies to wall, ceiling and roof elements clad or sheathed on both sides.

Based on the Guidelines for the Monitoring of Wall, Ceiling and Roof Panels for Panel Construction Timber Houses to DIN 1052, as a recognised body, the BMF conducts monitoring in the production facilities.

The manufacturer labels their wooden panel elements with the Ü-marking as visible verification of compliance with all requirements.

This BMF service is available to all manufacturers of this construction product and is not tied to association membership.

Dovetail Joint

To use the dovetail joint in load-bearing timber structures without additional connectors, they must be made in accordance with Approval Z-9.1-649 issued by the Association of Joiners (Verband HIGH-TECH-ABBUND im Zimmererhandwerk e.V.) Companies that have this approval confirm the compliance of the components produced with the requirements from the national technical approval through regular factory production controls and external monitoring. The external monitoring is carried out at least once a year by a test body recognised by the Deutschen Institut für Bautechnik (DIBt).

The BMF offers this external monitoring to its clients and awards the compliance marking as a proof of conformity. The certified company is thus entitled to mark the construction product with the Ü-marking.

European certification (CE marking)

With the recognition of the BMF as a European monitoring and certification body according to Article 43 of the Construction Products Regulation, we have created the option of also providing advice and support to our members for the European CE marking procedure for the construction products they produce.

Trusses Assembled with Punched Metal Plate Fasteners

Trusses assembled with punched metal plate fasteners offer substantial advantages based on their economic efficiency and the degree of preassembly. Different types of trusses can be produced effectively with these structures. The manufacturer’s factory production control is certified by BMF so that the CE marking can be attached to this construction product to EN 14250.

Sawmills

The BMF certifies the factory production control of sawmills. This is necessary to be able to trade on the European market with strength-graded timber for load-bearing purposes. The harmonised product standard for this construction product is EN 14081-1 on the basis of which the certification is performed.

After the timber has been cut to size, attention must be paid to important criteria during grading. In addition to mechanical properties and the wood moisture content, visual features are also checked. The assessment of knots, cracks and sweeps in relation to the quality of the timber helps with the classification for subsequent use.

In addition to the CE marking on the product, an accompanying document must be enclosed with the product on delivery. After the introduction of the European Construction Products Regulation, a declaration of performance must also be provided, on which the manufacturer confirms certain product characteristics.

Construction Kits for Buildings Made of Wood

Construction kits for buildings made of wood are specified in the ETAG 007. Among other things, these European guidelines define minimum requirements for structural design, thermal insulation, sheathing, fire protection and sound insulation.

On the basis of the ETAG 007, a European technical assessment (ETA) can be obtained through Deutsche Institut für Bautechnik (DIBt). The BMF advises and supports companies along their way to obtaining this approval. After the ETA has been granted the construction kit can be marketed within Europe with the CE marking.
