Dress wooden beams with different materials


For various reasons, disguising wooden beams may be recommended. Uneven surfaces and inclined support beams can be straightened, unsightly surfaces can be hidden or the look is adapted to the architectural style. In addition to wood cladding and multi-purpose plates made of fibers or gypsum are common.

Wood on wood

If the beams are still made of wood, a shuttering is required. For beams embedded in the wall, panels can also be laid in bridge form over the visible side of the beam. They are either connected to the masonry abutting or mounted on the beam.

Freestanding support beams are boarded all around. If no opaque paint is planned and the natural grain and texture is to remain, miter joints at the corners are the most visually elegant solution. Glue joints are preferable to screws and nails, so that a later processing such as grinding is easily possible.

A substructure, on which cladding elements are attached to the beam, simultaneously assumes the function of spacers. You have to compensate for bumps on the beams. When cladding horizontal ceiling and floor joists, this function is taken over by the side shuttering boards.

Multipurpose and fiberboard

If the wooden beams need only be preserved for static reasons, but are to be adapted as best as possible to the remaining surfaces of the masonry and ceilings, panels made of multipurpose panels are practical. Possible candidates:

  • MDF
  • OSB
  • Rigips
  • pressboard

For free-standing beams, the increasing cross section must be taken into account. In general, a cladding can also be created without direct contact with the wooden beam. The plates are only attached to the endpoints and "stand" like a box around the bar.

Ventilation and condensation

Every cladding of wooden beams must be ventilated. Therefore, solid and raumabschließende substructures such as wood blocks or hardening liquid attachment aids such as construction foam or cement are not suitable. Covered wooden beams remain a "living" building material and their breathability must be maintained.

Tips & Tricks

With any type of disguise, you should think about how much effort you can take to see how your beam works. Therefore, a potential inspection opening, which can be opened with a few screws or consists of a small flap, is a useful addition to your design.
