The production of a substructure for plasterboard

When removing or converting wall surfaces, you have several options. Often, plasterboard is used to level walls and cover ceilings or closets. This often requires a substructure with the correct spacing.

The substructure made of wood or metal

A substructure is especially needed for those ceilings or walls that are not suitable for direct gluing with plasterboard. These can be, for example, extremely uneven masonry walls, for example in old buildings. It may also be necessary to build a stable substructure if electrical installations or additional insulation are to be included. The substructure thus fulfills several functions:

  • It should provide a straight and stable surface for the plasterboard even on very uneven walls.
  • The substructure creates space for additional insulation materials and possibly still to be carried out electrical installations.

The distances of the strips for the later attachment of the plasterboard

The spacing of the individual strips for fixing the plasterboard always depends on the size or the width of the plasterboard used. In any case, the distances should be chosen so that the edges of the plates are always centered on a bar. Two plasterboard should always meet on the middle of a bar. Only then can they be optimally fastened. If necessary, and depending on the size of the plasterboard used additional strips must be attached to make the fittings in the middle of the plate can. Always remember that the maximum screw clearances should not be exceeded. These vary depending on the size of the plasterboard used.

The construction of a substructure for the plasterboard

There are different types of substructures. You have the choice between a substructure made of wood and a metal, which allows a subsequent screwing of the plates using fine threaded screws. In a substructure made of metal is usually the installation of a kind of metal frame with mounting option for the plasterboard. Such a metal framework is also used when creating partitions. Alternatively, you can also attach several wooden slats to the wall. As a rule, you start each with a horizontal bar on the ceiling and on the floor. Between these two strips you then attach several vertical strips. These plates are later attached to the plates.

A few tips on making the substructure

For the production of the substructure use sufficiently strong beams, which ensure a good stability. When fastening, use sufficiently strong screws. Fix the beams to the wall with dowels. Remember that the joints of the plasterboard must always lie on a bar or on a beam. When working alone, it is best to use so-called one-man plates for attachment to the substructure.
