subceiling

The opening in the roofing must only be as big as to allow the subceiling or protection against trickling matter to be provided in the roof superstructure (see also Fig. 12).

3. Building-in of Roof Superstructures Rolf Becher 1993

It is advantageous when the surfaces of the trussed purlin and lintel transom are located at equal height which provides for a uniform room height when fixing the subceiling.

If a wooden beam ceiling is to be protected against trickling matter only, the subceiling (protection against trickling matter) may be made of boards planed on one side, of particle board or other material.

2. The Wooden Beam Ceiling Rolf Becher 1993

If purlin roofs have no valley beams, wooden beams must be built in for fixing of the subceiling.

In order to make the subceiling as light as possible, it is recommended to use faced particle boards.

Fixing to the trussed purling is necessary to prevent any displacement of the wooden beams or lift-off when the subceiling is nailed from below.

The subceiling may also be fixed to the bare ceiling as false ceiling.

1. Purpose of Ceilings Rolf Becher 1993

The structural components of bare ceiling, top ceiling and subceiling described therein need not exist with any wooden beam ceiling.

2. The Wooden Beam Ceiling Rolf Becher 1993

The visible part of the trussed purlin in the subceiling can be ground and painted or covered (faced).

- bare ceiling (supporting and stiffening structure of the ceiling) - top ceiling (floor construction on the bare ceiling) subceiling (covering the bottom side of the bare ceiling).
