Screed on timbered ceiling

If the screed - ideally a liquid cement screed - is bonded to the timber joists by means of Schubfix connecting screws, the composite structure produced becomes statically highly effective. Load bearing capacity is tripled; owing to the extremely high stiffness (it increases by the factor 10 as a rule) proving the vibration resistance of the timber ceiling is a straightforward business. Depending on the construction, the timber+concrete composite floor structure may be covered with structure-borne sound attenuating matting followed by a dry screed which will provide a suitable support for the final floor covering (e.g. parquet , tiling, etc.).
