Upper edge of finished floor

from Wikipedia, the free encyclopedia

The upper edge of the finished floor ( OKF , OKFF or OKFFB for short ) is a frequently used dimensioning specification from the building industry . It is the height coordinate for the finished floor of a storey including the floor structure (e.g. thermal and impact sound insulation, screed) and floor covering (e.g. tiles, parquet). It can take place in absolute coordinates ( meters above sea level (m. Above sea level) ) or relative coordinates (for example above ground floor).

The height of the raw ceiling is called the OKR (upper edge raw ceiling or raw floor).
