Gapless ceiling - a solution that is implemented using the KROTT profile. When using a profile, the junction is smooth and clear, the solution is feasible at corners of any complexity. Installation technology with plasterboard and plastered walls is described in the KRAAB SYSTEMS technological maps.

The profile system KROTT is mounted only with plasterboard or plastered walls, it is not recommended to dock the profile with other systems: built-in cornices, track systems, light lines and others.
