Key points to be considered in the preliminary planning:
- Height planning of the shell
- Interior and exterior thicknesses
- Consider thermal insulation
- Design of the slope

Product certificates cannot replace the following three essential requirements for the successful installation of barrier-free thresholds:
ACO supports you in all of these points.
In public buildings, barrier-free entrance doors are always provided.
The transition from living areas to roof terraces, balconies or loggias, which should be as level as possible, as well as the stepless building entrance area are critical construction points that must be carefully detailed, as moisture damage can occur very quickly due to weather influences (driving rain, snowbag formation). Already in the early planning phase, all boundary conditions should be taken into account, e.g. interior and exterior construction thicknesses, ceiling offset and slope.
The barrier-free transition from buildings to the outdoors often leads to conflicts with technical regulations. There are tried and tested solutions for this, but they do not conform to all points of the directive: By laying external drainage channels parallel to the door, protection against moisture can be fulfilled without a major difference in height between the external and internal levels.
The demand not only contradict the formulated requirements for barrier-free construction, but were and are equally regarded as impractical by numerous architects, property managers and flat users. Large threshold heights are undesirable in many circles and are not implemented.
All experience gained in reducing the connection height from 15 cm to 5 cm should be used. Procedure for planning barrier-free door thresholds:
Evaluation of a planned threshold formation:
Evaluation of the surface drainage:
Grating:
Barrier-free lower door stops and thresholds:
