Although there is hardly any doubt that the door threshold is a useful component that significantly improves the energy efficiency of a house, it is often a stumbling block in everyday life. Threshold-free transitions (Barrier-free doorsteps) therefore not only mean an increase in comfort, but are also for people with physical limitations even essential.
In newer buildings today there is a fundamental attempt to avoid any obstacles. As a rule, interior doors no longer have any thresholds, and balcony doors or French windows on the terrace are installed at ground level as far as possible. Classic door thresholds are mostly necessary only on house doors.
Install the appropriate door seal (Barrier-free doorsteps)
It is not for nothing that the topic of door sills is often referred to as seals. Doors are usually provided with an elastic rubber seal at the stop and at the threshold. This ensures that the door lies firmly in the door frame and closes airtight.
Incidentally, it doesn’t matter whether you have an entrance door made of aluminum, plastic or wood, because the entrance door seal always works on the same principle. A distinction is made, however, between stop seals and threshold seals.
Stop seals
For doors and windows, the rebate seal is always located where the sash and door frame touch – at the stop of the respective profile. In this way, any gaps between fixed and moving components are safely closed.
Threshold seals
A threshold seal is used to seal the bottom of the doors. This is particularly useful if the height between the corridor and the outer entrance area is being adjusted at the same time.
Barrier-free and tight doorsteps- is that possible?
But what happens to the door base seal when the new entrance door is made barrier-free?
The most modern solution are entrance doors with magnetic seals. Magnetic profiles in the floor and matching strips in the door ensure excellent tightness, as the magnets in the door pull the counterparts in the floor area upwards. However, magnetic floor seals are also noticeably reflected in the price of the front door.
