With classic door frames, many things are resolved at the end. With concealed door frames, the situation is different. They are part of the construction readiness and their installation must come at exactly the right moment.
Hidden door frames are installed when the construction opening is ready, but the final surfaces of the walls or floors are not yet finished. It is the correct timing of assembly that determines whether the resulting detail will be technically correct and visually clean.
The basic rule is simple: the hidden door frame is installed before the final surfaces of the walls and floors.
The reason is obvious. The door frame should be incorporated into the structure so that the wall and the adjacent layers fit exactly with it. If it were to be installed after the plastering or finishing of the floors, complications, compromises and often unnecessary extra work would arise.
Therefore, with concealed door frames, you need to think ahead:
The ideal time to install a concealed door frame is when the rough construction preparation of the opening is complete, but the final surfaces have not yet been applied.
In practice this means:
Only when these connections are resolved does the installation of the door frame make sense.
First, a building opening must be prepared in appropriate dimensions and quality. With concealed door frames, precision is essential because they work with minimal continuity and the final detail hides nothing.
The frame is installed in the prepared opening before the walls and floors are finished. At this stage, it is crucial to ensure that it is precisely plumb, level and at the correct height relative to the final floor.
After the door frame is installed, the wall is finished so that it seamlessly connects to its visible edge. This is where the quality of the resulting detail is decided.
Floors are only solved according to the finally installed door frame and the known height of the detail. It is necessary to monitor continuity, especially in the case of a threshold-free solution and a clean landing of the door leaf.
In bathrooms, wellness areas or other heavily used spaces, it is important to decide in advance how the cladding will connect to the door frame.
The door leaf, hardware and final adjustment come only after the wet and dusty processes are completed.
The plasterer or drywaller must know exactly what detail is to be created. With hidden door frames, there is no room for improvisation on the spot.
It is necessary to be clear about:
One of the most common mistakes occurs when the final floor height is not clearly determined during installation. For concealed door frames, this is a crucial detail that determines the height of the entire system.
If the floor height changes during construction and the door frame is already installed, the problem is then transferred to the door detail.
A specific chapter is bathrooms and other spaces with ceramic or stone tiles. Here it is necessary to determine in advance:
Additional solutions directly on site tend to be more complex and unnecessarily open up room for inaccuracies.
The door frame is installed too soon without confirming the floor or final wall surface.
The opening does not match the required dimensions or is not precise enough for the system to fit properly.
The installation of the door system, plaster, flooring and tiling is handled by each profession separately, without any jointly agreed details.
The wall is not precise enough in relation to the door frame, which is immediately visible with a hidden solution.
The continuity of the cladding, skirting board or floor only begins to be discussed once the door frame has been installed.
The best way is to address hidden door frames in the preparatory phase of the project and confirm all connections before installation.
This is where DORSIS technical support is important, helping with the coordination of details, consulting on solutions directly with the construction team, and ensuring that individual layers and professions are properly connected.
A hidden door frame requires a precisely prepared base and the continuity of other crafts. The sooner the technical solution is clarified, the smoother the implementation process and the final result.
When the construction opening is ready, but the final surfaces of the walls or floors are not yet completed.
Because it determines the exact height of the entire door system and affects the continuity of the bottom edge of the door.
Ideally not. The connection of the cladding to the hidden door frame needs to be resolved in advance.
Installation without knowledge of the final composition of the floor and without coordination of related professions.
We develop, custom-make and implement concealed door frames, including extra-high invisible doors to the ceiling and glazed variants, frameless building shells, all-glass sliding partitions, pivot doors and concealed LINUS skirting boards. Our products are a functional and design addition to commercial and residential interiors.
