Frameless doors

Doors with invisible frames

The “invisible” frame system FLAT VD is fully integrated in the wall and therefore offers many options for wall design. As a concealed door that disappears in the course of the wall, as a ceiling-high variant with matching surface to the floor, or in the decor of the kitchen – the aim of this system is to integrate the door as a wall-designing element in the overall living space concept. In combination with the VARIA-Protect door leaf system with protective edging made of aluminum, there are almost limitless decor variants for the door leaf – whether glass, stone, or leather.


Wall design elements

Frameless doors open up new possibilities for room design. Why not have the door disappear completely in the room by matching it to the wall color, or use a mirror to add a special touch? Without a frame to get in the way, the door leaf alone acts as a design surface. We have a range of different variants available for you, including reverse-opening versions.

Concealed door frame with no loss of aperture width

Discover our newly developed FLAT Zero frame system for frame installations with no loss of aperture width in brickwork (0-14 mm drywall depending on the installation situation). With a door leaf thickness of 64 mm, this system is ideal for old buildings and renovations – but it is also a great choice for reverse-opening variants or ceiling-high doors with or without a top cross rail.

Concealed door frame, door opens inward

For standardized wall elevation and space design, we recommend the use of reverse-opening doors. For example, if you have several doors side-by-side in the entrance area, but for reasons of space they open in different directions into the connected rooms, then FLAT VD-IN is the perfect solution for you.

Project example

Architect’s house, Freudenberg/Germany

Implementing ideas with no restrictions. When an architect builds his own house, more than anything else he wants to realize all of his own ideas, with no restrictions. This goal was met with the aid of surface-flush, ceiling-high doors from ComTür. Thanks to the interplay between the “FLAT” frame integrated in the wall, the concealed hinges, the surface-flush escutcheons in the door leaf, and the elegant special shade DB 703, we were able to produce wall design elements that were perfectly integrated in the interior design concept of the rooms. “Good to know that ComTür has the perfect system solution for any building situation,” explained the architect who was carrying out the work.
