What sets our doors with invisible frames apart
- Patented invisibility: The patented MET 56 frame is invisible because it disappears completely into the wall.
- Flexible planning: With our MET 56 frame, the decision on the right door model – whether a solid door, loft door or glass door – can be made flexibly at a later date.
- Concealed hinges: The door hinges are concealed in the frame – available in stainless steel or elegant black.
- Paintable frame: The frame can optionally be painted in the same colour as the wall for a harmonious overall look.
- Maximum minimalism: For an uncompromisingly flush appearance, a recessed handle can be selected instead of a door handle. This keeps the door surface completely smooth and takes the minimalist design to the extreme.

FAQs about optically frameless doors
A door with an invisible frame is a flush-mounted interior door that is flush with the wall, with the door frame completely disappearing into the wall. The frame is plastered over and is no longer visible once completed. This creates a visually frameless door, with the door leaf appearing as part of the wall.
The term ‘frameless door’ is often used colloquially. Technically speaking, it refers to a door with an invisible frame, where the frame is integrated into the masonry and plastered over.
In contrast to conventional interior doors with visible surrounding frames, this creates a flush solution with a clear, minimalist look.
With system solutions such as the MET 56, the invisible frame is plastered into the masonry during the construction phase. The actual door model – whether a solid interior door, loft door or all-glass door – can be chosen flexibly at a later stage.
This means that the decision on design and surface finish remains open even after the interior work has been completed.
Flush, frameless doors are in line with the current architectural trend towards clean lines, calm wall surfaces and maximum minimalism. They make rooms appear more sophisticated, modern and tidy, which is why they are particularly popular in upmarket residential construction.
