Zeroline function

The Zeroline function is suitable for virtually all areas of a construction project; it is the first concealed aluminium frame available on the market featuring a tested T30 fire protection function. The frame also meets requirements for smoke protection, acoustic insulation and break-in resistance as well as offering wet room suitability.

Zeroline living

In the Zeroline living version, the concealed aluminium frame is combined with a composite timber door leaf and does not meet any other functional requirements. This and an attractive price-performance ratio make Zeroline living particularly ideal for private domestic construction.

Zeroline glazing

On average, at least one door in every residential unit is a glass door. With Zeroline glazing, this is now also possible in combination with a frame integrated in the wall. Combined with a glass door, the frame not only makes for a modern design, but also improves natural lighting and transparency in the living space.
