Extra stable doors

Product description

The extra-stable internal doors are very suitable for installation between rooms which have different climatic conditions, such as between an adjoining garage or back kitchen and the entrance hall. Where other internal doors have a warp behaviour of more than 8 mm, the extra-stable doors from Theuma have a maximum warp behaviour of just 4 mm (stability class in accordance with EN 12219).

The warping of internal doors is generally caused by differences in temperature and air humidity between the rooms they separate, in particular, rooms which are heated on one side of the door and are not (or are only slightly) heated on the other. This results in standard internal doors not closing, or only closing with diffi culty, as they become warped over time. With the new extra-stable door this negative effect is a thing of the past. Doors that close easily and well mean you suffer less from drafts and the cold.


The doors are available in square-edged designs. In climate class II c.


Theuma extra-stable internal doors are available in various models: white lacquered doors (EBC White Lion), primed doors and HPL-composite doors.

Range of application

Extra-stable doors are suitable for use in residential, commercial and industrial buildings. The doors easily satisfy legal requirements.

The perfect combination of door and frame

The doors are excellent in combination with our white-lacquered steel frames. These are finished with a highquality, scratch and impact resistant lacquer layer.

The door units can be delivered ready to install and provided with the necessary cut-outs, holes and the corresponding hinges and hardware. Then, no further processing is required on site. This means that these door units are by far the most economical solution in the construction and renovation process.
