→ Synchronous/Symmetrical Opening

Both doors open simultaneously. A large area becomes visible with
a single movement.

→ Weight Calculation and Material Selection

The weight of the door is important for selecting the correct fitting.
The gross density of the door material and its specific properties
must be factored in – for example, chipboard weighs less than MDF
because it is not as dense. If a mirror is attached to a door, the
weight of the mirror must be factored in during the calculation of
the door weight, as well as the weight of the fittings (straightening
fittings, handles, sliding door fittings).

Because of its higher density, MDF is much more stable than
chipboard and will not warp as easily. Extremely large and/or
thin doors and materials have a tendency to warp, therefore,
a straightening fitting must be used for alignment and stabilization
(e.g. Planofit). Doors that are already warped can also be straightened
with Planofit.

The following must always be taken into consideration when constructing
the door: The door must not be taller than 3 times its width.
Hmax = 3 x W
The weight of the door is calculated from the dimensions of the
door and the gross density of the material that has been used
Dimensional data not binding. Dimensions in mm, inches are approximate. We reserve the right to alter specifications without notice.
(see table below).
Weight in kg = H x W x D x density
To assist with the weight calculation, typical materials that are
used to make sliding doors have been calculated in kg per m 2
in the table.
