Sliding walls


Optimal 110 EI15/EI30

Sliding walls with fire resistance EI30

The Optimal 110 EI15/30 mobile acoustic wall system provides fire safety of people who are in the building, the confirmation of which are research results from the Fire Testing Department ITB. The system is also available in automated version.



Parked wall

Possibility to mount modules at any location also in the cavity.


Wall folding

Modules are sliding manually, one after another.


Complete wall

Due to module strutting, acoustic and physical barrier is created.

The wall divides premises, allowing their arrangement in accordance with current needs.



The door constitutes a convenient way of communication between divided premises.

System structure

Optimal 110 EI15/30 walls consist of flame-resistant modules that are 80 cm – 130 cm wide and the height of which corresponds to the conditions of the premises. The wall is 11 cm thick.


Modules are suspended in the aluminum runway that is mounted in the ceiling surface.


Optimal systems do not require any cumbersome floor guides.

We design all methods of wall parking from simplest to most complex – depending on the room conditions.


Another advantage of our system is the possibility of placing on the bottom section of the wall, single- or two-winged key-closed door.


The door are the integral part of the wall in terms of visual and operational.


Sound insulation of Optimal 110 EI15/EI30 system is Rw = 48 dB.


Optimal 110 EI15/EI30 system is availablein automatic version.


Operation of automatic wall consists in manual setting of modules in the wall axle just as in manual version.


At the time of contact of two modules, the electrical engine is started that pulls out module stabilizing strips.

Optimal 110 EI15/EI30 has undergone the complete set of tests at the Building Technique Institute in Warsaw.


Our sliding walls have been tested for:

– safety of use

– load resistance

– correct operation

– sound insulation

response to fire B-s1, d0

fire resistance EI30


All the tests were positive within the upper tolerances for the product.
