Fixed walls


Optimal Office EI15/EI30


System of beamless, aluminum-glass fixed walls Optimal Office EI15/30 provides fire safety of persons in the building. Thin aluminum profiles allow to use plenty of glass in the wall view.


Optimal Office EI15/30 is a minimalist system of glass walls of fire resistance. Thin system design – width of profiles is similar to the glass width – it is an aesthetic revolution in the market of current massive fire systems.

System structure

System Optimal Office EI15/EI30 is composed of aluminum profiles connected with fire-proof material and glass filling of proper fire resistance.


Base profile with a rectangular section is installed directly into the ground, walls or the ceiling. Glass strips are fixed to the base profile. We use 17 mm glasses in walls EI15.


EI30 walls are fitted with 17 mm or 30 mm glasses. In walls of up to 3 meters we use Vision Line 17 mm glass panels, which thanks to the layered designed have no black bonding frame. For higher sound requirements or walls higher than 3 meters, we use 30 mm glass panels.
