Lift-slide door

Bring the spectacle to your house!

The lift-slide door is one of the most spectacular systems on the market, offering the possibility of very wide glass surfaces. The system is an innovative and functional solution for modern houses, offices and modern industrial complexes.
The rooms are flooded by light regardless of whether the door is closed or open, this providing extra elegance and comfort to the building.

This system redefines the barrier between interior and exterior space – the spaces merge while the benefits and efficiency of PVC joinery remain high. The depth of 190 mm and the ability of the system make it able to achieve a very low heat transfer coefficient (Uw) of up to 0.90 w / m2k.

Lift-sliding doors are available in two versions:

Classic, with symmetric view – in the standard version the visible side of the door (sash) is only 100 mm.


Design, with larger glass surface on the stationary part of the system – the entire visible surface (heel / sash) is reduced by more than 50%, while maintaining the thermal insulation characteristics unchanged.


The setup proposed by UNIKAT is near perfection! The cutting-edge hardware, innovative profiles and carefully chosen glass packages bring UNIKAT lift-slide system to the highest level.
