For particularly large terrace doors the lift and sliding doors are the design to choose as these can be opened easily and most conveniently.
Lift and sliding doors have no tilt function – the window elements are opened via rails recessed into the floor to allow a barrier-free transition. Very little force needs to be applied to push the movable sash elements into the horizontal position.
Apart from a high resistance to wind and watertightness Deceuninck lift and sliding doors set standards with regard to thermal insulation boasting a Uf-value of 1.3 W/m²K. They also guarantee high stability based on a continuous steel reinforcement in the frame and sash.
