Lift and slide patio door is best for locations as balckonies, terraces and other places where there is not enough room for traditional outward or inward opening solutions, or where is a need for large glazed areas.

Viking Window sliding patio doors are equipped with high quality and modern GU-934-H hinges system which has load bearing capability 300 kg. Active leafi is located on inner side of door ensuring functionality for winter times - ice and snow does not damage rails. The espagnolette and strong handle enable convenient operating and possibility to close door in ventilation position.

Sliding patio door is available both as wooden and aluminium clad door. Traditional double glazing (Ug = 1,1 W/m2K) or energy efficient triple glazing (aluclad door 52 mm glazing unit  Ug = 0.52 W/m2K; timber door 40 mm glazing unit Ug = 0.64 W/m2K) can be used.

Finishing according RAL, NCS (paint) or Vikings (lacquer) tone catalog by customer's choice preference.
