Folding Doors

Folding doors are ideal for locations where there is a need for large opening areas: opened door leaves are fixed on the side(s) of the product. This way the opening is completely clear.

This product is based on same profile system as the Norrsken inward opening timber window (therefore it does not have a conventional threshold). In addition to the traditional sideways slide opening, it also tilts at the top for ventilation. ROTO hinge systems enable us to manufacture an opening sash of up to 130 kg. The profiles and technical properties are similar to the Norrsken DK10 window.

Our folding door is available in timber and aluminium clad. Traditional double glazing (Ug = 1,1 W/m²K) or energy efficient triple glazing (Ug = 0,6 W/m²K) can be used.

Finishing according to RAL, NCS (paint) or Norrsken’s (lacquer) tone catalogue by customer's choice preference.
