Doors are classified by intended use, number of door leaves and material of door leaf. Viking Window supplies a factory assembled door set: leaf, frame, threshold, hardware
- Front doors - typically with handle and key locking cylinder (as an alternative on the interior side a turn knob is used); use and size of glazing varies - glass provides view to outside or is used only as a design element.
- Terrace doors- (balcony doors) typically with more simple window-type hardware (e.g. window handle, espagnolette with similar functions as windows etc.). Sometimes handle is used only on the inside. Cylinders for locking can be used - if the handle is on both sides. Mostly with the max size glasing unit to maximaze the light gain.
- Sliding doors - opening function is sideways sliding. May be also combined with upwards, outwards, inwards or tilt function - depending on the hardware used.

Profile door leaf is assembled of glue-lam timber profiles. In the openings of the leaf either glass or insulated panels can be used.
