  1. Location in the building:
    o External windows – a “warm” filling, thermally insulated profiles
    o Internal windows – a “cold” filling, thermally insulated profiles
  2. Thermal requirements:
    o No requirements
    o Standard requirements
    o Requirements for passive buildings
  3. Way of opening:
    o Fixed
    o Awning – casement open inward
    o Casement – awning open inward
    o Casement open outward
    o Top-hung casement open inward
    o Awning open outward
    o Slide
    o Lift
    o Lift-slide
