    Inotherm Cross-section of profile
    • Above-standard profile thicknesses
      Depending on the entrance door program you select, the thickness of the infill may be 54mm, 85mm and 105mm. Due to their above-standard thickness, all entrance doors provide you with outstanding thermal insulation and high energy savings.
    • Anti-bending expansion layer
      For better statics, an expansion layer is added to all entrance doors, which prevents the bending or deformation of the entrance door and maintains the stability of the door even with large temperature swings.
    • Triple Glazing
      All entrance doors feature glazing with three 6mm thick glass panes, which additionally insulate and enhance the safety of your home.
    • Additional seals
      Our doors are sealed with three round liquid seals with vulcanised corner joints for better thermal insulation.
    • Thermal bridge interruption
      A special heat barrier in the gap between the panel and the frame prevents heat from escaping and reduces your heating costs.
    • Aluminium threshold
      A robust aluminium threshold with a thermal break reduces the energy flow in the lower part of the door and allows for the invisible mounting of the door frame.
