The two drainage levels guarantee optimum protection agains wind, rain and noise

Schüco CT 70 AS door systems are suitable for a wide variety of uses in both new-build and renovation projects. An extensive range of accessories ensures a high level of system security.


Fabrication benefits

  • Easy-access threshold
  • Gaskets made of EPDM rubber are machine-rolled in the factory
  • Depending on structural requirements, different reinforcing profiles in the outer and vent frames ensure that the windows are highly robust and durable
  • Silver-grey gaskets on white profiles for discreet appearance
  • Special screw ports for fixing the corner pivot in the vent
  • Due to the 5 mm gasket clearance between the outer and vent frames, the vent rebate gasket does not need to be notched in the turn/tilt mechanism pivot area
  • Profiles can be coloured with a large selection of single colour and woodgrain decorative foils, Schüco AutomotiveFinish and Schüco TopAlu
