Lift and slide door (HST) give the possibility to let the sunshine in to your home! With a smooth-running lifting mechanism even huge sliding elements can be moved very easily even with maximum size of construction 6.0 m x 2.80 m. Another advantage is the space saving design.

HST is available in three different versions:

  • the basic version that meets all the requirements of the latest German Energy Savings Regulation
  • the standard version with extra thermal insulation
  • the premium version with excellent, passive-house suitable thermal insulation values.
