Modern system of sliding door and overhead sliding door with thermal insulation.

The system is offered in 2 versions of the built in depth: DP 86 and DP 110. Excellent thermal insulation was obtained using thermal separators precisely in the plane of the glazing and thanks to dividing the structure zones to: warm (with thermal insulation) and cold (without insulation). It is the only solution of this kind available on the market.


  • fast and simple prefabrication thanks to frame profile cutting at 90º angle,
  • simple and fast assembling and disassembling of door sash due to sash profile cutting at 45º angle and connecting by the use of twisted connector,
  • possibility of glazing by the use of clip accelerating glazing process and ensuring simple replacement of glass pane in case of crack,
  • patented solution of drainage element simplifying construction of drainage system simultaneously enhancing its efectivity,
  • the only system of this class available on the market which enables manufacture of overhead sliding structures,
  • solution of the so called “narrow mullion” in DP 100 version,
  • possibility of connection DP SLIDE constructions with side transom,
  • 50 mm widening simplifying roller shutter box assembling,
  • profiles allowing for the so called “French” assembly, which involves installation of the structure on an old frame covered with aluminium angle profiles.
