Building System Solutions

Sliding doors


  • a system featuring improved thermal performance, used to design sliding and lift-sliding structures
  • the UG sliding structures are intended for residential buildings, mainly private and public buildings
  • the system is adapted to the latest requirements relating to thermal performance, aesthetics and safety; available system options: UG low-threshold version, UG – 90° angular solution
  • with its parameters, the Ultraglide system makes it possible to design structures with vary large dimensions of sliding leaves; maximum structure dimensions available in the system: leaf height – Hs = 3300 mm; leaf width – Bs = 3200 mm.
  • the Ultrtaglide system makes it possible to design large – but still stable – sliding windows and doors; maximum leaf weight: 250 kg – sliding option; 400 kg – lift-sliding option
  • structure design: 3, 5 and 7 chamber frame
  • possible variants with two, three and four components based on the two-rail system
  • profiles suitable for installation of various hand-locked hardware available on the market and automatic devices
  • various types of infills can be used (double and triple glazed units)
  • system id adapted to the latest requirements relating to thermal performance; the system is equipped with a 22 mm/28 mm wide separator improved with glass fibre, thermal inserts and under-glass inserts to improve cross-sectional thermal performance; available options:UG, UGi and UGi+
  • used for designing large glazing, which provides natural lighting inside the building and facilitates interior design, with ensured stability, functionality and structure lightness;
  • there is possibility of use Flyscreen system (Flyscreen - fly screen are a practical and an extremely funcional protection against insects)
  • a wide range of colours available - RAL palette (Qualicoat 1518), structural colours, Aliplast Wood Colour Effect (Qualideco PL-0001), anoda (Qualanod 1808), bi-colour
