Stacking door SPACELITE HTvision

When an industrial door turns into a moving glass curtain wall

Very often in modern, representative buildings, industrial doors form an architectural foreign body. With real glass and the design of a glazed curtain wall the new stacking door SPACELITE HTvision can contribute to a sophisticated solution both in design and in technology. The function as an industrial door with a beneficial opening technology and well-known Butzbach quality remain core features of this door.



Function and design brought to perfection:

  • Curtain wall design without vertical inter-spacer up to 3.96 m door width (with inter-spacer up to 5.0 m width)
  • Insulation glass with twin-walled toughened safety glass with excellent thermal insulation values for sustainable building: Ug =1.1 W/m2K
  • Advantages compared to acrylic glass: No scratches and cleaning traces, no fogging, condensation or dirt between the panes, no optical deformation of the panes
  • The combination with door panels made of light transmitting fibreglass is easily possible

Opening technology with reduced space requirements:

  • Upon opening the door panels stack safely and compactly behind the lintel where they are protected
  • Due to the wall attachment, the minimum space requirements and the easy adaptation to individual needs the door suits nearly every installation situation, also for renovations
  • Meets the requirements of German regulations concering overhead-glazing

Reduced cost for operation and maintenance:

  • Electric drive with an extremely resistant and enduring gear motor
  • Direct drive without any additional parts which are prone to wear and tear such as torsion springs, hinges, spiral cables and end position dampeners
  • Micro processor control for trouble-free operation and comfortable controlling

Sustainability and safety:

  • Effective door seals for improved energy consumption by avoiding air exchange
  • Anti-drop protection: falling door panels are stopped immediately (tested and approved)
  • Superior user safety due to a safety edge: in case of contact the door automatically stops and re-opens
  • Door tested and approved according to DIN EN 12241-1
