Details on barrier-free use
The Urban M1³ barrier-free was developed to break down barriers in everyday office life without the box seeming like a “special solution”. It fits seamlessly into the modern design of the Urban Line.
Barrier-free access & operation
- Ground level access: No base, no steps – the wheelchair enters the cabin directly at floor level.
- Electric door opening (button): The door does not have to be opened manually. Simply pressing the button on the outside opens the door automatically.
- Access control options: Can optionally be combined with password or face scanning systems for protected work areas.
Transparency to DIN 18040
In order to give you maximum planning security, we are transparent about the dimensions:
- Door lights: approx. 82cm (The M1³ is therefore wheelchair accessible. For the full DIN standard of 90 cm, please select the L2³ barrier-free).
- Interior: Due to the design, the turning area is just under the required 150 cm, but is optimized for standard wheelchairs.
Soundproofing & Acoustics
Sound insulation (measured according to the latest ISO 23351-1 standard):
-
Plus: 32±3 dB (ISO Class A)
- Maximum discretion for concentrated work and phone calls.
(Important: The switchable “Smart Glass” option automatically includes the best possible plus sound insulation).
💡 Good to know: How to read our acoustic values
- Certified standards: Tested according to ISO 23351-1.
- The masking effect: The office “swallows” the remaining noise – the work in the box remains inaudible to colleagues outside.
