Roto Patio Inowa | Turning your visions into reality

Roto Patio Inowa: the city is alive

Maximum variety

Different formats, frame materials and design variants offer a wide application range.

Maximum operating comfort

Easy to use thanks to innovative closing movement perpendicular to the frame profile and construction on roller bearings.

Can be extended with Soft functions which protect the entire sliding element from the sash slamming uncontrollably against the frame. They do so by mechanically braking the movement of the sash when opening and closing.

Tightly sealed

Permanently tightly sealed, even in extreme weather events with storms and heavy rain, thanks to circumferential gasket and active control of all locking points.

The tight sealing also offers perfect sound insulation, even with high levels of external noise.

Exclusive design

Harmonious appearance thanks to concealed technology and modern window handles.

Burglary protection

Reliably burglar inhibiting in accordance with resistance class RC 2 thanks to circumferential hardware with active locking points.

  • Anti-pushback function in the mullion prevents lateral movement and jemmying
  • Lockable handle with drilling protection
  • Can be extended with a wired contact element Roto E-Tec Control | MVS for opening and locking monitoring in accordance with VdS class B

Premium quality

Robust and well-made components, proven and tested many times over in accordance with the highest quality standards.

Roto Patio Inowa | Max

The version for very large sash formats up to 3000 mm wide and 3600 mm high 
and sash weights up to 400 kg

Sliding large and heavy sashes is effortless; a longer handle is not necessary.

This is possible in part thanks to newly developed components which, although they have the same function as in Roto Patio Inowa, are specially adapted for large and heavy sashes.

Ball-bearing-mounted roller unit

The roller unit contains robust, smooth-running rollers that effortlessly support the high weight.

The integrated linear ball bearing minimises rolling friction, so that even large and heavy sliding elements are easy to slide.

The integrated brushes keep dirt away from the rollers, therefore ensuring hassle-free operation.

Stabilisation unit

Depending on the size, one or two stabilisation units are installed as an additional locking point at bottom centre.

These do not support any load but help guide the sash and function as a locking point to ensure consistent gasket compression.

Comfort cam

The ball bearing comfort cams for timber, timber-aluminium and PVC profile materials replace the E cams in the centre locks and help with convenient operation of the sliding element.

Control cam

The ball bearing D13 control cams for the aluminium profile material replace the D8 control cams and help with convenient operation of the sliding element.

SoftStop function

The SoftStop function is used at sash weights above 200 kg. Inserted on the espagnolette or mullion side, it ensures gentle closing or opening of the sash by braking it.

At sash weights up to 200 kg, the SoftClose and SoftOpen Soft functions are used.
