Roto Patio Inowa – Outstanding sealing for sliding systems
Large sliding doors are increasingly popular as they bring more natural light inside and connect indoor and outdoor spaces. At the same time, excellent sealing performance is essential.

One of the key advantages of Roto Patio Inowa is that the sash is not only pressed against the frame but pulled tightly closed all around:
- even sealing on all sides

This results in excellent air and water tightness.
Large dimensions, easy operation
The system allows for:
- up to 3000 mm width
- up to 3600 mm height
- sash weights up to 400 kg
All while ensuring smooth and effortless operation.
Comfort and safety with Soft function
The optional Soft function:
- cushions opening and closing movements
- prevents uncontrolled slamming
- increases comfort and service life
Reliable in all weather conditions
The system ensures reliable sealing even under extreme weather conditions, including strong wind and heavy rain.
Modern, minimalist appearance
