Inowa Soundproof Sliding Doors

| Roto-Frank Inowa Series |

Keep the Elements Out and the Comfort In

The Inowa system (P130) builds on the robust German window & door styles to deliver class leading performance. It features tried and tested principles such as rectangular cavity design, double cavity corners, injection technology, and high-level resistance class (RC) designs. Roto Inowa systems also feature improved water tightness and wind resistance, and new dust proof technology for Asia-Pacific specific climatic conditions.

P130 Inowa sets a new standard when it comes to door tightness and is therefore ideal for buildings challenged by storm and torrential rain. The patented hardware system provides compression locking on 4-sides of the door, with easy operation with just one hand. The system guarantees to remain tightly sealed when facing challenges from extreme climate, especially in heavy storms. There is no trace of draughts or rattling sashes - thanks to the unique Roto technology. The Rotoi Patio 130 IW door system can satisfy the high performance requirements, in term of tightness, sound reduction and security. This makes it is perfectly suited for hotels, homes and commercial buildings.
