Tightly sealed: from the smallest to the largest aluminium sliding element

Leinfelden-Echterdingen – Thanks to its innovative closing movement perpendicular to the frame profile, the “Patio Inowa” sliding hardware ensures incredibly tight sealing, explains its manufacturer, Roto Frank Fenster- und Türtechnologie GmbH (Roto FTT). It is suitable for use in very small and very large windows and balcony doors up to a sash width of 3000 mm and sash height of 3600 mm. A version for sash weights up to 400 kg is now available. In September, the Roto Aluvision team will present a tested aluminium sliding system with “Patio Inowa” at the “Rivercruise” architecture trade fair. System suppliers and metal constructors can at any time obtain advice that is specifically tailored to them regarding the use of “Patio Inowa”. This service is also available online in the virtual “Roto City” on request.

Tightly sealed, even at great heights

Roto reports that the tight sealing guaranteed by “Patio Inowa” provides outstanding sound and thermal insulation at any height and in any climate zone. A sliding system equipped with this hardware offers draught-free living comfort, even in installation situations that are impacted by high wind loads, such as on the top floors of the high-rise residential buildings that are planned all over. Thanks to an extremely low threshold, “Patio Inowa” ensures an accessible transition in accordance with DIN 18040, which is a frequently requested feature.

Operating convenience for heavy elements
