New thresholds for “Roto Patio Inowa” and “Roto Patio Inowa | Max”
“Comfort” and “Flex”: a new approach to accessibility, sealing and installation / “Comfort”: barrier-free in accordance with DIN 18040 / “Flex”: masterful flexibility / Efficient for window manufacturers to work with / “Inowa” and “Inowa | Max”: tight sealing, convenient sliding technology, large formats, security and a slim design
Leinfelden-Echterdingen – Roto Window and Door Technology is adding two newly developed solutions to its “Inowa” and “Inowa | Max” parallel retraction sliding hardware systems in the form of the “Comfort” and “Flex” thresholds. Both of these new additions can be used on timber and timber-aluminium elements. Window manufacturers benefit from a fully integrated systematic approach where the hardware, threshold and seal are optimally coordinated. The result? Tight sealing, convenient operation and simple incorporation into existing production processes. All the relevant information can be found on the Roto website at ftt.roto-frank.com/en/inowa and in the brochure “Turning your vision into reality”, available at ftt.roto-frank.com/en/bro-346.

“Comfort” threshold: barrier-free in accordance with DIN 18040
The “Comfort” threshold is designed with barrier-free construction in mind and meets the requirements of DIN 18040. The threshold is recessed into the floor on both sides, creating an almost completely level transition which is very easy to roll over according to ift guideline BA‑01/1, class 5. Thermal separation in accordance with DIN 4108 and a circumferential sealing level ensure energy efficiency and reliable protection against the weather. As a result, the “Comfort” version is suitablefor public buildings as well as for residential properties where the priority is accessibility and comfort. The “Comfort” threshold – which is available now – can be used on inward running sashes of both “Inowa” and “Inowa | Max” hardware versions.
“Flex” threshold: masterful flexibility for new builds and renovations
Roto offers the “Flex” threshold – which is also thermally broken – for flexible applications. It is used on outward running sashes of the “Inowa” and “Inowa | Max” hardware versions, both in new builds and in renovations. The threshold can either be recessed into the floor on one side or completely surface-mounted and allows for a 22 mm height offset including roller track. If it is recessed, an assembly height of as low as 4 mm can be achieved in the room. The “Flex” model will be available at the end of 2026.
Efficient for window manufacturers to work with
Both thresholds are compatible with various profile systems and are deliberately designed to be efficient to work with. Sophisticated hardware sets allow many of the same parts to be used. Straight cuts on the profiles, smart snap-in and clip connections plus minimised use of screws and liquid sealant result in quicker installation and reduced service requirements. The thresholds are compatible with proven components from the “Roto NX” Tilt&Turn hardware system, which also makes them simpler for window manufacturers to incorporate into their existing production processes.
Tight sealing and convenient sliding technology
“Inowa” and “Inowa | Max” are characterised by the innovative closing movement perpendicular to the frame profile combined with circumferential, actively controlled locking points. This principle clearly sets them apart from traditional Lift&Slide doors and provides far better sealing – including in the mullion. The smart system reliably protects against draughts, rain and external noise in extreme weather conditions and in multi-storey buildings. The structure is entirely mounted on rollers for effortless, quiet sliding even at leaf weights of up to 400 kg. The “roller unit Plus” and retaining devices achieve ultimate stability for the sliding door even with high wind loads. The Soft functions offer extra comfort. They gently brake the leaf before the final position is reached when opening and closing.
Large formats, security and a slim design
Both versions of the hardware system offer the perfect match fortimber and timber-aluminium and sliding elements with complex architecture: Concealed hardware components and delicate strikers makeit possible to create slim profiles and a modern, minimalist appearance.
“Inowa” is designed for sash weights of up to 250 kg, while “Inowa | Max” can be used for sash weights of up to 400 kg. This makes the hardware suitable for sliding elements, from small to large, and ensures maximum operating convenience for sash heights of up to 3600 mm, sash widths of up to 3000 mm and also in 3:1 format. What’s more, a low, very long sliding window system can be produced up to a frame width of 4000 mm, for example, using “Inowa | Max”.
All elements can be manufactured in accordance with resistance class RC 2. For opening and locking monitoring, concealed, wired contact elements from the “Roto E-Tec Control | MVS” system in accordance with VdS class B can be added to both versions of the hardware.
