One system – Four variants: Roto Patio Alversa: Minimal. Universal.
One Tilt&Slide and three Parallel Sliding solutions including different ventilation functions for sash weights of 160 to 200 kg in all frame materials– That’s what the universal hardware Roto Patio Alversa offers.
The special feature of the system: parallel sliding and tilt ventilation are combined. The advantage for production: the modular system design means window manufacturers can produce all four variants on one and the same production line. Patio Alversa enables designs with a sash rebate width of up to 2,000 mm and a sash rebate height of up to 2,700 mm. The hardware is also suitable for larger profile depths, if, for example, triple glazing is required.
Simply open and close
The sash elements of the three Parallel Sliding solutions are operated in the same way as Tilt&Turn windows: the sequence is intuitive and therefore extremely user-friendly. The 200 mm long handle lever is always operated in the same sequence.
Quadruple fresh air
In the Tilt&Slide version Roto Patio Alversa | KS, air exchange is achieved via the tilt ventilation position of the sash. The three Parallel Sliding versions allow you to choose between night ventilation on the Patio Alversa | PS and tilt ventilation on the two Patio Alversa | PS Air and Patio Alversa | PS Air Com versions. The night ventilation on the Parallel Sliding version Patio Alversa | PS is not visible from outside,and instead the parallel retracted sash looks as if it is locked. The Parallel Sliding version Roto Alversa | PS Air Com offers particular operating convenience: turning the handle tilts the sash automatically – without manual pressure against the sash.
No matter how stormy the weather…
With multiple glazing in particular, the centre of gravity of the Tilt&Slide sash is outside. Nevertheless, thanks to the optional additional lock-in position, a Patio Alversa sash does not blow shut even when the wind load is high.
The additional lock-in position is integrated in the sliding scissor stay of the two Alversa | PS Air and Alversa | PS Air Com tilting variants.
No ifs or buts
The ball bearing roller units of high-quality, low-wearing PVC ensure quiet movement of the sliding sash with maximum system protection in all four versions. Its run-in and runout characteristics are additionally optimised by special damping elements. Anti-lifting protection is integrated in all roller units. The anti-lifting device does not have to be activated manually after installation.
Ultimate efficiency
Its intelligent design makes the Patio Alversa product range a real cost-saver. The universal central locking system stems from the Tilt&Turn systems Roto NX or Roto AL. Bogies, sliding scissor stays and track sets can be used for several versions. In addition, four identical corner drives are used for central espagnolettes. This means greater standardization and fewer parts, which significantly reduces storage and logistics costs.
Fewer parts, faster processing
The prominent use of identical parts across all four versions enables quick processing in the line without having to spend a lot of time converting the production plant after each order. Administration and, above all, the master data processes are also significantly reduced. Replacement of the hardware version does not require any or only minor conversions in production, as only individual components have to be replaced.
Reliably secure
All four Alversa variants provide resistance in accordance with RC 2, especially through the use of four components that fabricators arealready familiar with from the Tilt&Turn hardware portfolio: security mushroom locking cams installed around the frame, robust security strikers with multiple screw connections, lockable handle and invisible drilling protection installed in the groove. The security mushroom locking cams are adjustable in terms of height and gasket compression.
Where there are increased requirements for security, electronic components from the Roto E-Tec Control range can additionally be used. The sensors of the magnetic locking and opening monitoring system are integrated into the striker. Like all other security components, they remain invisible.
Ready for Smart Home
Roto Patio Alversa can be digitally extended by including Roto Com-Tec. Its sensors detect any manipulation of the sliding element and can also warn homeowners via Push message depending on the Smart Home system used. The Roto Com-Tec sensors Comfort and Comfort S identify the position of the sliding sash and indicate whether it is securely locked. The durable, reliable function of the sensors is supported by their concealed and therefore low-wearing position on the corner drive.
User feedback “We have supplied more than 300 aluminium sliding doors with Roto Patio Alversa | PS for the Donna Tower project in Dubai Silicon Oasis. Our employees find the elements easy to produce and install. At the same time, the customer is very satisfied with the systems, because they provide high operating convenience for the residents. Did Roto providegood and reasonable support at the start of production? I would score them 10 out of 10. The service and advice were faultless and made it easy for us to get started. The two Donna Towers are being constructed as mixed use real estate by Aakar Developers and offer studios and apartments on 35 floors. With their extensive service installations, large panoramic windows and Italian interior design, they are attractive to tenants from across the globe. We are convinced of this.”
User feedback “Sliding doors and windows are becoming increasingly popular as a space-saving solution. At Avante, we have been fabricating the Roto Patio Alversa modular hardware product range since 2019 in PVC window production for Parallel Sliding and Tilt&Slide systems. Our retail partners very successfully sell sliding systems with the three hardware versions Alversa | KS, Alversa | PS and Alversa | PS Air Com. For our production, it is of course an advantage that many of the components can be used in all three versions. This reduces the number of components to be kept in storage. Employees in the factory have been able to establish a great routine. And the assemblies are so well coordinated with each other that there is little waste. That’s also becoming increasingly important: reducing waste, handling expensive raw materials efficiently and recycling what little it left over. We agree with Roto about that.”
User feedback “Since Prestige Ablak was founded in 2012, we have been fabricating hardware from Roto and are impressed by the Patio Alversa range. We were one of the first Hungarian manufacturers to introduce this range and we have been using it for several years now. We have already ensured high levels of satisfaction among many of our customers with the Alversa | KS and Alversa | PS Air Com versions. In particular, our customers are impressed by the easy operation via the handle and the simple tilting with the PS Air Com. As we have been selling Parallel Sliding and Tilt&Slide elements for both versions for many years, we know that there are practically no complaints. And if ever a customer does experience damage, the spare parts are very easy to procure from Roto. Since we also work with the Roto NX Tilt&Turn range, we only need a few additional parts for a sliding door. That helps us to produce economically.”
