Roto is aiming to offer greater benefits for customers and users of “Roto Patio Inowa” by updating its product series with new functions for more operating convenience and safety, further simplified installation and reduced complexity. The demand for the “smart hardware for tightly sealed sliding systems” had been rising continuously, according to the company.
The reason for this increased demand is the hardware’s characteristic features, say company officials: the special closing movement of the sash transverse to the frame profile, the surrounding gasket and the active locking points in the mullion, which can be activated by lever handle. This is supplemented by the variety of possible applications, from small kitchen windows to floor-to-ceiling elements.
New Features
A new product configuration is the “SoftClose” function. This brakes the sliding sash and causes it to close automatically. This function makes the sash much safer and more comfortable to use, which virtually eliminates the risk of misuse or incorrect operation. This function is fulfilled by a steel gas spring which becomes tensioned when the sash is opened, while storing force for closing the sash again later.
As Roto states, the counterpart to this is the “SoftOpen” function. It briefly brakes the sash after opening and then moves it to the end position. The gas spring plays a crucial role here too.
Both versions can be combined and can be installed together in the hardware system up to a sash weight of 440 lbs. This applies to all frame materials―PVC, timber, timber/aluminum and aluminum. Mechanically controlled, braked opening and closing ensures lasting fault-free operation of the sash and prevents uncontrolled collisions with the frame.
Roto also offers an alternative for sashes weighing more than 440 lbs. The “SoftStop” function also caters to the general trend towards higher element weights.
A specially developed tensioning tool is used to activate each function. It can be used as early as during production of the sliding window or after installation in the building. The components, with the control unit which comes integrated into each version, are effortless to install, say officials. The minimal complexity thanks to the low number of items allows for cost-saving production in all frame materials. The three “Soft” functions are always installed concealed at the top of the sash. No routing work is required on PVC and aluminum elements. The profile used determines whether any routing needs to be carried out on timber sliding systems.
Installation
There is “good news” for installation process, as well. First of all, the number of screws has been reduced from six to four, per assembly, which speeds up installation of the control unit, center closer and roller unit. The three optimized components fit into the same profile installation space as the current range. Manufacturers of sliding elements will also still benefit from the high level of tolerance compensation that is typical of this hardware series.
Last but not least, the time-intensive manual step of operating the handle lever several times to undo the center fixing is no longer necessary. All that is required now is simply to screw the components together.
