Leinfelden-Echterdingen – Renowned manufacturers use the “Roto AL Designo” concealed hardware to produce design-led yet robust aluminium windows. Roto Fenster- und Türtechnologie, global market leader in Tilt&Turn hardware, developed the “AL Designo STS” hardware specifically for flush profile systems with the V.01 frame groove. Demand for this product has grown constantly since it was launched last year. This is why the construction supplier is now extending the range with the addition of Turn-Only hardware which can be used to produce extremely slim opening elements from a width of 250 mm as well as very small ones from a height of 520 mm without any tilt depth restrictors.
Economical production of small or slim elements
The new Turn-Only hardware makes production both simple and efficient for manufacturers: when mounting the sash stay and pivot rest, the fitter firstly drives in mounting wedges and then only needs to insert a single retaining screw. At the same time, since just a few components are required, the Turn-Only hardware is extremely economical to work with. The installation video is available at ftt.roto-frank.com/en/iv-al-designo-sts/.
Complete comfort, even with little clearance
The kinematics of “AL Designo STS”, which are optimised for flush profile systems, prevent collisions when opening a window sash or a ventilation flap up to a 100° angle, even with little clearance. Damping elements reduce the noise level when operating the element.
Best protection against corrosion
The punched parts of all components in the “AL Designo STS” range are made from stainless steel and meet the requirements of corrosion class 5 in accordance with DIN EN 1670. This means that they are the right choice, even when hardware and windows are exposed to extreme weather conditions and exceptional loads. The new Turn-Only hardware has also been successfully certified in accordance with J/GT 125 and DIN EN 13126 part 8 class H3.
Variety of locking versions and opening restrictors
The new hinge side is compatible with many components from the “Roto AL” modular hardware system and various opening restrictors from Roto. Since it is already on show in the virtual “Roto City”, anyone who is interested in it can find out all the technical details there with their specialist advisor at a time that suits them and design hardware solutions tailored to their individual needs. The technical documentation (IMO 575) relating to the extended “AL Designo STS” hardware product range is now available at media.ftt.roto-frank.com in the download centre on the Roto website.
Users of the “AL Designo” concealed Tilt&Turn hardware only need a few additional components to flexibly work with different types of aluminium profiles using “AL Designo STS”, benefiting from efficient logistics as a result. “AL Designo” and “AL Designo ST” remain concealed, even in very slim profiles.
