The built in adjustable friction gives high durability and stability to the window. This variant is supplied with a bottom rail suitable for timber, plastic and aluminium profiles.

The robust system has been designed with multi-storey public and commercial buildings in mind, including hotels. Equally suitable for high-rise domestic applications, the hardware solution is ideal for situations in which safe control of the opening is necessary.

The projecting side hung is capable of achieving emergency escape (providing that all relevant building regulations are met).

The sash and frame detail are the same for all window ROTO FRH UNI variants, allowing styles to be fitted without changing profile routing. This ensures a uniform aesthetic appearance on all window styles.
