The sash can be fully reversed for easy, safe cleaning from the inside. The sash reversal takes place outside of the building to avoid damage to interior curtains or blinds.

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 cleaning of the opening is necessary. The sash and frame detail are the same for all window PN UNI variants, allowing styles to be fitted without changing profile routing. This ensures a uniform aesthetic appearance on all window styles.
