PrimePort to be unveiled at FIT

Winkhaus UK will be presenting the new PrimePort system family for the first time at FIT Show 2025.

PrimePort is a versatile fitting system for sliding and balcony doors and windows, covering tilt and slide, retract-slide or lift and slide applications. It is said to offer unrivalled ease of fabrication and use, adapting perfectly to aluminium, timber, or PVC-U.

Winkhaus has developed the new PrimePort AS retract-slide fitting especially for installation situations in urban environments. This fitting allows generous window openings without the open sash taking up space in the room. The PrimePort AS’s unique retract-slide mechanism keeps the window tightly closed, even when high wind loads act on the facade. This also makes it suitable for use in sliding doors and windows in high-rise and multi-occupancy buildings.

All moving fitting parts are concealed in the window frame – no additional cover profiles are required for the Winkhaus technology – which gives PrimePort AS doors and windows an elegant appearance.

PrimePort AS is suitable for a wide range of sliding door and window formats and weights: The standard version carries up to 200kg, and with tandem bogies the maximum sash weight is increased to 250kg. Like all Winkhaus systems, PrimePort AS is also designed to be user-friendly. The central locking system can be configured from the ActivPilot modular system, supplemented by a few additional elements. Thanks to the roller-guided closing mechanism, the window can be operated with little effort. The low number of coupling points simplifies installation.

PrimePort AS can optimise the functionality and security of the sliding element with an additional comfort component. The ‘softclose’ function ensures a convenient pull-in for the retract-slide fitting. This ensures that the sash closes smoothly to the desired position. Thanks to the individual arrangement of the frame part, the softclose feature can also be converted into a safety stop function.

This includes braking the sash in the desired position which can prevent injuries such as trapping limbs.
