Sliding Doors Take the Lead and Winkhaus Has the Fitting System to Match.

primePort: Three High-Performance Solutions for Today’s Top Trending Style

As reported in the Spring Edition of the Keystone Market Research – UK Consumer Fenestration Trends Report, homeowner demand is shifting decisively:

Sliding Patio Doors Now Firmly Lead: Sliding windows and doors have quickly become the patio door style of choice, overtaking bifold doors by an increasing margin. This preference was consistent across all 12 UK regions, establishing sliding doors as a key offering for all installers.

This market trend puts sliding systems at the heart of the modern fenestration offer, helping fabricators and installers looking to respond quickly and confidently, Winkhaus primePort delivers a complete family of solutions combining precision engineering with intuitive usability and long-term performance.

Whether the project is a compact apartment, a luxury self-build, or a multi-storey development, primePort offers a tailored fitting system for every style and structure:

• primePort SK: Tilt-and-Slide & Parallel-Action Slide
• primePort AS: Retract-Slide
• primePort HS: Lift-and-Slide

All three are designed for use across timber, aluminium, and PVC-U systems, and offer dependable operation, weather resistance, and smooth mechanics. Most importantly, they are designed to comply with PAS24, supporting secure door and window specifications for the UK market.

primePort SK: Flexible, Functional Tilt-and-Slide

Available in SK-S, SK-Z, and PAS variants, the primePort SK range offers fabricators a smart, scalable tilt-and-slide solution ideal for domestic windows and patio doors.

The flagship primePort SK-Z version enables large window sashes up to 220kg to tilt with just a 180° turn of the handle to automatically move the sash into a safe and secure ventilation position, reducing the risk of operating errors while enhancing day-to-day convenience.

Additional features include:

• Intuitive smooth operation using proven activPilot technology
• Simplified adjustment with TX25 tool access
• Tool free sash attachment for efficient production
• Optional damper equipped bogies
• Large opening width up to 135mm, suitable for deep profiles
• Colour-matched caps and cover profiles in seven modern finishes

The primePort PAS version also enables gentle parallel-action ventilation (approx. 6mm opening), combining airflow, occupant safety, and security, ideal for homes with children or pets.

For fabricators, the use of existing activPilot parts and compatibility with standard turn-tilt profiles mean faster production, lower inventory, and seamless integration into your fabrication line, especially with profiles already available from six of Europe’s leading PVC-U profile manufacturers.

primePort AS: Retract-Slide for Urban Versatility

Developed for use in modern buildings where space-saving and performance go together, primePort AS is the answer for compact interiors, high-rise living, and commercial properties.

Its standout feature is the retract-slide mechanism, keeping the sash flush to the frame when open, delivering maximum opening width without compromising internal space. A perfect choice for sliding balcony doors or window solutions in tight city layouts.

Key advantages include:

• Sash weights up to 250kg
• Exceptional wind load resistance and weather performance
• activPilot central locking system for reliable sealing and security
• Minimal visible hardware thanks to fully concealed components
• Optional Soft Close and Safety Stop for comfort and safety

For specifiers working in public buildings, multi-occupancy
apartments or exposed elevations, primePort AS combines aesthetics with proven performance, and gives fabricators the confidence to quote competitively with a high end, low effort product.

primePort HS: Lift-and-Slide Without Limits

For the ultimate in large opening door solutions, primePort HS offers a premium lift-and-slide system capable of handling sash weights up to 440kg with ease. Ideal for luxury residential applications, extensions with panoramic views, or anywhere large format glazing is in demand.

Its ergonomic handle and smooth lift-glide action ensure ease of use even with the heaviest panes, and the low threshold option provides accessibility for all, in compliance with inclusive design standards.
Performance benefits include:

• Soft, low-force operation across large opening spans
• Available with hook or bolt locking drive
• Engineered to meet the requirements of PAS24
• Robust construction for long-term reliability and weather resistance

And, like all systems in the primePort range, a consistent design language across handles, caps, and finish options helps unify your project portfolio and support a premium aesthetic.

Modular, Compatible, and Efficient

Beyond their mechanical performance, primePort systems are designed with fabricator efficiency at their core:

• Cross-system compatibility across aluminium, timber, and PVC-U profiles
• Shared component design across SK, AS and HS variants
• Simple toolkits and fewer unique parts to streamline production
• A choice of seven modern hardware colours, including anthracite, titanium, and deep black

That means fewer stocking challenges, faster assembly, and greater flexibility in production schedules.

And with activPilot as the backbone of the locking technology, primePort benefits from proven security and functionality trusted across the Winkhaus portfolio.
