Winkhaus and Kawneer: Partnership and Collaboration Behind the Launch of Kawneer’s Ground-Breaking KWD92 UT+ Window System

Market leading manufacturer of door locking systems and window fitting systems, Winkhaus UK, was proud to attend the launch events of the new KWD92 UT+ Passive House window by Kawneer, a leading provider of architectural aluminium products, following an 18-month development program.

The KWD92 UT+ is designed with the fabricator in mind offering key fabrication benefits. The Winkhaus efficient window system hardware, aluPilot together with Kawneer’s pre-set gasket and corner assembly which potentially offers 30% faster fabrication time.

KWD92 UT+ Window System

Passive House certified, the KWD92 UT+ features a multi-chamber thermal break core and Kawneer's patented reflex technology. This combination delivers market-leading thermal performance, achieving values as low as 0.6 W/m2K without requiring additional foam inserts in the thermal chambers.

Passive House is a leading energy-efficient building standard that ensures indoor comfort and insulation through exceptional airtightness and thermal performance, resulting in minimal energy usage and clean air. It promotes the construction of healthy, comfortable, and sustainable buildings.

Time plays a vital role in the installation of windows, and the new KWD92 UT+ window system allows fabrication to be up to 30% faster than Kawneer’s current range. Using Winkhaus’ efficient fitting system, aluPilot, aluminium fabricators can manufacture the windows at least 10 minutes faster per window compared to traditional aluminium Euro Groove systems. Faster and easier installation can reduce the cost price of an aluminium window, saving time, money and increasing productivity.

Maria Morgan, UK Product Manager for Kawneer comments "We are delighted with our collaboration with Winkhaus to help introduce our new innovative Passive House window to the UK market. This partnership combines our expertise in sustainable building solutions with Winkhaus’ own commitment to providing efficient sustainable solutions, that together help set a new standard for performance, speed, and efficiency. Together, we aim to provide homeowners and builders with a high-performance Passive House window that not only meet but exceed the requirements of the Passive House standard, ensuring superior thermal comfort and energy savings."

aluPilot: Click. Click. Done

aluPilot’s time-saving result has been confirmed through extensive testing with manufacturers during the development and roll-out of aluPilot to European and UK systems houses. When multiplied across weekly production, these time savings really start to add up. The drive rod concept of aluPilot simplifies and streamlines the window manufacturing process by eliminating several traditional steps:

• No cutting or punching of connecting rods
• No punching of profile grooves
• No waste from offcuts of connecting rods
• No Screws


With aluPilot, components are clicked into place, making the process more efficient and reducing cutting waste. This innovative system offers a comprehensive range of mounting accessories for easy installation.

Simplified Manufacturing - The streamlined manufacturing process eliminates the need for cutting or punching connecting rods, profile groove punching, and screws. Components click into place, reducing waste.

Easy Installation - Installation is made easy with an external bayonet locking system for secure power transmission, a CLICK mechanism for seamless sash hinge fixing, accessible height adjustment, and tool-free sash installation.

Smart Packaging - Organised and protected components are provided in one box, minimising the risk of missing parts and reducing hardware by up to 70% in burglar-resistant setups.

Complete Tool Concept - aluPilot includes essential installation accessories: a Drive Mounting Tool for securing the drive, a Positioning Aid for precise keep placement, Sash Edge Protectors for corner protection, a Drilling Jig for PAS24 screw positioning, and a specialised Jig for Security Locking Modules. These tools streamline fabrication, ensuring efficient and accurate window assembly.

Testing and Development

When integrating the aluPilot system, the components underwent rigorous testing in conjunction with KWD92 UT+. This included weather testing such as air permeability to EN 12207 (Class 4), watertightness to EN 12208 (Class 9A) and resistance to wind to EN 12210 (Class C5), as well as security testing to EN 1627 RC2 and PAS 24.

This testing phase provides seamless compatibility and functionality, ensuring that aluPilot becomes an integral part of the profile design. By testing the "click in" system components alongside the profiles from the systems house, any necessary adjustments or fine-tuning can be made at Winkhaus to optimise performance and reliability, meeting the precise requirements of the system.

This collaborative testing process not only enhances the integration process but also ensures that the final product meets high standards of quality and performance.

With over 100 years of combined industry expertise in product development, manufacturing, and testing, the Winkhaus technical and laboratory teams offer proven solutions to ensure the success of its partners’ future innovations.

Our added value services include consultation, CAD design, 3D prototyping, product assessment, product development days, and UKAS laboratory accreditation.
