Turn Fitting

Solutions for users for the optimum, manual ventilation of a building where turn-tilt fittings standard cannot be used due to the size of the window and the weight of the leaf. The interior design too often means that the window cannot be opened inward, or only to a limited extent. Turn fittings are a good alternative here which allow for the fast and inexpensive use of large window formats or greater weights with standard components. Alternatively, the outward opening turn fittings with security components and restricted opening angles provide interior designers with the greatest possible freedom for their designs.

Turn-Tilt Fitting Standard

The WSS-turn-tilt fitting system for windows made from aluminium profiles is based on design-oriented functionality. Corner bearings and turn/turn-tilt bearings in the same view and hinge parts flush with the window frame at the top and bottom underline the aesthetic design of the new WSS fitting system. This concept is rounded off by technical innovations.
The modular design based on the building block principle offers considerable savings in terms of warehousing, material planning and administration. The system with two stay sizes covers leaf formats up to 1,600 mm in width and 100 kg in weight. The fitting can be upgraded for a weight of 150 kg with an extension kit. The contact pressure is easily adjusted to allow for optimum tightness.
The opening width of 160 mm ensures high ventilation efficiency in the tilt position. An integrated lock prevents the leaf from accidentally shutting in the tilt position. Easy retrofitting or upgrading to higher resistance classes in accordance with DIN EN 1627 is possible. A clear commitment to functionality, design and ergonomics.

Turn-Tilt Fitting Heavy Duty

The heavy duty fitting has been developed to complete the new WSS window systems. This addition became necessary due to greater demands on security and thermal insulation whilst retaining the familiar leaf sizes. The new fitting has been designed for use with heavy and sturdy leaf elements up to 200 kg and leaf widths from 700 to 1,700 mm. Triple glazing or special glass, e.g. bulletproof glass, can be used depending on the size of the window. This fitting system is available in a modular design, just like the standard series. An extension kit allows for an easy upgrade to higher resistance classes up to RC3 (WK3).

Turn-Tilt Fitting Style 180

The concealed hinge side with no concessions in terms of comfort and functionality is required of modern window design. The concealed hinge sides only have an opening width of 90-100°, so that the leaf is in the room. An additional opening limiter is needed to prevent any damage to the fittings caused by excess pressure on the leaf. The new WSS turn-tilt fitting style 180° allows the leaf to be opened to 180°, enabling the required accessibility. The hinge parts are concealed, making the style 180° fitting not only an aesthetic but also a functional solution for modern buildings.

Tilt-Hung Fitting

Compared with turn/turn-tilt fittings, tilt fittings that open inward or hung fittings that open outward are the ideal way to achieve the best possible ventilation cross-section with floor-to-ceiling windows, without the space needed for a side-hung sash. Opening widths of up to 600 mm with lower operating force are possible for tilt leaves that open inward, so that the windows can also be operated easily by anyone with physical limitations. For personal protection reasons, the max. opening width of tilt windows has to be observed.

Fanlight Opener AK/AKL 210/300

The mechanical and electrical actuation of the new generation of fittings allows for easy opening and optimum ventilation by means of a hand lever, crank or electric drive for leaves weighing up to 80 kg.
The RAL-tested AK 210 fitting for tilt leaves and the AKL 210 fitting for hung leaves are suitable for use on aluminium, steel, plastic as well as wooden profiles and replace the AK 170/AK 230 and AKL 170/AK 230 fittings. The accessories from previous generations are in principle compatible with the new generation of fittings. Furthermore, the tried-and-tested AK 300 fanlight fitting with an opening width of 300 mm rounds off the product portfolio.

Top-Hung Fitting

The requirements of modern facades are characterised by a wide variety of functions, combined with the overall aesthetic appeal of the building envelope. Facade elements with large dimensions and corresponding leaf weights are not unusual on account of the architectural facade design and the resulting grid. These elements can be executed with modern top-hung fittings so that the desired architecture can be retained.
The geometry of the fittings optimizes the ventilation effect, fresh air flows in from below and spent air escapes from the top. The WSS top-hung fitting has been specially developed for extreme leaf sizes/weights and offers the best possible stability with a patented solution. The new swivel-mounted control stay secures the open leaf against lateral wind loads so that it is always held firmly. The lower opening width can be limited to 100/120 mm. With very heavy top-hung leaves, opening and closing of the element is assisted by spring elements, thus optimizing the operating forces.

Parallel-Opening Window

Complex stay technology for 17 mm profile chamber.
The parallel opening fitting (POW) is becoming increasingly important for building facades. The design, safety and noise protection requirements as well as the complete circulating ventilation function are crucial for this fitting solution. Due to the large stay dimensions, many POW fittings systems could only be used up to now in special profiles. Therefore, WSS has developed a stay geometry with a dimension (space requirement) of 23 x 17 mm. The combination of PX and PY stays and the complete stay design allows for secure and smooth movement of the leaf.
Resilient stay mechanisms of stainless steel allow for leaf weights of up to 150 kg, so that these can be easly opened and closed with little effort, even with manual actuation. Larger leaves of up to 250 kg are usually motor-operated. A further new development is the patented compact control stay that stabilizes the POW when open, so that it does not sway in the wind when open or during opening and closing.

Parallel-Opening Fitting for Ventilation Louvre

Largest possible ventilation cross-section with PO flaps.
A healthy room climate has to be ensured in high buildings with large glazed facades, too. This is done using narrow flaps with parallel opening fittings (250 mm visible width and 200 mm opening width), amongst other things. PO flaps can be opened manually with a concealed flap handle or motor-operated, e.g. via the building management system.
The parallel opening of the flaps results in an optimum, chimney-like ventilation because the spent air can escape upwards and fresh air can flow in from below.

Parallel-Opening-Top Fitting for Ventilation Louvre

Parallel opening louvre technology, opening inward, for high ventilation efficiency with a small flap size.
The new fittings system for parallel opening for ventilation louvre is a combination of a parallel fitting with an additional spring-assisted swivel technology. The louvre or flap is moved inward and down in a curved movement when opened.
This combines the advantages of the circulating, safe ventilation function with an enlarged ventilation cross-section in the upper flap area of a tophung fitting. The new system is based on solid stainless steel opening levers that replace the former stay technology. In addition, the opening levers are fitted with an adjustable, integrated brake device and supporting springs to ensure easy operation when opening and closing the louvres. The concealed installation of the opening mechanism and operating lever that is integrated flush in the front of the louvre help retain the discreet aesthetic look of the overall element. Motor-operated louvres are driven by concealed spindle drives inside the louvres.

Turn Fitting for Ventilation Louvre

Turn louvres are an efficient solution for ventilating large glazed facades. With a min. flap width of 300 mm, the necessary ventilation cross-sections can be created very easily. The slim louvres hardly have any impact on the facade appearance. Different limitation options are needed to limit the opening of very slim louvres, where an opening limiter cannot be used for space reasons.

Slide-Turn Fitting

Slide-turn fitting for narrow windows and ventilation flaps. Narrow, floorto-ceiling windows and flap elements have proven themselves time and again for natural ventilation in modern facade technology. The concealed solution combines high ventilation efficiency, the necessary level of safety and an aesthetic appearance. In its opening position of 90° and in the locking position, the fitting meets the DIN EN 12600 standard for flap widths with a clear opening of up to 100 mm.
The fitting is ideal for straight, narrow and floor-to-ceiling ventilation elements. In contrast to conventional fittings, extremely narrow profile views are possible thanks to the concealed guide rails and sliding carriage.
The fitting has been visually upgraded since only filigree reels are visible at the top and bottom that match the profile in colour and are hardly visible.
The slide-turn fitting can be used with any system and for window profiles with a Euro groove.

Vertical-Slide Fitting

This fitting is the perfect solution where a parallel-opening fitting (PAF) or a top-hung element cannot be used on account of external protection against the sun, or inward opening is not possible on account of the necessary space requirement.
In a vertical-slide fitting, two leaves lie on top of each other when closed.
The lower leaf can be unlocked with a handle and pushed upwards. The lower leaf is connected to the upper leaf by concealed steel cables and pulleys, the upper leaf then acts as a counterweight. If the lower leaf is pushed upwards, the upper leaf moves down. The inner leaf is guided by lateral guide rails so that both leaves can pass each other. The opening is limited in the central position - when both leaves are at the same height. Ventilation is through the openings above and below the leaves in the facade element.
As an option, each leaf can be tilted inward independent of the other leaf. In this case, the leaves are limited by security stays at an oblique angle of 30°.
