Slide and Turn-Systems

Loggia glazing

Loggias are often the architectural centerpiece of a facade, but are rarely used in wind and rain. The SUNFLEX slide and turn system transforms the loggia into an inviting, weather-protected living area without obstructing the view. In good weather, the glass panels can be slid to the side, allowing the loggia to open almost completely and feel truly refreshed. The system's exceptionally compact design ensures that even narrow loggias can achieve their maximum possible opening width. The minimalist, frameless design allows for an unobstructed view even when closed.

Balcony glazing

A glazed balcony that can be fully opened in summer is a true space-saving concept. The SUNFLEX sliding-folding systems can be installed around corners (angles between 90° and 180°), making them ideal for balconies with an L-shaped layout or corner balconies. The frameless design of the SF25 and SF30 ensures that the balcony offers a light-filled feeling even when closed, and allows for breathtaking panoramic views.

Terrace roof and summer garden

The SF30 is particularly effective as side glazing for a SUNFLEX terrace roof: all three open sides of a terrace roof can be stylishly glazed with the slide and turn system. Under optimal conditions, 26 panels (13 on the left and 13 on the right) are possible. Corner installations at angles between 90° and 180° are also easily achievable, and the stainless steel tracks can be installed flush with the floor. This creates a spacious summer garden that can be fully opened, blurring the lines between indoors and outdoors.

SF25, SF30, and SF35 are glazing systems for loggias, balconies, and the side glazing of terrace roofs. The principle is the same for all three systems: The operating panel is unlocked with a handle and pivoted either inwards or outwards. All other glass panels can then be slid to the side on the single-track bottom rail and parked as a compact unit. These sliding-folding systems allow for complete opening of the glazing, offering an unobstructed panoramic view. The panel configuration and sliding direction are freely selectable.

All three systems share the same technical foundation: a completely rustproof carriage system with needle bearings and polyamide rollers, a double brush seal at the top and bottom of each glass panel, a double locking mechanism, and the option of recessing or surface mounting the bottom rail. Individual glass elements can be replaced at any time. All systems are available as either a frameless all-glass construction or a framed aluminum construction and can be installed around corners or curves between 90° and 180°.

The systems differ in their guidance system, installation height, and glass construction: The SF25 is suspended and offers a virtually invisible, frameless, all-glass appearance up to a height of 2.8 meters. The SF30 is vertically guided, reaches a height of up to 3.0 meters, and enables particularly impressive panoramic fronts of up to 26 meters. The SF35 complements the suspended construction with insulated glazing for enhanced sound insulation and an optional gap seal for improved airtightness.

Suitable for:

• Loggia glazing
• Balcony glazing
• Side glazing of patio roofs
• Projects with corner geometries and arched shapes (90° to 180°)
• Systems designed to open fully

Not suitable for:

• Projects requiring high thermal insulation (e.g., heated conservatories). The SUNFLEX SF60 / SF80 sliding window systems are recommended here.

The defining feature of slide and turn systems is the combination of rotation and sliding: Each panel rotates individually outwards and can then be slid to the side. This allows the entire front to be almost completely opened. With the SF20/SF22/SF42 sliding systems, the glass panels are moved linearly without a rotation mechanism. A portion of the opening width always remains occupied by the sashes' parked position. With the slide and turn systems, the framed glass panels are folded like an accordion. The sliding window systems, with models SF40/SF60/SF80, offer various levels of thermal insulation as well as RC2 burglar resistance and are the right choice when thermal separation and security are paramount.

Loggias and balconies often go unused in wind and rain because they are too cold, too noisy, and too exposed. Standard systems don't offer the desired solution, as their wide frames obstruct the view or prevent them from opening fully. Glazing with SUNFLEX sliding-folding systems solves these problems:

• Weather protection without restrictions: When closed, the glass reliably protects against wind, rain, and noise. At the same time, the frameless design offers an unobstructed view. So you can enjoy your coffee even in the rain without getting wet.
• More usable space: Loggias and balconies are transformed into fully-fledged living spaces that can be furnished without worrying about water or wind damage. Your favorite furniture can now remain outdoors in all weather.
• Simple cleaning: Because the glass panels can be rotated individually, cleaning is particularly easy. A drip tray reliably drains away cleaning water and condensation.
• Maximum opening width: When opened, the system disappears sideways as a slim package, completely clearing the passageway. The stainless steel tracks can be installed flush with the floor, blurring the boundary between indoors and outdoors.
• Suitable for any floor plan: Whether rectangular loggia, corner balcony, L-shaped floor plan or polygonal arch shape, the sliding-rotating systems can be configured via angles between 90° and 180° as well as for curved facades. 
• Noticeably more peace and quiet: With airborne sound insulation up to Rw = 34 dB (SF25) or Rw = 30 dB (SF35), the exposed outdoor area becomes a quiet, protected living space.
