The frameless glass elements and barrier freedom in the threshold create an elegant, transparent appearance with an unobstructed view of the outside area. Integrated soft-close mechanisms enable the sashes to be opened and closed gently and safely, while durable stainless steel running rails and sash carriers ensure long-lasting, comfortable operation. An integrated dirt drainage system also makes cleaning and maintenance easier. With heroal S 20 C, various types of opening and large areas of up to 14,400 x 2,500 mm can be realized. The up to five individual glass elements can be between 60 and 1,200 mm wide and weigh up to 100 kg. The sliding glass wall is perfectly matched to the heroal OR patio roof system, but can also be used for other applications. Retrofitting is also possible without any problems – for flexible, weather-independent outdoor living spaces. heroal S 20 C > Patio canopy heroal OR >
+ Maximum transparency thanks to frameless sashes. + Reduction of drafts through transparent sealing strips. + Elegant shell handles made of brushed stainless steel. + Perfect running characteristics thanks to precise adjustment options for the units. + Flat threshold combined with effective drainage using the heroal DS drainage system. + High ease of use thanks to additional pull-in dampers. + Maximum element width of up to 14.4 m.
Optional accessories such as transparent sealing strips effectively reduce drafts and optimally seal the clearances between the glass elements. They ensure a pleasant indoor climate when closed—without impairing visibility. Thanks to their delicate, UV-resistant version, they blend inconspicuously into the frameless all-glass sliding wall system and are ideal for permanent use outside.
The precisely adjustable carriages guarantee smooth, jerk-free movement of the glass units up to a sash weight of 100 kg in the robust stainless steel rail. Each unit glides smoothly and quietly, which not only increases ease of use but also extends the service life of the entire System.
Optional accessories such as integrated soft-close mechanisms automatically and gently pull the glass panels into their end position. This ensures that the units close in a controlled and quiet manner without damaging the glass or fittings. At the same time, the dampened movement protects against finger pinching or injuries – for added security and comfort with every use.
The heroal S 20 C sliding glass wall meets the requirements of DIN 18040-1/2 for barrier freedom. The optional integrated heroal DS drainage system reliably drains rainwater and surface water and prevents waterlogging. The elegant cover in stainless steel look blends harmoniously into the overall design and underlines the high-quality workmanship.
An optional lock protects the heroal S 20 C sliding glass wall against unauthorized access. The lock can be conveniently operated by hand or foot from the inside, providing additional security without compromising the clear appearance of the sliding glass wall.
Weather protection With a sliding glass wall from heroal, you can transform your patio canopy into a comfortable place to relax, whatever the weather. The heroal S 20 C all-glass sliding wall system provides reliable protection from wind and driving rain while allowing an unobstructed view of the garden. Thanks to the flexible, movable units, you can open your canopy partially or completely at any time – for perfect protection in all weather conditions.
Noise protection Create an oasis of calm – even in busy surroundings. When closed, the heroal S 20 C sliding glass wall has a sound-absorbing effect and reduces disturbing ambient noise such as street noise or neighborhood noise. This allows you to enjoy relaxing hours on your patio, have undisturbed conversations, and spend time outdoors in pleasant tranquility – regardless of external influences.
Heat accumulator Enjoy pleasant temperatures even after sunset. When closed, the sliding glass wall stores the heat of the day and keeps your summer garden pleasantly warm until late in the evening. This allows you to extend your patio season and create a place to relax—all year round.
Insect screen Whether you're having breakfast or enjoying a leisurely dinner outdoors, a closed sliding glass wall keeps mosquitoes, wasps, and other insects outside. This allows you to enjoy your patio undisturbed and spend your time outdoors in complete relaxation.
Flexible conservatory alternative In combination with a patio canopy or balcony overhang, your sliding glass wall becomes a flexible conservatory solution. This creates a weather-protected summer garden that extends your living space and can be used all year round – with the lightness and openness of a transparent glass room.
