SL 23 balcony glazing
Non-insulated all-glass sliding glazing that protects balconies and loggias from wind, weather and noise
The SL 23 is a non-insulated all-glass sliding system for balconies and loggias. It is mounted in front of the guardrail and uses linear glass panes fixed in aluminium profiles at the top and bottom, so the balcony keeps its transparency.
The system is designed to meet the static requirements and the visual demands of modern architecture, particularly on higher levels. Simplified self-opening and an integrated soft-close lock make the panels easy to handle despite their weight.
The SL 23 is available in 2 and 3-track versions and can accommodate structural tolerances with 12 mm of lowering and 5 mm of raising.
