SL 25 Framed Slide-Swing system

Transparent balcony glazing system consisting of independently moveable panels with tempered safety glass in a non-insulated, aluminium framed system. Applications include balcony fenestration, conservatories, swimming pool enclosures, terrace glazing and residential façades.

The panels are held at top and bottom in aluminium profiles by a combination of concealed clips and adhesive. At least one panel functions as a door, the remaining panels are slid individually to the opening spot, where they automatically snap into place and can then be opened by turning.

The doors interlock by concealed upper and lower plastic locking mechanisms, which operate by a filigree steel cable on the inner side of the system. Low-maintenance, low-rattle, rustproof and foolproof fittings concealed within the profiles ensure system stability.

The frame width can be adjusted by ±15 mm on each side during installation.

The SL 25 Framed Slide-Swing system can be combined with the parapet, fixed and tilt-turn elements of the SL 45 system.
