Design features

Complete integration of the all-round, thermally isolated frame profiles into the floor, wall and ceiling is possible.

Barrier-free floor area, implementable without threshold.

System configurations up to 4-track systems, solutions free of corner posts, all-glass corners and wall integration of the sliding leaf.

Mitred, all-round outer frame provided with 25 mm insulating bars per track with screwed corner cleats. Leaves are structurally glued to the glass all round.

Self-centring, single-track, stainless steel castors integrated in the leaf and guided by high-alloyed, stainless steel running rails of the lower outer frame profile.

Substructure with PVC hollow-chamber drainage integrated in the system for support of the weight and controlled drainage in a downward direction. Substructure profile with holding groove for EPDM film connection.

Manual 2-point bar lock integrated as standard in the sliding leaf.

Locking position(s) freely selectable in the grip, double-vent and coupling profile of the sliding leaf.

Tested stability of the sliding system under extreme wind loads up to 200 kg/m² (> 200 km/h) in accordance with EN12210 and the classification C4/B5.
