KELLER minimal windows® highline 4+

System glass façade between two floors made from insulated, concealed aluminium frame profiles. Interior view in post-free glass-to-glass butt-jointed implementation or with a minimalistic facing width of the vertical junction and design post profiles of only 22 / 26 / 34 mm, depending on the system variant. Glass façade in 2 tracks, flush-mounted or recessed, made from storey-high fixed glazing with integrated, slender design sliding doors and sliding windows in the inner track.

Design features:

Complete integration of the all-round, thermally isolated frame profiles into the floor, wall and ceiling is possible.
Barrier-free floor area, manufacturable without threshold, system configuration in 2 tracks.
Mitred, all-round outer frame provided with 34 mm insulation bars per track with screwed corner connectors. Leaves are structurally glued to the glass all round.
Self-centring, dual-track, stainless steel castors integrated in the leaf and guided by high-alloyed, dual-track, thermally isolated, 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 locking integrated as standard in the sliding leaf.
Locking position(s) freely selectable in the grip and junction profile of the sliding leaf.
Stability of the sliding system tested under extreme wind loads with a nominal load of 2,000 Pa (approx. 200 km/h) and a peak load of 3,000 Pa (approx. 250 km/h; with brief gusts of wind) in accordance with EN12210 and the classification C5.
