KELLER minimal windows® highline


Aluminium double glazed window



Aesthetics, combined with high performance features communicate the clean minimalism of our system glass façades.‎ All elements are intrinsic components in modern architecture.‎
The system glass façade profiles between the two storeys comprise insulated, concealed prone aluminium frame profiles and are ideal wherever minimal profile facing widths and maximum window height are required.‎
The flush-fitting or offset-surface grass facade can be combined on request with slimline design sliding doors and is the perfect solution for high-quality double-glazed residential and commercial buildings.‎

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 25 mm insulation bars per track with screwed corner connectors. 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 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 C4/B5.
