Through the glass.
Outside to inside,
in a single move.
Longevity
Anodized BKS profile service life on the Batumi coast.
Insulation
ICS heat-insulated U-value — like a modern apartment window, year-round.
Opening
Frameless folding: panels pivot 90° and stack at the edge.
Material
Anodization
A protective layer that doesn't chip. It grows from the metal itself.
Electrochemical process turns aluminum surface into Al₂O₃ — ceramic, 15-25 micrometers deep. BKS profile colors: mill, anodized natural, bronze, RAL custom. Accessories in black for contrast. Stainless brackets, CE-rated polyamide wheels. Service life on the Batumi coast: 30+ years.
Operation
Four gestures: how a balcony becomes a terrace
One BKS frameless folding system. Four stages of the same operation.
Stage one
Turn the handle
90° on the lockable cylinder handle. The carriage releases. The panel is yours to move.
Stage two
Pivot perpendicular
The panel rotates 90° from the wall plane to perpendicular. Eight polyamide bearings carry the weight — silent.
Stage three
Slide along the rail
Push. The carriage glides along the anodized track. Each panel follows, edge-on, stacking at the parking zone.
Stage four
Magnet click
Closing: panels meet, the BKS magnet seal catches. A slim dark line — no rubber bulb, no exposed gasket. Outside: rain. Inside: silence.
ICS thermal-break + 20mm double-glazed unit.
One system. Four gestures. Three tiers below.
Glass
Glass that holds the sea
Magnet seal between panels — a slim dark line, no rubber bulb. Thermal-break profile, ICS double-glazed.
BKS magnet seal — the signature look: panels meet at a thin dark seam, no exposed gasket. Thermal break severs the cold bridge. ICS double-glazed unit (4+12+4mm) holds a 12–15°C improvement over standard 8mm closure. Outside: rain. Inside: silence.
