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.

Turn the handle

Stage one

Turn the handle

90° on the lockable cylinder handle. The carriage releases. The panel is yours to move.

A4 stainless handle, child-safe lock standard. Anti-lift catch engaged when closed.
Pivot perpendicular

Stage two

Pivot perpendicular

The panel rotates 90° from the wall plane to perpendicular. Eight polyamide bearings carry the weight — silent.

8 bearings per wing: 4 top conveyance, 4 bottom guidance. Stainless brackets, CE-rated wheels. 5-year warranty.
Slide along the rail

Stage three

Slide along the rail

Push. The carriage glides along the anodized track. Each panel follows, edge-on, stacking at the parking zone.

Up to 22 panels per opening, 700×3000mm each. Stack depth 5–7cm. 100% opening — the wall becomes air.
Magnet click

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.

U=1.4 W/m²K

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.

Method

We write what's bad.

Every system page has a cons section. Transparent prices that don't shift after the contract is signed. No PVC hardware at Premium pricing. This is rare in Batumi — and our key differentiator.
