27A Electric Built-in Louvered Insulating Glass

Description

The 27A Electric Built-in Louvered Insulating Glass integrates a magnetic-controlled louver system inside the sealed chamber of 27 mm hollow layer insulating glass — raise, lower and tilt the blinds without ever cleaning them and without cords in the room.

Control

Multiple control options: traditional 220 V wiring (wall switch, split wireless receiver, smart home) or light-energy solar drive.

Specification

• Glass build-up: 27 mm hollow layer
• Hollow layer: 27 mm
• Max area (single pane): wide-area units
• Max width / height: large width / large height
• Min width / height: — / —
• Louver: 12.5 mm magnesium-aluminium alloy slats, 17 colors (see Louver Selection)

Why the sealed unit performs

• Four-sided molecular-sieve warm-edge spacer, dew point ≤ −60 °C — no internal condensation
• Invisible guide rail, almost flush with the glass — matches system windows and doors
• Remountable magnetic handle, factory or on-site installation
• Patented auto-levelling device prevents tilting and jamming
• 90° corner joinery with patented dynamic suspension angle correction

Measured performance (27 mm hollow layer)

• Shading coefficient (Sc): 0.84 fully retracted / 0.41 at 45° / 0.29 fully closed
• Heat transfer (U-value): 2.05 W/m²·K fully closed / 2.50 W/m²·K retracted
• Visible light transmittance: 81%
• Service life: 60,000 lift-and-tilt cycles (33–40 years at 4–5 ops/day)

Ordering

The 27 mm chamber accepts wider louvers and larger glass units — send us the opening dimensions and control preference for a configuration sheet.

Louver colors & slat options

All 19A / 20A / 21A / 27A units use the same slat system: 12.5 mm × 0.2 mm and 16 mm magnesium-aluminium louvers, selected by color code at order time.

Color codes: SX12501, SX12502, SX12503, SX12504, SX12505, SX12506, SX12507, SX12508, SX12509, SX12510, SX12512, SX12513, SX16001, SX16002, SX16003, SX16004, SX16005.

Size limits for built-in blinds units

• Single width: max area 2.2 m², max width 1.5 m, max height 2.4 m
• Double width: max area 4 m², max width 2.5 m, max height 2.4 m
• Electric single: max area 6 m², max width 2.3 m, max height 2.6 m

Performance (5 mm tempered + louver + 5 mm tempered)

• Shading coefficient SC: 0.84 retracted / 0.41 slats at 45° / 0.29 fully closed
• U-value: 2.05 W/m²·K closed / 2.50 W/m²·K retracted
• Visible light transmittance: up to 81%
• Service life: 60,000 raise/lower cycles tested — approx. 33–40 years at 4–5 uses per day
