Description
The 19A Magnetic Control Built-in Louvered Insulating Glass (QI Series) integrates a magnetic-controlled louver system inside the sealed chamber of 5 + 19A + 5 mm tempered insulating glass — raise, lower and tilt the blinds without ever cleaning them and without cords in the room.
Control
Magnetic transmission: the external magnetic handle drives the louvers through the glass — no cords, no holes.
Specification
- Glass build-up: 5 + 19A + 5 mm tempered
- Hollow layer: 19 mm
- Max area (single pane): 3.6 m²
- Max width / height: 1800 mm / 2700 mm
- Min width / height: 230 mm / 340 mm
- 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 (5 + 19A + 5 mm tempered)
- 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)
