Frequently Asked Questions
Are these curtains true blackout?
These BGment panels are designed for room darkening and many users report significant light reduction, but performance varies by color, fit and window setup. Darker colors and properly sized panels (1.5–2x window width) block the most light; some customers still notice edge leakage, so add liners or overlap panels for near-total blackout.
How do I measure for the right panel length and width?
Measure the full width of the window including trim; multiply by 1.5–2 to determine total fabric width needed. For length, measure from the rod location to where you want the curtain to end (just above the floor is common). Choose panel widths and a number of panels that together reach your target total width.
Can I machine wash these curtains?
Yes — the manufacturer lists machine washing on a gentle, cold cycle and recommends no bleach, warm ironing if needed and tumble drying at low temperature. Always follow the care tag on the panel to prevent shrinkage or damage.
