FAQs
Yes. While the exterior features a sophisticated, natural linen weave for an organic look, the interior is bonded with a high-density, opaque blackout coating. This dual-layer construction effectively blocks 99% of external light, offering the privacy and darkness required for bedrooms and home theaters.
The Square Cassette offers a clean, minimalist profile that conceals the roll mechanism and hardware. Beyond its modern aesthetic, the cassette box protects the fabric from dust, debris, and pet hair, ensuring your linen shades remain pristine and operate smoothly for years.
Yes. Our premium cordless system uses a high-precision, constant-tension spring motor. By eliminating all dangling lift cords or chains, it removes common entanglement hazards, making it the safest, most minimalist window treatment choice for households with children or pets.
To ensure a flush, secure inside-mount installation of the square cassette, we recommend a minimum window frame depth of 10cm (4 inches). This provides adequate clearance for the mounting brackets and the cassette box to sit neatly within your window frame.
For inside mounts, measure the width of the frame at the top, middle, and bottom; use the narrowest measurement for your order. For height, measure from the top of the frame to the sill. See Our Step-by-Step Measurement Guide.
Yes. These shades are versatile and suitable for outside mount (on the wall or frame surface). We recommend adding at least 5–10cm (2–4 inches) to your width and height measurements to ensure maximum light coverage and minimize light leakage around the edges.
Routine maintenance is simple. Gently vacuum the fabric with a soft brush attachment on a low-suction setting to remove dust. For spot cleaning, use a slightly damp microfiber cloth to dab the affected area; avoid harsh chemical cleaners or vigorous scrubbing, which could compromise the blackout backing.
Yes. Every shade ships with a complete installation kit, including high-durability mounting brackets, wall anchors, and screws suitable for both inside and outside mount configurations, ensuring a professional, stable installation.
