FAQs
Yes. We use a high-density, multi-layered construction where an authentic linen-blend surface is bonded to an opaque, light-blocking backing. This combination provides the sophisticated, organic texture of linen while effectively blocking 99% of external light and UV rays, ensuring a dark and private environment.
The Square Cassette (top box) offers a clean, contemporary, and architectural finish that completely conceals the roll mechanism and hardware. It also serves as a protective dust cover, keeping the textured linen-blend fabric clean and pristine when the shade is retracted.
Yes. Our premium cordless mechanism uses a precision-engineered, constant-tension spring motor. By removing all dangling lift cords or chains, we eliminate the primary entanglement hazard, making it the safest window treatment choice for homes with children or pets.
To ensure the square cassette fits securely and sits flush within your window frame, we recommend a minimum installation depth of 10cm (4 inches). This provides sufficient clearance for the mounting brackets and the cassette profile.
For inside mounts, measure the precise width at three points (top, middle, and bottom) and use the narrowest measurement. For height, measure from the top of the frame to the sill. See Our Step-by-Step Measurement Guide.
Yes. Outside mounting is ideal if you have shallow window frames or want to maximize light coverage. We recommend adding 5–10cm (2–4 inches) to your width and height measurements to ensure the cassette box fully overlaps the window opening for optimal light blocking.
Maintenance is simple. Use a vacuum with a soft brush attachment on the lowest suction setting to gently remove surface dust. For spot cleaning, dab the area with a slightly damp, clean microfiber cloth. Avoid harsh chemicals or heavy scrubbing to preserve the integrity of the blackout backing and linen texture.
Yes. Your order includes a complete, high-durability installation kit with mounting brackets, wall anchors, and screws, designed for quick and professional-grade installation on both inside and outside mounts.
