Linen Look 100% Blackout Curtain 100x84 Inch Extra Wide Patio Sliding Door Curtain Solid Thermal Insulated Room Curtain for Bedroom, Living Room (1 Panel, White)

A white curtain that genuinely blacks out is unusual, because the normal way to stop light is a dark lining that shadows through pale fabric. This one puts a white coating on the back of a linen-look polyester face, so the panel stays white from both sides and still keeps sunlight and UV out completely — day turned to night, and furniture and floors spared the fading that comes with a sunny room.

At 100 inches wide by 84 long it is one panel for a patio slider, a wide bedroom window, or a doorway, carried on twelve anti-rust grommets with a 1.6-inch inner diameter that run smoothly on most rods. The face has a burlap effect and real drape, closer to vintage linen than to a technical curtain, and the thickness does the quieter work: insulating the glass against heat and chill, cutting noise, and keeping the inside of the room private.
