Need Daylight by Day and Darkness at Night? Layer Sheer and Blockout Curtains
Sheer and blockout curtains solve it: a sheer for soft daylight and a blockout for darkness on one double track.
A sheer alone will not darken a room, and a blockout alone makes it dark by day. A bedroom needs darkness for sleep and soft light in the morning. A street-facing living room needs privacy by day and at night. A sunny room needs the sheer for glare and the blockout for the hottest hours.
Layered curtains give you both. Most homes leave the sheer across all day, then draw the blockout at night, and open both for the view.
Double curtains, also called curtains with sheers or sheer curtains with blockout, put both on one window.
How Sheer and Blockout Curtains Work on a Double Track
A double track holds two curtains, one behind the other, and each runs on its own track so you can draw one, both or
neither
That is how to layer sheer and blockout curtains. The window needs room above for the double curtain track, and room either side for both curtains to stack back, meaning the space they take up when open.
The measure also checks clearance from handles and the reveal depth, which is how deep the window recess is.
Fullness is how much fabric goes into each metre of track, set for each layer. A track does the job of a double curtain rod and lets both curtains glide.
Light can still show at the edges and top, so a ceiling fix or a pelmet reduces light gaps.
Dual Curtains or a Double Roller Blind?
Both give two layers at one window. Curtains are softer and hold more warmth, while a double roller blind is compact and sits inside or on the window frame.
