Eclipse Zodiac Energy-Efficient Curtain

I live in a drafty apartment. I have used the Eclipse Zodiac curtains in my living room to help block out the sun in the summer and keep drafts to a minimum in the winter. I bought this panel at a longer length to cover the AC unit that is wall mounted. It tends to get quite drafty in the winter months. The longer length covers the unit nicely and has cut back on the draft.

Because I couldn't decide on a look, I bought these Zodiac curtains in the tan color and also the plain black Eclipse blackout curtains (with a pleated top). I hung both to get a feel for my room. I definitely loved the look of these much more than plain black curtains, but I can say there is definitely a difference in how both block light. I'd agree that the plain black curtains by Eclipse are 100%/99% blackout, but the tan curtains may only be 85% blackout. Still, this makes a HUGE difference in my bedroom.
