Great product

I bought 4 of these in 108" length to cover the entrance leading to a glassed in conservancy area. This 4-sided glass enclosure projects 3' out from the side of the building, is 10' wide and has an half-round roof made of fiberglass that reaches 12' high. While the doors are newer and double-paned, the rest of the glass is not and as a result this bump out (I am in Boston) is C-O-L-D. As it is on one side of the bedroom, BRRRR. I hung a ceiling mounted rod and the curtains went up in short order. Not only are they thick and very well constructed, they are fantastic at light blocking and have to date (I installed them in Oct. 2015 it is now mid-Nov.) demonstrated a temperature differential on either side of up to 10 degrees - WOW! I am ordering another set for similar sliders on the opposite side of the house. Well worth the investment!
