THE ULTIMATE 100% BLACKOUT CURTAINS: These luxury curtains are treated with our light blocking technology for 100% light filtration, which also gives structure and thickness to the curtains. THERMAL INSULATION: The unique insulating weave of our curtains helps to trap heat or cold air so that your room stays at the ideal temperature all day or night long. GROMMET HEADING: Phyllis utilizes a grommet heading which is user-friendly, adjustable, and most importantly it has a straight and crisp fall leading to a neat and tidy look for the curtain. SOUND FILTERING DESIGN: Our noise-canceling curtains help keep sound out so that you can get a peaceful night’s sleep without hearing the construction work outside, the neighbor’s dog barking, or other disruptive sounds.
