Moondream Soundproof Curtain

Moondream's reversible 4-in-1 Room Divider Curtains use our own patented technology (U.S. Patent N° 9475260) with 4 layers of strategically assembled materials to obtain the best results in sound insulation that can be achieved with a fabric curtain: identical blackout fabric on each external side, one metallized thermal-insulating lining layer and one thick cotton layer inside. The curtain absorbs and stops the passage of sound waves and also provides a thermal insulation against heat and cold as well as a 100% blackout effect.

The room divider curtain can act as a wall to muffle high frequency noise such as voices. As the curtain looks identical on both sides, it is the ideal replacement for a door or as a mobile partition wall. Create an additional room and block out the surrounding hustle and bustle with just one draw of the curtain.

Our product has been tested by independant laboratories to confirm its sound, thermal and light insulation perfomance:

  • Noise insulation: Sound energy is divided by eight, reaching a drop of up to 9 decibels (1). Reverberation of sound in the room is also reduced and creates a quieter atmosphere, e.g. for a surface area of approximately 215 ft² the reverberation time is reduced by 0.4 seconds (2).
  • Thermal insulation: Up to 37% reduction of heating costs in winter (3) and a drop in temperature during summer (4).
  • Light insulation: 100% blackout effect for improved sleep quality.


(1) Test performed by the CEBTP laboratory in accordance with European EN ISO standard 717-1, report no. BEB2.F.6011-2 dated 04/27/2015
(2) Test by the Experimental Center for Building and Public Works Research and Studies (CEBTP), experimental report no. BEB2.E.6039-1

They just weren't the right thing for soundproofing

I am very pleased with their performance. We hung them midway between floors in the stairwell. I am no longer bothered by the tv and other noise from activities in the basement, and I couldn’t be happier with this purchase. The curtains are heavy and I used two in the 46” wide stairwell. They definitely dampen sound to a significant degree and they are complete blackout curtains although I don’t need that feature where these curtains are placed

These curtains are much higher quality than I anticipated. I'm using them to decorate the whole perimeter in a home theater and they're up to the task. They muffle the sound, help insulate, and look great.

I desperately needed something to squash the street noise I was suffering living here in San Francisco and I found the answer with these roomdividers/curtains. The difference in noise level is incredible. I went from always being irritable in my home because of annoying street noise to blissful calm. I smile more often in my home now, THANKS Moondream!!

These room dividers have elevated my garage into a multi purpose space free from the washer and dryer noise. A joy to have hanging!

Exactly what I wanted to deaden the noise going into our game/media room. I like how it folds up nicely against the wall, when not in use too. Looks great too!
