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.

I bought 2x 50" curtains for a 50" doorway to the bedroom (the apartment has a very open layout, no door to the bedroom) The extra folds in the fabric definitely contribute to noise dampening help. The bf & I are both really happy with the results. The bedroom isn't silent, but it's enough that he can watch tv upstairs & the voices aren't crystal clear downstairs, so I can read and fall asleep just fine.

The curtains are very heavy and really well made! I am using them on the back of my home mixing studio for acoustic control. They are very effective in dampening the reflections and reducing the reverberation in the room, improving the response of my speakers. That being said, they worked for me because I was not expecting them to do any kind of soundproofing. Keep in mind that soundproofing requires much higher mass, and any air gap will significantly reduce the effectiveness of sound proofing. It is just impossible to achieve soundproofing with curtains. Bricks, concrete, drywall, and specialized windows are needed for that. These curtains should be called "sound absorbing curtains" and not "sound-proofing curtains", as the latter title can be misleading.

Fabric is thick and high quality. Looks great in our house. Not convinced it is blocking sound though. Overall happy with the purchase.
