Whisperwave® Ceiling Cloud curved accent products allow you to unleash your creativity while reducing noise and reverberation. Add dimension and acoustical control right where you need it the most with Whisperwave® Ceiling Clouds.

Whisperwave® acoustical foam clouds are available in natural white, natural grey and HPC coated colors. The HPC coating is applied to all surfaces of the cloud. Made from Class 1 fire-rated melamine foam, Whisperwave® products are offered in standard sizes or they may also be customized for specific project requirements.

Whisperwave® Ceiling Clouds are lightweight and easy to install. Suspend these ceiling clouds using 1.5″ corkscrew hangers & cable (sold separately). The corkscrew hangers pierce and screw into the back of the foam cloud to provide an attachment point for wire or cable. Appropriate hardware to mount cables or wire to your ceiling may be purchased locally or provided by your installer.

  18. Verified Customer

    Long story short – AMAZING! RECOMMEND! BUY WITHOUT HESITATION! My Story: i have living room with hardwood floors so the sound was bouncing all over and reverb issue was a disaster. Plus i do have some minor hearing loss which makes it impossible to hear anything when reverb is present – thats usually the case with minor to moderate hearing loss, i can't hear what people are saying and keep asking to repeat what they just said, watching tv was impossible, volume over 50 was the only way but it just made more acoustical disaster in my room… so at first i bought a huge rug but it only fractionally improved my sound in the room so i decided to look further. After some research and hesitation i ordered these whisperwave clouds and when i took them out of the box i couldn't believe how much sound they absorb, you literally could not just hear but feel the difference just by standing next to them, they were like black hole for sound!!!! i have no idea what this foam is made of but i am very impressed, i sort of want to create the whole cave out of them and just sleep in it! haha So, i installed these 4 panels on my ceiling, i used 3M command sticky strips and hooks to mount them and i still can't believe that these 4 panels fixed my problem! sound – smooth, no reverb! watching tv is possible at volume 10-15!!! having simple conversation – like it supposed to! Having people over for glass of wine and a chat is very enjoyable and no one has to scream over each other anymore! i absolutely recommend this product and company! these guys delivered these panels fast too! already considering another panel set for my bedroom because of the similar issue so most likely will buy something again! thank you for making my life in my living room so much more enjoyable!!!!

  19. Verified Customer

    I wish I would have gone with white, but I think these will be easier to keep clean. Easy to work with and install.

  20. Verified Customer

    I have this produce installed in a project studio and not only does it focus the sound, it gives the room a modern look which I haven't seen often in smaller studios. The light weight and supplied hooks made installation easy. Looking forward to mixing under these.

  21. Verified Customer

    and here we go again …..

  23. Verified Customer

    It worked well to knock down the echo and looks good…

  24. Verified Customer

    Clouds were a great help to our all glass conference room. They are not only functional but everyone thinks that they are floating art sculptures. Form and function.

  25. Verified Customer

    You need a lot of them to do the job

  26. Verified Customer

    very effective in controlling echoes in my classrooms

  29. Verified Customer

    Easy to install

  30. Verified Customer

    The acoustical wave tiles were used in a bar restaurant in ***.
    The tiles added a nice design feature to the ceiling as well as doing their job of sound control.
    Simple to install and very easy to cut if you need to adapt to space.

  31. Verified Customer

    Quality seems great
    Look is really cool, man.

    Product looks great after installed, but much more fragile that anticipated during the installation process. Had to wear cloth gloves because they get dirty very easily.
