Product Description

Beauty meets function. AlphaSorb® Designer Premium Acoustic Felt Ceiling Clouds (formerly Series 300) are a decorative, sound-absorbing ceiling treatment offering visual appeal through color, texture, and shape. Our acoustically superior recycled PET felt works in tandem with our uniquely designed internal air cavities to provide excellent acoustical benefits for open spaces. Our felt clouds can be ordered in round or square shapes in a variety of colors, giving you endless design possibilities.

Like our other premium felt products, these ceiling clouds are incredibly popular among architects and designers because they are a modern, eco-friendly way to mitigate noise and reverberation with a one-of-a-kind design appeal. Our premium acoustic felt is 100% PET plastic from recycled bottles, 100% recyclable, and eligible for LEED (Leadership in Energy and Environmental Design) MRc4 credits. It’s a polyester material with a felt-like finish in over 30 heathered vibrant hues. The material is porous, fire-rated, environmentally responsible, long-lasting, and easy to maintain and hang — making it well suited for acoustic treatments in both commercial and residential settings.
