Product Description

The Superior Acoustical Ceiling Baffle. AlphaSorb® Designer Premium Acoustic Felt Ceiling Baffles are constructed with two layers of 9mm PET Board. These panels are a polyester material with a felt-like finish and come in over 30 vibrant heathered and solid hues and a variety of shapes and sizes. Better yet, they have been designed to include an air cavity for enhanced acoustical performance offering a Noise Reduction Coefficient (NRC) rating of 1.10.

These felt baffles (formerly called AlphaSorb® Series 300 Acoustic Polyester Acoustic Baffles) are incredibly popular among architects and designers because they are a modern, eco-friendly way to mitigate noise and reverberation. 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. The material is porous, fire-rated, environmentally responsible, long-lasting, and lightweight — ideal for optimizing sound in restaurants, offices, hotels, and more.
