AcoustiFelt Fabric Acoustic Shapes

Acoustic Shapes provide excellent acoustic absorption to improve quality sound in a space. They are a healthy and visually appealing sound solution compared to traditional foam and fiberglass alternatives. Each shape is created with our proprietary eco-C-tex® sound absorption material and is fabric faced with Felt fabric from Guilford of Maine.

Please Note: Only the top surface of the planks have fabric and the sides are exposed eco-C-tex. Due to eco-C-tex consisting of recycled materials, natural variations in texture and shading can occur, especially from order to order.

Choose from 16 shapes in two pack sizes (small and large), and three thicknesses (0.5", 1", and 1.5").

  • Made in the USA
  • Eco-Friendly

Acoustic Product Installation Easy Installation - AcoustiColor Planks are designed to be mounted to a surface using Audimute Strata® Tape along with Loctite® Power Grab® Express Heavy Duty, or using a brad nailer such as a Paslode® Brad Nailer and our Compatible Foot. Other installation methods can be used, such as industrial foam tape, however, we have not tested other methods and therefore cannot guarantee their effectiveness and are not responsible for installation failures.
