Frequently Asked Questions

Felt Right tiles are premium, sound-absorbing wall panels made from high-density engineered PET felt. Designed with both acoustic performance and modern design in mind, each tile features a soft, wool-like texture and crisp, chamfered edges for a clean, dimensional finish. At 9mm (3/8 inch) thick, these acoustic tiles are durable, attractive, and easy to install.

Made in the USA, every Felt Right tile is composed of approximately 50% recycled plastic — primarily single-use water bottles — broken down and sterilized without harmful chemicals. The fibers are dyed, felted, and precision-cut into a variety of sizes and shapes to support creative wall treatments for homes, offices, classrooms, and commercial interiors.

Key Features of Felt Right Wall Tiles:

  • Material: 100% PET felt (minimum 50% recycled content)
  • Thickness: Standard 9mm (⅜ inch); 18mm available for custom orders
  • Finish: Chamfered edges for a seamless, dimensional look
  • Sound Absorption: NRC rating of 0.35 (absorbs ~35% of ambient sound)
  • Eco-Friendly: Helps divert plastic waste from landfills
  • Applications: Ideal for acoustic panels, pin boards, creative walls, and design accents

Yes! Felt Right tiles can be trimmed to any size using a razor blade and a straight edge (see example here). For the cleanest results, cutting along the engraved pattern lines is easiest, but any custom dimension works fine. For more control or complex shapes, we recommend:

  • A serrated utility knife for general cuts
  • Standard woodworking tools or a jigsaw for straight edges and angles
  • A plywood template and a router with a flush-cut pattern bit for curves

Felt Right tiles have a Noise Reduction Coefficient (NRC) of 0.35, meaning they absorb approximately 35% of the sound that hits them. When installed across a significant portion of your wall, they can greatly reduce echo, soften harsh acoustics, and create a more comfortable listening environment.

For even greater sound absorption, Felt Right also offers a range of high-performance acoustic solutions beyond wall tiles. Our ceiling baffles come in three styles, each with a Noise Reduction Coefficient (NRC) ranging from 0.65 to 0.80. For maximum acoustic performance, our Wood Slat Ceiling Panels deliver an impressive NRC of 0.85. We also offer Wood Slat Wall Panels, which combine aesthetic warmth with sound control, and feature an NRC of 0.55.

Felt Right tiles are designed to be low-maintenance and easy to clean.

Routine Cleaning:

  • Use a vacuum hose attachment to remove dust and lint
  • A lint roller can also work for quick surface touch-ups

Spot Cleaning:

  • Wipe with a damp cloth
  • For more stubborn marks, spray with a common household cleaner and gently wipe down
  • Avoid oversaturation to preserve the felt's integrity

Disinfection (Commercial Environments):

  • Tiles can be disinfected using multi-surface cleaning sprays or non-abrasive disinfectant wipes
  • Ideal for schools, offices, and shared workspaces

Felt Right adhesive tabs are conformable and will adhere to most surfaces, including textured walls. We recommend switching to our Commercial Grade adhesives at checkout for heavy textures like brick, cement, and cinderblock. We also recommend adding construction adhesive for secure bonding if needed.

Use our Felt Right Design Studio to create and preview your own custom wall layout. This easy-to-use tool lets you:

  • Choose from all available tile shapes and colors
  • Visualize your design in real-time
  • Adjust for wall dimensions and room size
  • Add patterns, borders, graphics, or full-wall applications

Once you're happy with your design, you can save, share, or order directly from the tool. If you'd like help customizing tile dimensions, shapes, or colors — or want expert advice to create the best design for your space — feel free to email us at design@feltright.com. Our team would love to help!
