Acoustic Felt Panels vs Foam Panels: What Should You Buy?

Felt or Foam: The Short Answer

Open-plan offices, meeting rooms, classrooms and home studios all suffer from the same problem: noise bounces off hard walls and turns speech into clutter. Two products dominate the fix — acoustic felt panels and acoustic foam panels. They look similar in photos but behave very differently in a real project. This guide compares acoustic felt panels against acoustic foam panels on sound absorption, fire safety, durability, looks and cost, so specifiers and buyers can choose the right soundproof wall panels the first time.

What Are Acoustic Felt Panels?

Acoustic felt panels are made from compressed PET felt, a dense polyester fibre board with a soft textile finish. The material absorbs sound across a wide frequency range, which makes it effective for both speech clarity in offices and music treatment in studios. Beyond acoustics, felt panels offer real advantages for commercial projects: they are impact-resistant, easy to clean, available in fire-rated versions, and can be made from recycled PET. They mount flush on walls and come in square tiles, slats and custom shapes that look like intentional interior design rather than acoustic treatment.

• Compressed PET felt: dense, soft-textured, dimensionally stable
• Broadband sound absorption — good for speech and music
• Fire-rated and recycled-content options available
• Impact-resistant, cleanable, designer-friendly finishes

What Are Acoustic Foam Panels?

Acoustic foam panels are open-cell polyurethane or melamine foam shaped with wedges or pyramids. They are light, inexpensive and effective at absorbing mid and high frequencies, which is why they are the classic choice for home studios treating vocals and instruments. However, foam has limits in commercial settings. Standard acoustic foam is flammable unless specially treated, degrades under UV light, and low-density melamine foam crumbles at the edges over time. Its visual language is also strongly "studio", which rarely suits offices, hotels or education spaces.

• Lightweight open-cell foam, wedge or pyramid profile
• Good mid/high-frequency absorption at low cost
• Fire risk and UV ageing unless specially treated
• Can crumble or yellow in demanding environments

Felt vs Foam: Key Differences at a Glance

Which Soundproof Wall Panels for Which Space?

Match the product to the risk profile of the room. For offices, classrooms, reception areas and hotels, acoustic felt panels are the responsible specification: they deliver broadband absorption, pass stricter fire checks and keep looking professional for years. For a private home studio on a tight budget where only vocals need taming, acoustic foam panels can still do an acceptable job. Where you need both durability and a premium finish — conference rooms, restaurants, gyms — felt panels are the better long-term investment.

• Open-plan office / meeting room: felt panels
• Home studio voice treatment: foam (budget) or felt (balanced)
• School, kindergarten, hotel: felt with fire rating
• Restaurant or gym ceiling and wall: felt

Installation, Maintenance and Cost in Practice

Acoustic foam panels are usually glued directly to the wall with spray adhesive; they are quick to fit but hard to clean once dusty. Acoustic felt panels can be installed with adhesive mounting pads, mechanical clips or framed systems, which makes removal and reconfiguration easier in rented or phased projects. Cleaning is simple — dusting or light vacuuming keeps the felt surface fresh. On whole-life cost, foam appears cheaper per sheet, but replacement cycles and fire-compliance upgrades in commercial projects regularly erase that gap. For a professional result that lasts, felt panels usually win the total-cost comparison.

Buying Checklist for Soundproof Wall Panels

• Confirm the fire rating required for your market and building type
• Ask the supplier for the absorption test data, not just marketing claims
• Check whether the soundproof wall panels are made from recycled material
• Request samples of both acoustic felt panels and foam and compare in situ
• Compare the installed cost per square metre of soundproof wall panels, including mounting and edges
