Choosing between wood slat and PET felt acoustic panels comes down to more than appearance. While both are designed to improve acoustic comfort by reducing echo and softening harsh sound reflections, they take very different approaches in terms of design, performance, flexibility, and overall application. At Barron Designs, our acoustic panel collection includes two distinct solutions: AcousticMod Slat Wood Acoustic Wall Panels, which combine natural wood aesthetics with acoustic backing for a warm, architectural look, and FSorb Acoustic Panels, which offer lightweight PET felt construction with expanded design flexibility and strong standalone sound absorption.
Whether you're designing a cozy home office, inspiring podcast studio, memorable restaurant, focus-enhancing conference room, or larger commercial space, the best acoustic panel solution depends on how you want the room to both sound and feel. Some spaces benefit from acoustic treatment that doubles as a striking architectural feature, while others need flexible layouts, bold color options, or more performance-driven sound absorption. Below, we’ll compare AcousticMod and FSorb panels across materials, style, acoustic performance, pricing, customization, fire ratings, and eco-friendliness.
Comparing Materials: Decorative Wood Slats vs. Recycled PET Felt
AcousticMod Panels in Walnut
AcousticMod Slat Wood Acoustic Wall Panels are made with PVC-coated MDF slats over a sound-absorbing felt backing. This construction gives the panels both decorative dimension and acoustic function, making them a strong choice when the wall treatment needs to contribute to the overall design.
So, what are PET felt acoustic panels? FSorb’s PET acoustic panels are made from thermally bonded recycled polyester plastics and contain no adhesives, paints, coatings, VOCs, formaldehyde, itchy particles, wood, agricultural, or paper products. Because they’re available in a wide variety of colors, they’re a great choice for when you want to move beyond a wood look while still improving the acoustic quality of an interior space.
Style Comparison: Warm Wood Texture vs. Bold Modern Flexibility
FSorb Silentline Ceiling Baffles Panels in Light Beige, Sky Blue, Ocean Blue, and Midnight Navy
AcousticMod panels create a clean-lined wood slat look that feels right at home in modern, organic modern, Scandinavian-inspired, and warm minimalist spaces. They work especially well in home offices, media rooms, podcast studios, reception areas, hospitality interiors, and feature wall applications where the design calls for a modern yet natural look.
The vertical slat profile adds warmth, texture, and architectural rhythm without overwhelming the room. Instead of looking purely functional, the panels feel like a thoughtful part of the overall design.
On the other hand, FSorb panels offer a smooth, uniform PET felt appearance and dynamic color flexibility. Depending on the application, FSorb panels can either blend quietly into offices, schools, gyms, restaurants, retail spaces, and commercial interiors—or become a standout design feature through color blocking, geometric layouts, branded installations, and custom-cut inlays.
Acoustic Treatment Performance
AcousticMod panels on their own have a 0.45 NRC rating, which means they offer minimal sound absorption and more sound reflection than absorption. However, by following Method 3 of the slat wood acoustic panel installation guidelines and installing over mineral wool insulation and timber battens that provide an air gap, AcousticMOD panels can achieve a Class A sound rating, which is the highest rating possible, capable of absorbing 90% to 100% of sound.
FSorb’s sound treatment performance depends on panel thickness.
- 1/2-inch FSorb panels have an NRC rating of 0.50, which is a Class D sound absorption rating
- 1-inch FSorb panels have an NRC rating of 0.70, which is a Class C sound absorption rating
- 2-inch FSorb panels have an NRC rating of 1.05, which is a Class A sound absorption rating
Cost Comparison
FSorb Panels in Dark Green
AcousticMod panels come in 2-panel boxes covering 16.58 square feet. Current pricing varies by finish. with Oak, Teak, Maple, and Walnut listed at $224 per box and Natural MDF Slat Wood Acoustic Wall Panels listed at $264 per box.
FSorb pricing is based on thickness:
- 1/2-inch FSorb panels are listed at $9.04 per 48” x 96” sheet, with a minimum order of 100 sheets
- 1-inch FSorb panels start at $9.75 per 48” x 96” sheet, with a minimum order of 80 sheets
- 2-inch FSorb panels start at $13.04 per 48” x 96” sheet, with a minimum order of 39 sheets
From a pure cost-per-square-foot perspective, FSorb panels are significantly more economical—especially for larger commercial environments that require broad acoustic coverage. AcousticMod panels, meanwhile, carry a higher price point because they function as both acoustic treatment and a finished architectural design feature.
Customizability
AcousticMod panels can be cut on-site to fit around outlets, corners, and other installation obstacles. They are available in several premium wood-look finishes, while the Natural option is ready for paint, stain, or other custom finishes.
FSorb offers even broader customization potential. These panels are available in multiple colors, can be cut on-site, and can be ordered in custom sizes with applicable order minimums. That flexibility makes FSorb a particularly strong choice for branded interiors, educational spaces, creative office environments, hospitality projects, colorful commercial interiors, and geometric acoustic wall layouts.
Fire Rating
Fire ratings can play an important role in commercial, hospitality, educational, and other public-facing environments. AcousticMod panels have a Fire Reaction Class B-S1, d0 rating, a European classification indicating strong performance with limited flame spread, smoke production, and flaming droplets. FSorb acoustic panels offer a Class A fire rating, a North American classification associated with extremely low flame spread characteristics.
For projects with stricter commercial fire-rating requirements, FSorb panels may offer additional flexibility depending on local code requirements and installation methods.
Eco-Friendliness
Both acoustic panel systems offer eco-conscious advantages. AcousticMod panels include FSC Certified wood and a 100% polyester felt backing using 50% recycled PET. FSorb panels are made from recycled PET polyester, feature 0.0 VOC content, and are recyclable.
If sustainability and indoor air quality are priorities for your project, both product lines offer compelling benefits depending on your design goals and preferred aesthetic.
