All acoustic board is NOT created equal. MAXSORB™ panels use a 6 PCF high-density rigid fiberglass core for superior sound absorption and higher NRC performance than lower-density options. Available in 1″ (NRC 0.85) and 2″ (NRC 1.15) thicknesses, MAXSORB™ unwrapped acoustic panels deliver reliable sound absorption for a wide range of commercial and industrial applications. The increased density improves acoustic performance across frequencies for clearer, quieter spaces.

Raw Board Flexibility

These unwrapped panels give you full versatility for commercial, industrial and DIY applications:

Install as-is for a cost-effective noise reduction solution
Use behind walls, above ceilings, or inside enclosures
Create your own DIY panels with Guilford of Maine Anchorage, FR701, Whisper or miscellaneous acoustic fabrics

Key Benefits

High sound absorption reduces echo and reverberation
Improved clarity and comfort in commercial and industrial spaces
Class A fire-rated for safety

Ideal Applications

Open offices, restaurants, manufacturing spaces, studios, and above-ceiling or behind-wall treatments, plus DIY acoustic panel projects.

Frequently Asked Questions View All FAQs

Our products are safe and effective and have been tested by an independent lab. All our panels and clouds carry a Class A fire rating which is the highest rating possible under the ASTM E84, a test used by code officials and regulatory agencies in the acceptance of interior finish materials.

We offer our panels, clouds and panel kits in 1 and 2 inch thicknesses.

A 1 inch thickness is ideal for residential spaces with minimal people.
A 2 inch thickness is suited to commercial spaces such as restaurants, offices, houses of worship and auditoriums. A 2 Inch thickness is also ideal for maximum absorption per square foot of space.

If you are unsure of how many panels / or clouds are recommended you can fill out our inquiry form.
