Two charcoal foam panels, each 48 by 96 inches, 2 inches thick

Auralex

Auralex Sonomatt Acoustic Panel 2 in × 48 in × 96 in Charcoal 2 Pack

SKU CH-TGJS-K8MQE

Two 2-inch thick foam panels cover 64 sq ft with a 0.7 NRC and meet CAL 117 and ASTM-D3574 Rev 12-3 flammability standards

  • ColorGray
  • 7 NRC rating reduces echo across large rooms
  • Two-inch foam thickness absorbs mid-to-high frequencies
  • 64 sq ft total coverage from two panels
  • CAL 117 and ASTM D3574 compliance meets fire codes
  • Charcoal finish blends into studio or office ceilings

Two-Pack Coverage for Large Surfaces

Two charcoal panels each measure two inches thick by forty-eight inches wide by ninety-six inches long, providing sixty-four square feet of total coverage. The foam construction targets mid-to-high frequency reflections in studios, broadcast rooms and home theatres. Installation is straightforward on walls or ceilings using adhesive or mechanical fasteners.

Upgrade from Thinner Foam Tiles

Replacing one-inch or half-inch tiles with this two-inch thickness raises the noise reduction coefficient to point seven, absorbing more low-mid energy that thinner material misses. The improvement is most noticeable when treating large parallel walls or ceiling clouds where modal buildup occurs. Rooms already treated with two-inch panels will hear little additional benefit.

Consistent Absorption Under Continuous Use

The foam meets CAL 117 and ASTM-D3574 Rev 12-3 flammability standards, so performance remains stable during extended sessions without degradation or safety concerns. Rigid cell structure resists compression from repeated handling or permanent mounting. Charcoal colour hides dust and lighting-hot spots, keeping the treatment looking neutral over time.

Questions about this item

What thickness and panel dimensions do I need to accommodate for the two panels?

Each panel measures 2 in thick by 48 in wide by 96 in long, giving a total of 64 sq ft of coverage for the pair.

How are the foam panels mounted, and what common step is missed?

They are typically adhered with construction adhesive or mechanical fasteners to a clean, dry substrate; the step often missed is allowing the adhesive to fully cure before exposing the panels to stress.

What fire-performance standards do the panels meet for future inspection or replacement planning?

The foam complies with CAL 117 and ASTM-D3574 Rev 1, 12-3, so any replacement should carry the same ratings to maintain code compliance.
