3" Class 0 Acoustic Foam Panel - 2ft by 4ft
The Advanced Acoustics Class '0' 3" is a 75mm acoustic foam panel manufactured from 90kg/m³ open-cell foam, measuring 2ft × 4ft (610mm × 1220mm). The panel achieves NRC 0.90 (Sound Absorption Class A) — the highest acoustic rating in the Class '0' range — providing comprehensive broadband absorption with strong low-frequency performance. Each panel covers 0.74m² (8sqft).
The panel carries the same Class '0' fire classification as the 1" and 2" versions — meeting BS 476 Parts 6 and 7, C s1, d0 to EN 13501-1, UL94 V-0, and Class A to ASTM E84-95 — and is the appropriate specification where Class '0' compliance is required alongside the highest available acoustic performance. Absorption: 0.73 at 250Hz, 0.92 at 500Hz, 0.90 at 1kHz, 0.99 at 2kHz, and 1.03 at 4kHz. Available unmounted or mounted to a 6mm MDF substrate. Available in Black. Manufactured in the UK.
Applications
Public buildings and commercial premises — Class '0' compliance at maximum performance.
Where Class '0' compliance is required and the acoustic treatment demands the highest available performance, the 3" panel is the appropriate specification. The NRC 0.90 and Class A rating deliver comprehensive broadband absorption across the full mid and high frequency range, and the 0.73 at 250Hz provides strong low-frequency treatment that the 1" (0.22) and 2" (0.44) panels cannot match. Suited to large open-plan commercial spaces, auditoria, conference facilities, and educational environments where both regulatory compliance and thorough acoustic control are required. Use the Coverage Calculator to determine the number of panels required.
Professional studios and broadcast facilities — Class '0' with Class A performance.
Recording studios and broadcast facilities operating under commercial Class '0' surface lining requirements can specify the 3" panel where comprehensive broadband treatment is needed. The 0.92 at 500Hz and consistent performance through 1kHz, 2kHz, and 4kHz delivers absorption across the full recording frequency range, while the 0.73 at 250Hz addresses the low-mid reverberation that the thinner Class '0' panels leave partially uncorrected. The Class A rating makes this the highest-performing specification option within the Class '0' panel range.
Custom Class '0' fabric-wrapped panels — highest performance specification.
The unmounted 3" Class '0' panel is the appropriate base for fabric-wrapped acoustic panels in commercial and public spaces where the highest available Class '0' compliant performance is required. The 75mm, 90kg/m³ foam core delivers NRC 0.90 behind an acoustically transparent open-weave fabric, making it the premium specification for compliant fabric panel installations in professional and commercial environments. Custom sizes are available on request.
Product Benefits
NRC 0.90 / Sound Absorption Class A — maximum performance in the Class '0' range.
The 75mm foam core achieves NRC 0.90 (Class A), with absorption of 0.73 at 250Hz, 0.92 at 500Hz, 0.90 at 1000Hz, 0.99 at 2000Hz, and 1.03 at 4000Hz. This is the highest acoustic performance available within the Class '0' panel range, with the 0.73 at 250Hz providing substantially stronger low-frequency absorption than the 2" panel (0.44) and the 1" panel (0.22). As with all Class '0' panels, the NRC is lower than a standard polyurethane Acousti-Slab at equivalent depth due to the acoustic characteristics of the 90kg/m³ foam required for Class '0' compliance.
Class '0' fire classification — compliant with UK Building Regulations.
Fire Propagation Index less than 12 (BS 476 Part 6); Surface Spread of Flame Class 1 (BS 476 Part 7); Class '0' to Building Regulations 1991 (BS 476 Parts 6 and 7); C s1, d0 (EN 13501-1); UL94 V-0; Surface Burning Class A (ASTM E84-95). Suitable for use in public and commercial buildings where surface linings must comply with Class '0' under UK Building Regulations.
Unmounted and mounted-to-MDF formats.
The unmounted panel is bare foam suitable for direct adhesive fixing or trimming to size. The mounted panel is pre-fixed to a 6mm MDF substrate for wall hanging using mirror plates. Both formats are available in Black only.
Specification and compliance.
90kg/m³ foam density. Class '0' to BS 476 Parts 6 and 7; C s1, d0 to EN 13501-1. Panel size 610mm × 1220mm × 75mm (2ft × 4ft × 3"). 0.74m² (8sqft) coverage per panel. 4.2kg unmounted, 7.8kg mounted. Black. Custom sizes available on request. Manufactured in the UK and shipped uncompressed from stock.
Installation
Unmounted panels — adhesive fixing.
Apply Advanced Acoustics High Strength Contact Adhesive to both the back of the panel and the wall surface. Apply a band of adhesive around the perimeter and 50–75% coverage of the remaining surface area; repeat on the wall. Allow to become touch-dry before bringing surfaces together — contact adhesive bonds on contact, so position the panel carefully before pressing it to the wall. The adhesive is solvent-based; ensure adequate ventilation throughout installation.
Unmounted panels — demountable installation.
For a temporary or demountable installation, mount the panel onto 6mm MDF or plywood sheet and hang using D-rings and picture hooks. For ceiling-mounted panels, use four mirror plates per panel. This allows panels to be removed and repositioned without damage to the wall surface.
Mounted-to-MDF panels.
Fix mirror plates to the wall at the appropriate centres using suitable fixings for the wall substrate. Hang the panel on the mirror plates. The mounted panel can be removed and rehung without tools.
