Foam Panel Category — 2-Pack “Egg-Crate” Soundproofing Foam Panels; 48 × 24 × 2 inches per piece; High-Density and Fire-Resistant; Black

This 2-pack of large-format foam panels features sheets measuring an impressive 48″ x 24″ x 2″ (4 feet by 2 feet) each. A single panel covers 8 square feet, providing a total coverage area of ​​16 square feet for the pair. Constructed from high-density (28 kg/m³) flame-retardant polyurethane foam, the surface features an “egg-crate” (convoluted) pattern. This high density provides superior sound-damping capabilities, offering absorption performance—particularly in the low-frequency range (200 Hz–500 Hz)—that exceeds that of standard-density foams. The fire-retardant rating complies with California TB 117 standards, ensuring the material is self-extinguishing once removed from a flame source. Featuring a sleek black finish, this product is ideal for large-scale wall treatment applications in professional recording studios, small home theaters, or music classrooms. The two-piece package can be installed side-by-side to create a 4×4-foot square sound-absorbing zone, or installed separately at the left and right “first reflection points.” Installation Tip: As the foam panels are relatively heavy (approximately 1.5 kg each), we recommend using a heavy-duty spray adhesive, or supplementing with double-sided tape and a staple gun for added security. A positioning grid sheet is included with the product to assist you in evenly spacing your mounting points.
