Advanced Acoustics 15" x 15" 4" Tegular Acoustic Studio Foam Tile Pack
The Advanced Acoustics Tegular 4" is a 100mm open-cell polyurethane acoustic foam tile with a plain face and 45-degree bevel cut on all four sides, measuring 381mm × 381mm (15" × 15"). The tile achieves NRC 1.05 (Sound Absorption Class A) — the deepest and highest-performing tile in the Tegular 15" range. Each pack contains 24 tiles, covering 3.48m² (37.5sqft) of wall or ceiling surface.
Absorption: 0.85 at 250Hz, 1.09 at 500Hz, 1.11 at 1kHz, 1.14 at 2kHz, and 1.13 at 4kHz. NRC values above 1.00 occur in standardised reverberation chamber testing as a result of edge diffraction effects, a recognised characteristic of deep absorbers tested under ISO 354 conditions. The 0.85 at 250Hz delivers the strongest low-frequency absorption in the Tegular 15" range. Available in Mid Grey and Dark Grey. Manufactured in the UK.
Applications
Professional recording studios and control rooms — maximum broadband treatment.
The Tegular 4" at NRC 1.05 (Class A) provides the most comprehensive broadband absorption available in the Tegular 15" range, with the 0.85 at 250Hz delivering strong low-frequency performance that addresses the full frequency range of vocals, instruments, and monitoring. Suited to professional studios and control rooms where the most thorough available treatment within a flat-face tile format is required. The large 15" format and 3.48m² coverage per pack suit the wall surfaces of professional studio environments. Use the Coverage Calculator to determine the number of packs required.
Rehearsal rooms and live rooms — deep low-frequency control.
The 100mm depth delivers the strongest low-frequency absorption in the Tegular 15" range, addressing the low-mid frequency energy that contributes to muddiness in musical performance. The Tegular 4" is the appropriate specification where deep broadband treatment including strong low-frequency control is required across the larger wall areas of rehearsal and live room environments.
Distributed low-frequency treatment.
While dedicated bass traps in room corners remain the most efficient approach to low-frequency room mode control, the Tegular 4" provides a level of distributed low-frequency absorption — 0.85 at 250Hz — that complements corner bass trap installations. The 100mm depth begins to address frequencies in the 250Hz range across wall surfaces, useful in environments where thorough low-frequency treatment is required alongside mid and high frequency control.
Product Benefits
NRC 1.05 / Sound Absorption Class A — maximum performance in the Tegular 15" range.
The 100mm Tegular foam core achieves NRC 1.05 (Class A), with absorption of 0.85 at 250Hz, 1.09 at 500Hz, 1.11 at 1000Hz, 1.14 at 2000Hz, and 1.13 at 4000Hz. The 0.85 at 250Hz is the strongest low-frequency result in the Tegular 15" range, delivering meaningful absorption at a frequency where shallower tiles perform less effectively. The 4" is the deepest and highest-performing specification in the Tegular 15" range.
Tegular profile — flat face with bevel cut, minimal aesthetic.
The Tegular profile — a flat face with a 45-degree bevel cut on all four sides — produces a clean, grid-like pattern when tiles are installed edge to edge. The bevel forms a defined joint line between tiles, giving the installation a finished, architectural appearance suited to professional environments where a minimal aesthetic is preferred.
Specification and compliance.
30kg/m³ foam density. Crib 5 and Schedule 1, Part 1 of the Furnishings and Furniture (Fire)(Safety) Regulations 1988 (amended 1989). Tile size 381mm × 381mm × 100mm (15" × 15" × 4"). 24 tiles per pack, 3.48m² (37.5sqft) coverage. Mid Grey and Dark Grey. Manufactured in the UK and shipped uncompressed from stock.
Installation
Plan the tile layout before beginning installation. Sketch the intended pattern on paper and mark the layout on the wall or ceiling surface using pencil, masking tape, or a laser level. Distribute tiles evenly across the treatment area rather than concentrating them in a single large cluster; even distribution provides more consistent absorption coverage across the room.
Apply Advanced Acoustics Contact Adhesive to both the back of the tile and the mounting surface. Apply a band of adhesive around the perimeter of the tile and 50–75% coverage of the remaining surface area; repeat the equivalent coverage on the wall. Allow the adhesive to become touch-dry before bringing the surfaces together — contact adhesive bonds on contact, so position the tile carefully before pressing it to the wall. Avoid overspray onto the tile face or surrounding wall surface; use masking tape on the wall to protect adjacent areas. If adhesive webbing contacts the tile face, allow it to dry fully before attempting to remove it — in most cases it can be peeled away cleanly once dry. The adhesive is solvent-based. Ensure adequate ventilation throughout the installation — keep doors and windows open.
For a temporary or demountable installation, mount tiles onto 6mm MDF or plywood sheet to create panels, then hang the panels using D-rings and picture hooks. For ceiling-mounted panels, use four mirror plates per panel. This approach allows panels to be removed and repositioned without damage to the wall or ceiling surface.
