Advanced Acoustics Tri-Panel Acoustic Studio Foam Tiles

The Advanced Acoustics Tri-Panel 24" is a 55mm open-cell polyurethane acoustic foam tile in a precision CNC-cut triangular format, measuring 610mm × 610mm (24" × 24"). The tile achieves NRC 0.95 (Sound Absorption Class B), providing high-performance broadband absorption across the mid and high frequency range. Each pack contains 6 tiles, covering 1.11m² (12sqft) of wall or ceiling surface. The triangular format allows tiles to be arranged in clustered or rotational patterns that differ visually from square and rectangular tile installations, making the Tri-Panel suited to feature wall installations where the geometry of the tile is part of the design intent. Absorption: 0.55 at 250Hz, 1.10 at 500Hz, 1.12 at 1kHz, 1.09 at 2kHz, and 1.15 at 4kHz. Available in Mid Grey and Dark Grey. Manufactured in the UK.

Applications

Recording studios and control rooms — broadband treatment with visual feature.
The Tri-Panel 24" at NRC 0.95 provides Class B broadband absorption across the full mid and high frequency range, with strong performance from 500Hz upward — 1.10 at 500Hz through to 1.15 at 4kHz. The 0.55 at 250Hz delivers meaningful low-mid absorption that addresses the lower frequencies of vocals and instruments. The triangular format allows tiles to be clustered at first reflection points in visually distinctive configurations, combining acoustic treatment with a designed wall feature. Use the Coverage Calculator to determine the number of packs required.

Home studios and recording spaces — high-performance feature treatment.
For home studios where Class B broadband performance is required alongside a more distinctive wall finish than standard square tile formats, the Tri-Panel 24" provides NRC 0.95 in a triangular format that can be arranged in rotational, clustered, or alternating patterns. The large 24" tile size covers more wall area per tile than the 12" range, reducing the number of installation pieces required for a given treatment area.

Vocal booths and isolation rooms.
Vocal booths require effective absorption across the vocal frequency range to prevent the tight, coloured sound produced by reflections in a small enclosed space. The Tri-Panel 24" provides strong absorption from 500Hz through to 4kHz, covering the fundamental frequencies and harmonics most critical for vocal recording. The triangular format suits vocal booth installations where a more refined visual finish than standard wedge or pyramid foam is preferred.

Product Benefits

NRC 0.95 / Sound Absorption Class B — high-performance broadband absorption.
The 55mm foam core achieves NRC 0.95 (Class B), with absorption of 0.55 at 250Hz, 1.10 at 500Hz, 1.12 at 1000Hz, 1.09 at 2000Hz, and 1.15 at 4000Hz. The performance profile matches the Tegular 12" and Baby HexaTile 12" at the same NRC and depth, with the triangular format providing a different visual result. For maximum low-frequency absorption within a large-format tile, the Tegular 15" range in 3" or 4" depths provides Class A performance at greater foam depths.

Triangular format — clustered and rotational layout options.
The CNC-cut triangular format allows tiles to be arranged in clustered, rotational, or alternating patterns that create visually distinctive wall installations. The 24" tile size provides a large-format surface area per tile, suited to feature wall installations where the geometry of the tile contributes to the room design. Triangular tiles can be combined with square 12" tiles from the Advanced Acoustics range to create mixed-format wall treatments.

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 610mm × 610mm × 55mm (24" × 24" × 2 3/8"). 6 tiles per pack, 1.11m² (12sqft) 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.

Notes: For Control Rooms it is vital that the wall that has the control desk placed on it is entered as the Room Width even if this is the longest wall. Available Corners refers to the amount of wall to wall corners that are available for bass traps. There must be at least 350mm of free space on either wall for it to qualify.

Installing our acoustic foam tiles is very simple. The first step to take is to work out your preferred layout of acoustic tiles. Do a sketch on paper first to make sure that the layout looks right and you have enough acoustic foam and space for your planned design. It is best to have small to medium sized clusters of acoustic foam tiles evenly distributed as opposed to one huge cluster of tiles in the middle of a wall.

Once the acoustic tiles are mounted to the wall or ceiling they are hard to remove so it is important to get the layout right before you begin. Once you have a sketch of the layout you plan you can then mark up the wall with the layout. You can either use pencil, masking tape or lasers to layout the design on the wall or ceiling.

When mounting the acoustic tiles to the wall apply Advanced Acoustics Contact Adhesive to both the back of the tile and the mounting surface. There is no need to heavily cover the acoustic foam or wall with adhesive, a band of adhesive around the perimeter of the tile along with 50% - 75% coverage of the rest of the tile will be fine. Use the same equivalent amount on the wall. Avoid overspray on the tile and the wall so that adhesive can’t be seen when the tiles are in place. Masking Tape on the wall will help with this. If you do get webbing overspray on the tile, don’t touch it, allow it to dry, in most cases you will be able to peel the adhesive off.

The adhesive we supply is solvent based so we recommend that you keep all doors of the room and any windows open whilst completing the installation.

If you prefer to have a more temporary installation of acoustic tiles you can mount the tiles onto 6mm MDF or ply to create panels of acoustic tiles. These panels can then be hung on the wall using a D-Ring and picture hook for a damage free installation. If fitting them to a ceiling then 4 mirror plates would be required.
