12" F.A.T. Acoustic Foam Tile Pack
The Advanced Acoustics F.A.T. 12" is a 40mm open-cell polyurethane acoustic foam tile in a precision CNC-cut egg-crate profile, measuring 305 × 305mm. F.A.T. stands for Fundamental Acoustic Treatment — the egg-crate profile is one of the original and most widely recognised acoustic foam formats, characterised by the alternating peak-and-valley surface that gives the tile its distinctive appearance. The tile achieves NRC 0.55 (Sound Absorption Class D), providing effective absorption across the mid and high frequency range. Each pack contains 24 tiles, covering 2.23m² (24ft²) of wall or ceiling surface. Absorption increases with frequency: 0.21 at 250Hz, 0.46 at 500Hz, 0.66 at 1kHz, 0.80 at 2kHz, and 1.08 at 4kHz. Available in Mid Grey. Manufactured in the UK.
Applications
Podcast studios and broadcast environments — high-frequency echo control.
Podcast and broadcast studios require effective control of high-frequency reflections and flutter echo to produce clean, clear microphone recordings. The F.A.T. 12" provides effective absorption from 1kHz upward — 0.66 at 1kHz, 0.80 at 2kHz, 1.08 at 4kHz — targeting the frequency range most responsible for the reflective quality of untreated rooms. The large 2.23m² coverage per pack makes it efficient to treat the wall areas behind and beside the recording position. Use the Coverage Calculator tab to determine the number of packs required.
Vocal booths and isolation rooms.
Vocal booths require effective high-frequency absorption to prevent the tight, boxy sound caused by excessive reflections in a small enclosed space. The F.A.T. 12" provides effective absorption at the frequencies most critical for vocal recording — 1kHz and above — reducing the coloration introduced by room reflections and producing a cleaner vocal capture. The 40mm profile is suited to vocal booths where wall space is limited and a thinner tile is preferred to maximise usable room volume.
Home studios and recording spaces — entry-level acoustic treatment.
For home studios where the primary acoustic problem is high-frequency flutter echo and reverberation, the F.A.T. 12" provides effective entry-level treatment in the classic egg-crate format. The profile is the original acoustic foam tile shape — widely used in professional studios for decades — and remains an effective and cost-efficient option for home recording environments. Install on the primary reflection points — side walls, rear wall, and ceiling — to achieve even absorption coverage throughout the room.
Rehearsal rooms and live rooms — high-frequency control.
Rehearsal rooms benefit from controlled high-frequency reverberation to reduce the build-up of reflected sound energy that makes it difficult for musicians to hear each other clearly. The F.A.T. 12" provides effective absorption at the higher frequencies most responsible for this build-up. The large coverage per pack makes it efficient to treat the wall areas of a rehearsal room at a lower cost per m² than thicker profiles.
Mixing and mastering rooms — supplementary high-frequency treatment.
In mixing and mastering environments where low-frequency room treatment is already addressed by bass traps, the F.A.T. 12" can be used to supplement high-frequency absorption on wall and ceiling surfaces. The absorption above 1kHz reduces the influence of high-frequency reflections on the monitoring position without the additional cost of thicker tiles where low-frequency absorption is not the primary requirement.
Product Benefits
NRC 0.55 / Sound Absorption Class D — effective high-frequency absorption.
The 40mm egg-crate foam core achieves NRC 0.55 (Class D), with absorption increasing with frequency: 0.21 at 250Hz, 0.46 at 500Hz, 0.66 at 1000Hz, 0.80 at 2000Hz, and 1.08 at 4000Hz. The egg-crate profile achieves a slightly lower NRC than wedge profiles at the same nominal thickness — the void space between peaks means the average effective depth across the tile face is less than the 40mm peak measurement, which accounts for the difference in absorption performance relative to a continuous wedge cut of the same height.
Egg-crate profile — classic F.A.T. format, precision cut for consistent dimensions.
The egg-crate profile — peaks and valleys alternating across the tile face — is the original acoustic foam tile format and one of the most recognisable shapes in studio acoustic treatment. Each tile is cut using precision machinery to ensure consistent peak height and valley depth across every tile in the pack, producing a uniform appearance across the installed surface.
High-density polyurethane foam — 30kg/m³, fire rated.
The foam core is manufactured at 30kg/m³ density, providing greater structural integrity and longer service life than lower-density acoustic foam. Higher density foam maintains its shape and acoustic performance over time without the compression and degradation that affects lower-density products. The foam meets Crib 5 and Schedule 1, Part 1 of the Furnishings and Furniture (Fire)(Safety) Regulations 1988 (amended 1989).
24 tiles per pack — 2.23m² coverage.
Each pack contains 24 tiles at 305 × 305mm, providing 2.23m² (24ft²) of coverage. Use the Coverage Calculator tab to determine the number of packs required for your room dimensions and room type before ordering.
Available in Mid Grey.
The F.A.T. 12" is available in Mid Grey. Shipped uncompressed from stock to maintain tile integrity in transit.
Made in the UK — shipped uncompressed.
All F.A.T. 12" packs are manufactured in the Advanced Acoustics UK facility and shipped uncompressed, ensuring tiles arrive in full-dimension condition ready for installation.
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.
