Acoustic GRG

What Acoustic GRG does

Acoustic GRG Ltd is a privately held, family-run UK manufacturer and distributor of acoustic treatment products, headquartered at a single workshop in Folkestone, Kent, founded in 1991 by Brian Moule in partnership with Dr Peter D'Antonio of RPG Diffusor Systems Inc. The company manufactures absorbers, diffusers, reflectors and bass-control products using gypsum (GRG), timber, acrylics, engineered timber and recycled polyester, with over 80% of output produced on-site. Its proprietary catalogue includes patented and licensed RPG technologies (Skyline, Skyline LP, QRD734, Modffusor, Modffractal, BAD Panel family, Waveform series, Abflector VDAC) alongside complementary product lines such as the Broadsorber and High Impact absorber panels, perforated, micro-perforated and slotted panels, and ceiling baffles/clouds/cubes. Acoustic GRG also holds exclusive UK distribution rights for Opus Musician Posture Chairs, Mpod modular acoustic pods (38–56 dB), Spigogroup wooden panels, Clipso stretch fabrics, Biotech TNA acoustic plaster, S.A.C. Silent acoustic plaster, Cewood timber panels, Fret recycled polyester absorbers, and DeAmp fibre-free absorbers.

The company operates a sales-led go-to-market model targeting architects, acousticians, interior designers, main and sub-contractors, cost consultants, AV contractors and home cinema installers, with revenue generated from one-time product sales and ancillary installation services priced on a bespoke contact-quote basis. Customer segments are weighted toward music and recording studios, education facilities (conservatoires, universities, schools), performance venues (concert halls, theatres) and worship spaces, with secondary exposure to commercial offices, hospitality/healthcare and domestic home cinema. Named end-customers include BBC Symphony Orchestra, London Symphony Orchestra, Royal Albert Hall, Queen Elizabeth Hall (Southbank Centre), Birmingham Symphony Hall, Casa da Musica (Portugal), Royal College of Music, Eton College, Birmingham Conservatoire and RAF Northolt, alongside international exports to the USA, Australia, Oman, Costa Rica, Holland and Hong Kong. Mathew Moule has served as Managing Director since 2015, succeeding his father Brian, and in 2026 the company renewed its core manufacturing collaboration with RPG Acoustic.

Products and services

• RPG Diffusor Systems Range Comprehensive range of acoustic absorbers, diffusers, bass control products, ceiling panels, wall panels, slotted planks, and perforated panels manufactured under licence from RPG Diffusor Systems Inc., used by acousticians and contractors to control sound reflections and reverberation in studios, performance venues, and offices.
• Skyline / Skyline LP Diffusers Patented omnidirectional 2D primitive-root diffuser (Skyline) and its low-profile variant (Skyline LP) that scatter incident sound uniformly to minimise acoustic glare, with the LP version designed for installations with limited wall depth.
• QRD734 Diffusor Classic 1D wood sound diffuser based on quadratic residue number theory, providing uniform sound field through mid- and high-frequency diffusion while limiting sound absorption; available in wood veneer, laminates, melamine, and painted finishes at standard 230mm depth.
• Waveform Series Diffusers Patented asymmetric waveform diffuser series (Spline, Monoradial, Biradial, Bicubic, Gaussian) available in GRG or wood constructions, designed to blend direct and reflected sound to increase intelligibility and enhance musical clarity in auditoriums and performance venues.
• Modffusor Diffusor Patented computer-optimised 1D wood sound diffuser with an asymmetric base shape and aperiodic modulation, offering improved scattering performance over QRD734 in a shallower profile; multiple units can be sequence optimised for further improvement.

Direct peers

• RPG Diffusor Systems Inc. US pioneer of acoustic diffusion and absorber technology that co-founded Acoustic GRG in 1991 and whose patented diffuser IP (QRD, Skyline, Waveform, Modffusor, BAD) Acoustic GRG manufactures and distributes in the UK and Europe. Strongest direct peer given shared product family and intertwined ownership of the technology roadmap.
• Spigogroup: Spanish manufacturer of acoustic wooden panels, perforated slats, and acoustic doors, distributed in the UK by Acoustic GRG. Direct peer in both acoustic panels and architectural wood-product categories, primarily competing in UK and European commercial projects.
• Gustafs Scandinavia: Swedish manufacturer of architectural acoustic panels and ribbed wood systems for halls, auditoria, and public venues. Highly comparable in terms of premium specification projects, performance-venue focus, and large-panel ribbed diffuser formats, although typically at larger scale and broader design-brand profile.
• BAUX: Swedish designer and manufacturer of acoustic wood-wool and pulp panels targeted at commercial offices, education, and music spaces. Direct comparable on product format (acoustic panels), material sourcing (sustainable wood/wool), and specifier-driven sales motion, with stronger brand presence in architecture and design media.
• Carnegie Fabrics: US-based manufacturer of acoustic textile panels (Xorel, Acoustical Wall Solutions) targeting commercial, education, and healthcare projects. Comparable in fabric-wrapped acoustic wall panels and in targeting A&D/specifier channels, primarily serving the North American market.
• Texaa: French manufacturer of fabric-wrapped acoustic panels and acoustic ceilings marketed to architects, specifiers, and end-clients in offices, education, and healthcare. Comparable on fabric-wrapped panel product (akin to Soundtrac) and specifier-led sales motion across Europe.
• Offecct (Flokk / Offecct Acoustic Hub): Swedish/Swiss acoustic design brand offering wall panels, ceiling baffles, and pods for offices, education, and public spaces. Closely comparable product mix (panels, baffles, pods) and segment focus, with stronger brand and European distribution than Acoustic GRG.

Broad incumbents

• Saint-Gobain Ecophon: Saint-Gobain subsidiary that manufactures acoustic ceiling and wall systems for offices, education, and healthcare. Competes with Acoustic GRG in non-residential acoustic treatment, especially the Education and Commercial Office segments Acoustic GRG serves, with global distribution and R&D resources Acoustic GRG lacks.
• Knauf (Knauf Ceiling Solutions / AMF): Global building-materials giant (Knauf Group) with a dedicated acoustic ceiling and wall panel business (formerly AMF, Heradesign) supplying commercial, education, and infrastructure projects worldwide. Overlaps with Acoustic GRG's wall and ceiling panel range but at vastly larger scale and broader geographic distribution.
• Armstrong World Industries: Large publicly traded manufacturer of acoustic ceilings and wall solutions, including the Soundscapes and OPTIMA lines, with deep specification relationships with architects and contractors globally. Directly comparable to Acoustic GRG in product function but with vastly broader product portfolio and international presence.
