BASWA phon Fine Acoustic Plaster System

BASWA Phon Fine represents the pinnacle of elegant, high-performance acoustic surfaces. It delivers an ultra-smooth, fine-grain monolithic finish that looks identical to premium traditional drywall while invisibly managing internal echoes. Expertly installed by Arthur Acoustics—the UK's premier certified specialist in advanced architectural acoustics—this system blends pristine minimalist aesthetics with exceptional noise reduction.

For spaces demanding sharp design purity alongside optimal acoustics, BASWA Phon Fine offers the perfect architectural solution. It completely eliminates the need for unsightly industrial sound panels, allowing ceilings and walls to maintain clean, unbroken, and sophisticated profiles.

What is BASWA Phon Fine?

The BASWA Phon Fine system is engineered using a precise 0.5 mm grain profile, offering a significantly smoother and more refined surface texture than the Base variant. Available as both a fast-tracked single-coat finish and a premium two-coat (Classic Fine) configuration, the system provides incredible acoustic versatility across complex geometric layouts.

The system layout pairs high-density, factory-coated supporting mineral panels with our microporous marble aggregate top compounds. Sound waves effortlessly travel through the fine marble aggregate surface rather than reflecting back into the room. The sound energy is then trapped and safely converted into microscopic thermal energy within the core acoustic backing.

Performance Benefits & Key Features

Iconic Smooth Aesthetic: The 0.5 mm crushed marble aggregate delivers a beautifully smooth, fine-grain finish engineered for sophisticated, high-end environments.
Class A Sound Absorption: Delivers up to

αwalpha sub w

𝜶𝒘 0.95 (Class A) sound absorption depending on system configurations, rapidly stabilizing reverberation in modern spaces featuring extensive hard surfaces.
Expedited Single-Coat Option: Can be applied as a single-coat top finish, reducing on-site trade times and helping fast-track demanding construction schedules.
Complex Geometric Adaptation: Perfect for seamless flat expanses up to 5,000 square feet without a control joint, as well as barrels, domes, groin vaults, and organic curves.
Moisture & Mold Resistant: The mineral marble compounds are completely inert and non-water-soluble, making them naturally resilient against moisture aging and safe for humid indoor spas or pool environments.
Certified Fire Performance: Meets strict commercial safety regulations, classified as non-combustible (A2-s1, d0) according to DIN EN 13501-1.

System Profiles & Specifications

To ensure compliance with local building constraints and acoustic design targets, the BASWA Phon Fine system is built across four standard thickness options:

System Thickness Sound Absorption Class Primary Design Intent

30 mm High Efficiency (Up to Class C) Shallow voids, space-saving urban retrofits, high frequencies

40 mm Premium Control (Class B) Optimised for standard voice, dialogue, and music ranges

50 mm High Performance (Class A) Medium frequencies, multi-family open lounges, galleries

70 mm Maximum Absorption (Class A) High-volume spaces, multi-height grand reception areas

Custom Tints & Lighting Adaptability

While standard brilliant white (NCS S 0500-N) remains a classic choice, the fine marble formulation can be factory-tinted or precisely matched to any custom RAL or NCS color index without altering acoustic transparency. Furthermore, its precise finish helps scatter light softly, reducing harsh glares in spaces with expansive floor-to-ceiling glazing.
