BASWA One Spray Acoustic

BASWA One | One-Day Impact-Resistant Seamless Acoustic Plaster

​

Arthur Acoustics provides specialist specification and certified UK installation of BASWA One (part of the BASWA Basic One system), an innovative rapid-install acoustic plaster system engineered to complete seamless ceilings and walls in as little as one day. Combining pressure-resistant acoustic panels made from 100% recycled glass with a single-coat marble-sand and glass-granulate finish, BASWA One delivers Swiss acoustic refinement, enhanced surface durability, and unmatched installation speed without visible joints or ceiling grids.

 

Why Architects and Contractors Choose BASWA One

​

Fast-track construction programmes and multi-use spaces often lack the window for multi-day plastering and overnight curing stages. BASWA One solves this challenge by pairing factory-sanded, impact-resistant panels with a single-pass acoustic plaster that cures rapidly.

  • Same-Day Installation Turnaround. Engineered for ultra-fast completion, allowing our certified teams to install and finish up to 50 m² in a single day with minimal site disruption.

  • Enhanced Impact Resistance. Built on a rigid, pressure-stable acoustic board crafted from fused 100% recycled glass granulate, making it resilient enough for both walls and ceilings.

  • Slim 30 mm System Profile. Achieves effective reverberation control within a compact 30 mm total build-up, preserving valuable ceiling height and room proportions.

  • Crisp Architectural Whiteness. Supplied in bright architectural white (~NCS S 0300-N) with high light reflectance to enhance daylight distribution, with custom colour tints available on request.

  • Non-Combustible & Sustainable. Carries a Euroclass A2-s1, d0 non-combustible fire rating, achieves a French VOC A+ rating, and incorporates up to 92% recycled materials to support BREEAM and LEED targets.

 

How the BASWA One System Works

​

Our accredited Arthur Acoustics craftsmen bond the 26 mm factory-sanded BASWA Basic recycled glass panels directly to a stable concrete, plaster, or plasterboard substrate using lightweight gypsum adhesive. Once the panel joints and edge trims are filled and precision-sanded flat, our team applies a single uniform layer of BASWA One microporous plaster across the surface.

Sound waves pass effortlessly through the open pores of the recycled glass and marble-sand finish and are absorbed within the cellular glass backing board. Because the system is sealed at the rear against air movement, it prevents dust-tracking and panel telegraphing over the life of the building.
