BASWA Basic | Cost-Effective Single-Coat Seamless Acoustic Plaster
 

Why Architects and Contractors Choose BASWA Basic

​

When a project requires a clean, monolithic acoustic ceiling without the multi-coat installation time of flagship systems, BASWA Basic provides a practical, high-performance entry point into seamless acoustic architecture.

• Economical Single-Coat Application. Applied in a single finishing layer over pre-coated mineral wool panels, reducing labour hours and overall installed cost.

• True Monolithic Visual Continuity. Eliminates unsightly suspended ceiling grids, joints, and perforated panels across flat ceilings and upper wall zones.

• Certified Class A Sound Absorption. Effectively tames harsh reverberation and improves speech intelligibility in busy spaces, achieving up to 0.95 NRC.

• Consistent Natural Marble Finish. Features a uniform 0.7 mm marble-sand grain in crisp architectural white (~NCS S 0500-N) or custom RAL and NCS colour tints.

• Non-Combustible & Sustainable. Carries a Euroclass A2-s1, d0 non-combustible fire rating, is 100% VOC-free, and supports BREEAM and LEED sustainability targets.

 

How the BASWA Basic System Works

​

Our accredited Arthur Acoustics craftsmen bond high-density, pre-coated mineral wool acoustic panels directly to solid concrete soffits or conventional plasterboard substrates. Once the panel joints are filled and precision-sanded flat, our team applies a single uniform coat of BASWA Basic microporous marble plaster across the ceiling.

Sound waves pass freely through the open pores of the 0.7 mm marble finish and are absorbed within the acoustic backing board. The airtight rear construction prevents air circulation through the panel, protecting the finished ceiling against dust staining and panel telegraphing over time.

• Sound Absorption Performance. Certified Class A sound absorption with Noise Reduction Coefficient (NRC) ratings from 0.80 up to 0.95, depending on system depth and mounting configuration.

• Surface Finish. Single-coat microporous marble-sand aggregate with a 0.7 mm grain diameter.

• Fire Classification. Euroclass A2-s1, d0 (non-combustible) to EN 13501-1.

• Humidity Resistance. Suitable for damp environments and indoor pool suites up to 90% relative humidity.
