Acoustical Properties of Stretch Ceiling

Reverberation of sound in a room, at a venue, or in an office can wear people out, complicate communication, and diminish the quality of music. Improving the acoustic performance of a premise is an important application for stretch technology products. Both PVC and canvas stretch installations can be used for this purpose. The installation of a standard stretch ceiling membrane improves a room's acoustics, while the use of special micro-perforated membrane materials will further amplify the sound enhancement capabilities of stretch ceiling structures. Micro-perforated membrane has openings of only 0.1 - 0.2mm in diameter and has no adverse impact on the product's visual properties.


The ASTM C 423-1 Sound Adsorption Average (SAA) measurement for acoustic micro perforated film is ~0.45. The Noise Reduction Coefficient (NRC) according to the same standard is 0.45. The weighted sound adsorption coefficient (WSC) according to EN ISO 11654 is also 0.45. Our micro perforated film is qualified as Class D under the same standard. If this film is combined with insulation behind the stretch ceiling in the structure, the acoustic parameters can be further improved, reaching SAA ~0.77-0.78; NRC ~0.8-0.9; WSC ~0.75–0.85, and Class C or B. Combining the membrane with plaster board and Isover™ glass wool achieves a Class A qualification and sound insulation better than 35dB.

The combination of superb acoustic properties with an unparalleled visual impression make stretch ceiling technology one of the most popular instruments for improving the sound properties of a wide range of buildings, from regular households to theatres and exhibition halls.
