Very High Acoustic Performance Drywall - PREGYMETAL SINEMAX® - SINIAT

Very High Acoustic Performance Drywall - PREGYMETAL SINEMAX® - SINIAT

ACOUSTIC SPECIFICATIONS COMPLIANCE

> SINEMAX walls meet the most demanding acoustic specifications fully compliant with the sound requirements of the CST Guide issued by the French Image and Sound Technical High Commission.

> For acoustic measurements in situ using the Dolby Atmos sound in a cinema, the noise level in the surrounding room is below the NR 25 graph (CST Guide recommendation).

> The apparent sound reduction index of the SINEMAX partition at the 63Hz octave is 44 dB and 59 dB at the 125Hz octave. HIGH

PERFORMANCE AT LOW FREQUENCIES

> The new SINEMAX acoustic joint contains a higher performance elastomer to reduce low frequency transmissions thanks to its 11 Hz cut-off frequency. It reduces structure-borne transmissions to negligible levels compared to airborne transmissions.

> The replacement of standard plasterboard by high-density PREGYPLAC dB BA13 acoustic plasterboards provides a high level of sound insulation straight from lower frequencies.

THE SINEMAX SOLUTIONS FOR STRINGENT TECHNICAL REQUIREMENTS
> Rw + C from 69 to 76 dB thanks to new SINEMAX joints and PREGYPLAC dB BA13 and PREGYPLAC BA18 S boards.
> Height: up to 14.10 m with standard PREGYMETAL columns.
> Thickness from 260 to 640 mm to suit all configurations.
> EI 60 fire resistance and R 60 fire stability for enclosed structures.
> Impact resistance with High Strength Hardnedss PREGYPLAC BA18 S boards
SITE PRODUCTIVITY AND BUDGET CONTROL
> SINEMAX installation uses the same techniques of dry plasterboard wall construction. It adapts perfectly to metal constructions and light façades and will help in meeting very tight construction deadlines.
> The job of the plasterboard installer is made easier by products that are suitable for high-wall constructions. PREGYPLAC BA18 S plasterboards have a reduced width of 90 cm and PREGYMETAL standard frames are made of 6/10° steel. These products simplify handling and screwing, while still ensuring health and safety compliance - installer safety.
> Budgets are optimized by a 30% decrease in the framework density, with the new 90 cm spacing between columns of the BA18 S boards.
> Site supply ensured. With a reduced quantity of accessories, boards and frames are readily available to ensure deliveries and construction stocks.
