Designed for use with the AHL-150 acoustic louver, the ST Series is able to be installed onto the rear of all louvers within the Holyoake range for improved attenuation performance. The acoustic insulation has been engineered to maximise sound absorption whilst minimising moisture absorption. Even when exposed to an atmosphere of 50°C at 90% relative humidity for four days it showed a moisture absorption by weight of less than 0.03%.
