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%.
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 is a rockwool product with thermal and fire resistant properties. The insulation has been engineered to meet the requirements of NCC 2022 Volume 1 C2D10(1) when tested or assessed in accordance with AS 1530.1 and Volume 1, S7C7 for insulation materials. When assessed to AS/NZS 1530.3 the insulation does not exceed the ‘Spread of Flame’ or ‘Smoke Developed’ indices of Table S7C7
