The Holyoake AHL-150 louver offers an attractive louver system that provides ventilation and sound attenuation. Based on proven Holyoake louver technology, the louver has been designed to efficiently allow air to pass through the facade of a building while reducing radiated noise. 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%.

Based on proven Holyoake louver technology, the louver has been designed to efficiently allow air to pass through the facade of a building while reducing radiated noise. 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
