Acoustic louvres are designed to allow ventilation while reducing the transmission of unwanted noise. The performance depends heavily on the materials and construction of the blades.

Ventuer acoustic louvres are manufactured from aluminium components, rather than folded sheet metal which is commonly used in the market. Folded sheet metal, whether galvanised or painted, relies on protective coatings for corrosion resistance and can be susceptible to degrading overtime. Aluminium provides corrosion resistance, improving durability, particularly in exposed environments.

The extruded aluminium nosing is a key part of the acoustic blade profile, allowing for precise and repeatable geometry, including twin weatherstop profiles without requiring additional components.

Extruded aluminium also helps maintain straight and consistent blade profiles over longer lengths. For architectural applications this is important where appearance are equally important to acoustic and ventilation performance.

The extruded nosing combined with perforated aluminium forms the blade profile, which is then filled with mineral rockwool insulation.

The perforated aluminium allows sound energy to enter the blade, where it is absorbed by the rockwool core. Rockwool is non combustible, moisture repellent and vapour permeable, helping prevent moisture accumulation within the blade while maintaining stable acoustic performance over time.

Together, the aluminium construction, perforated surfaces and rockwool insulation creates a durable acoustic louvre system designed to manage airflow, weather exposure and noise.
