Noise Reduction ( dB)
The product can be manufactured from Aluminium, Colourbond or Zincalume and finished in a colour to suit requirements. Louvre widths are available from 500mm up to a maximum of 2000mm. Where larger openings are involved use multiples of suitably sized equal units. Where louvres are installed into steelwork, allow 3mm clearance all around the louvre.
Where louvres are installed into masonry, allow 6mm clearance all around the louvre.
The louvre provides a moderate level of weather protection. There is a single water channel at top of each blade. The design, angle and length of blade limit water ingression which is drained via the sill.
The HC305 will provide good noise reduction. Please see above insertion loss test results for performance.
Free area ranges between 33% (2 blades) to 59% (15 blades) depending on height and width of the louvre.
HC305 is available in modular form, but can be engineered to fit custom sized openings to suit requirements.
