The Model Type R Acoustic Louvre range offers optimum acoustic performance with a minimum pressure drop.
A louvre for when noise breakout is a problem.
The Model Type R Acoustic Louvre range offers optimum acoustic performance with a minimum pressure drop, the outer casing is manufactured from 1.2mm galvanised mild steel whilst the louvres are manufactured from 0.7mm thick galvanised mild steel plate, the inner face being perforated. The infill within the louvres shall be organic mineral wool with a density of 47Kg/m3 and packed with a minimum compression of 5% to eliminate voids. All infill material to be inert, vermin, rot and moisture proof.
Acoustic Louvre screens are manufactured in 1220mm maximum width modules to a maximum height of 3600mm the overall width of the system is 300mm and weighs approximately 50Kg/m2.
Louvres can be supplied with bird / insect mesh and a polyester powder coating finish. When used for acoustic screening the louvres are often supplied as galvanised mill finish with a standard single bank screening louvre attached to the front.
For extreme noise reduction cases the units can be fitted back to back to form a double bank unit known as Model Type 2R.
The most common use of the louvre is for noise reduction, use the following Noise Reduction (NR) Table to specify the appropriate Model Type.
The free field noise reduction of a louvre is the difference, in decibels, between the sound pressure level on the noise source side of the louvre and that measured on the other side of the louvre away from the noise source.
