An acoustic louver creates the ideal acoustic barrier in ventilation apertures in structures, and is suitable for several applications as air inlets and outlets in both processing plants or naturally ventilated areas. In addition, louvers can be used as screening walls around ventilated enclosures in processing-/air conditioning-/or electrical generator plants. Available options with the louvers are bird mesh, water trap and flange connection which should be specified separately. The SRI1 type is best suited for outdoor use in rough weather conditions, typically in an offshore environment.
Material and dimensions:
The dimensions of a louver should not exceed 7m2 due to practical considerations, and if larger sizes are required a multi-sectioned solution should be used instead. Minimum size of a louver is recommended to be 1m2. The material alternatives available for the louvers are: pre-galvanized steel, aluminium and stainless steel. Painted finish of the louver is available upon request. The insulation material used consists of non-toxic and non-combustible mineral wool, and is firmly covered by polyester or glass fibre cloth and a perforated plate.
Noise data for the louver is available according to the following standards:
The sound reduction achieved by a louver is heavily dependent on the sound field and by the surrounding arrangement. This is why measurements on site will often vary from laboratory measurements, because the louver on site will be affected by factors as flanking noise, background noise, vibration etc. In order to get the best possible result, please contact Acoustics for accurate noise calculations for your particular need.
