Numerous accessories allow us to adapt the soundproof doors to your exact requirements. No matter whether it is a theater, a test laboratory or an industrial plant: Effertz soundproof gates have proven themselves in a wide variety of applications at home and abroad. Tell us what noise you want to shield from what – we’ll tell you which soundproof doors can achieve that for you. We can also meet the demand for particularly high sound insulation values while taking up little space. We offer tested sound insulation for up to 50 dB with robust roller shutter door technology even with little space available. But when it gets loud, your ears will quickly recognize the Effertz difference. Same net free area calculations apply.At just a glance, you can rarely see the difference between Effertz soundproof doors and normal rolling doors. Chevron louvers do not allow a straight path for light/sound, and can dampen sound further than conventional louvers. Once the source of sound has been attenuated as much as possible, and the enclosure has been damped, then you may wish to go to chevron louvers to dampen the sound that is still present. They are used for insulating engine rooms on boats, recording studios, and many other uses. Products like panels manufactured by Soundown are very effective for insulating noise. How about putting anechoic baffles on the walls like the egg cartons we used to put on the garage walls to muffle the sound of the band practicing? How much noise does the pool equipment room generate? It's a pump in there - not a compressor. I seriously doubt that just the louvered door will block the sound to your customer’s expectations if they want something approaching peace and quiet. I was surprised that the noise level did not reach my expectations, but it did become acceptable for the employees to work in the area. I forget what we used, but we did get the noise down a little more. We even covered the block wall with a sound absorbing textured material. We then added filter element material to the louvered areas, to help absorb the noise and not block the air flow needed for the compressors - maybe another 15% reduction. With only the louvered panels in place we found only a slight decrease in the noise level - maybe 15%. The existing shop wall was concrete block and the floor was cement. After considering the matter and finding information that showed that sound waves are directional, we decided to put up the enclosure which was basically a closet built against the existing shop wall, with louvered shutter panels creating the other three walls. We used louvered shutters to create an enclosure for two stationary air compressors that were running close to an area where employees were stationed. Keep in mind that any sort of field modification of a fire-rated door will void the label. There are size limitations with the fire-rated louvers you should be aware of. However, if your door needs to be fire-rated for a mechanical room, you will need to provide a fusible link louver, which has a 40% free air flow. A quick glance at the steel louver catalogs - Anemostat, AirLouver, and etc reveals a 50% free air flow for most louvers. A louvered door will not have any effect on sound deadening, nor is it designed to do so. Sound is a function of moving air, and the air is moving through the louver spaces.Īir flow is one thing, sound control is quite another. I do not think they will decrease any sound. I do not know how louvers can be used to moderate sound levels. Once upon a time, stock attic louvers were labeled with net free area to ease selection. This is used for calculating airflow for equipment or attic ventilation. ![]() Determine the space between the parallel slats - say 3/8", then the length of the that space - say 24", then the number of spaces - say 60. Net free area on louvers is a valid characteristic of louvers and therefore a valid, though obscure, request. The client has a spec that's required but being that it is by the tennis court they don't want to hear anything. A client wants me to figure out the air flow on a louvered door for a pool equipment room.
