Sound Testing & Acoustical Analysis Service.
T
his service offers you the customer a detailed report on; Reverberation time,decibel levels, 1/3 octave band analysis, transmission loss and ambient noise levels. Taking these acoustical measurements at your facility can be very expensive, but the advantages and the end results outweigh the initial costs.Call for details. Reverberation Calculation. If you have an area with a long reverberation(echo)time, call us and we will help you figure out the exact time in that area and then we will advise you what you will need to do to reduce the reverberation time by installing the most economical and correct acoustical material(s).

STOP NOISE by using or noise control Barrier for walls or ceilings. USE our Acoustic Decoupler under carpeting, vinyl and ceramic tile to STOP foot-fall (Impact) noise as well as airborne noise from going up and down through the floor! There are many different barrier/foam composites available for any type of application. Call with questions so you are sure to get the right product reccomendation for YOUR exact needs.

Interesting FACT:
A 20-decibel reduction (20 STC) will reduce the noise heard by 75%. Therefore, our acoustical barrier stops 75% of the noise heard through a standard wall.

BARRIER is 1/8" thick black vinyl (1 lb/sq ft) with an STC rating of 27and has about the same noise stopping ability as a 5" drywall/stud wall. Achieve a total STC of 45 in an existing wall and stop about 2/3 of the noise heard thru that wall. STC and IIC Ratings for Various Configurations. Hardwood floor STC/IIC Assembly Barrier is installed by stapling, nailing (roofing nails work best) or screwing. In a new wall, ceiling or floor, attach the barrier directly to the wall studs, the floor joists or ceiling rafters and then cover with dry wall, wood paneling or flooring material. Achieve a total STC of 53 for new wall construction which stops 75% of the noise heard thru a standard wall. STC and IIC Ratings for Various Configurations. Hardwood floor STC/IIC Assembly On a finished wall or ceiling, the barrier works best by attaching it to furring strips at least 1/2" thick to decouple it from the wall and then covering the barrier with sheet rock or wood paneling such as our red oak Tambour T831FRP using our Loctite glue.
Do not be misled by "fancy" and expensive products such as Homosote, Soundboard, QuietRock or the use of resilient channels. (Read why the use of resilent channels is not suffient enough for proper noise reduction)
Numerous clients call us who have used these so called "noise control products" and reported to us that they were not happy with the end result. None of our customers are calling us with the same complaint. Our barrier is very easy to work with and WILL SOLVE THE NOISE PROBLEM! Don't be confused by more technically sounding solutions. Our vinyl barrier will do the job cost effectively. The other products cost per decibel(STC) reduction is more then 2 1/2 times as much as the cost of our vinyl barrier. Barrier can also be laid above acoustical tiles to prevent noise transfer thru the plenum. Numerous customers have called us after using the other products and have had to redo their walls, ceilings and floors because the other products do not perform as well as our barrier.

Standard barrier is sold in rolls 54" wide by 30' or 60' long. CALL for details!

Class A Fire Rated Barrier available: Fire rated barrier may be required in commercial buildings and occupied spaces so check with your local fire marshall. Our Class A Fire rated barrier (#FRBAR) passes UL94HB and UL94VO tests and tested by independent labratories. Fire rating for std barrier (#bar) is both UL94 HF-1 and MVSS 302 rating (Class C).

Nylon reinforced barrier can be hung as a curtain to isolate noisy machinery or work stations. Barrier is installed by stapling, nailing or screwing.

Installation Instructions for Noise Control Barrier: For new wall, ceiling or floor construction, attach the barrier directly to one side of the the new stud wall, on the bottom of floor joists or ceiling rafters by using roofing nails or staples to secure the barrier and then cover the barrier with dry wall or wood paneling such as our red oak Tambour T831FRP using our Loctite glue. On a finished wall or ceiling, the barrier needs to be installed on to furring strips(at least a 1/2" thick) that would be attached to the existing drywall spaced 16" on center. This allows the barrier to be decoupled from the wall which allows the barrier to absorb the energy and eliminate it. You then cover the barrier in the same manner as mentioned above. Barrier can also be laid above acoustical tiles to prevent noise transfer in to the plenum. Numerous customers have called us after using the other products and have had to redo their walls, ceilings and floors because the other products do not preform as well as our barrier. Fire rating for std barrier (#bar) is both UL94 HF-1 along and MVSS 302 rating (Class C) which were tested by an independent labratory. Our nylon reinforced barrier can be hung as a curtain to isolate noisy machinery or work stations.

BARRIER backed with 1/4" NEOPRENE stops noise thru CARPET. Simply roll out over your floor and then put the carpet pad and carpet over it. The high quality neoprene will not break down over time and decouples the barrier from the floor making it effective. Achieve up to a total STC of 70 and IIC of 91. STC and IIC Ratings for Various Configurations. 1/8" barrier plus 1/4" neoprene is sold in 54" wide rolls x 20' lengths. (BARN-20)

BARRIER backed with 1/4" URETHANE foam stops noise thru DOORS, pipes, ductwork, mechanical rooms. This product uses a less expensive open celled urethane foam (vs neoprene) that decouples the mass loaded 1 pound/sqft. barrier from the substrate allowing for an STC up to 27 decibels of noise reduction along with an increase in impact noise reduction. Glue to doors with our Loctite quick grab glue to the side of the door opening in and overlap over the seams. This product can also be wrapped around duct work, pipes, waste lines and installed in mechanical/engine rooms to stop noise from those sources. Each roll is 54" wide x 20' rolls. (BARU-20)
