Noise attenuation Reduction Insulation Materials, room Soundproofing acoustic
sound Insulation, our room noise attenuation material "MLV" is a
low cost material used for walls, rooms, ceiling in conjunction with mass vinyl
barrier insulation for audio room, echo proofing a room with Egg Crate,
basement, garage, home recording studio and many other noise attenuation
applications. Do it yourself soundproofing, follow the techniques listed below
with Mass Barrier & Rockwool There are several methods to soundproof a room; Pre Construction as illustrated in the graphic to the below or to your right, place rockwool between the 2 X 4's then place mass barrier over the studs, finally placing a layer of sheet rock as the final layer. STC values listed in illustrations below. One deviation of this method is; using resilient channel that can be purchased at Home Depot or Auralex as illustrated to the right.
Post Construction you would need to place furring strips double
thick 16" on center, then place 1" Rockwool in-between the furring
strips and place mass barrier over the studs, finally placing a
layer of sheet rock as the final layer. Rockwool is made of slag, which is a recycled steel product, and rock, a trap rock mined in Texas...those are the only raw materials in rockwool insulation. we use "coke" which is a recycled material from coal. it is used to make the heat hotter in the manufacturing process, in order to save energy...rock wool is the safest insulation on the market today...it also has one of the best thermal insulating properties as well as a superior sound control while not supporting mold or mildew, all while not having to add any chemicals...many other insulation products on the market today are either all chemical, foams, or have chemicals added to them to keep them fire retardant, cellulose... Wholesale mass loaded barrier and other soundproofing materials.E.2.3 Coefficient of absorption. All materials absorb some sound, and the percentage of sound is measured (in laboratory tests) as a coefficient of absorption. Coefficients of absorption range in value from close to 0 (no absorption) to nearly 1.0 (100 % efficient); these coefficients vary as a function of frequency. Materials that are most efficient at absorbing sound include soft porous "fuzzy» materials such as glass fiber, rockwool fiber, carpet, curtains, acoustic tile, and other specialty materials. Materials that depend on their porosity to absorb sound should not be painted which will clog their pores, and thus degrade their acoustical performance. Where to purchase Mass loaded vinyl MLV is a specialty developed mass layer product offering superior soundproofing. Mass Damper sheet offers STC Ratings up to 53 as displayed below. It is a low cost material 
used for a variety of marine and land based building room
soundproofing. The drawings below shows Mass barrier installed as a
suspended mass barrier. This typical application would improve
transmission loss between adjoining room spaces "Residential,
industrial". The combination of the mass damping and stiffness
properties of Mass barrier gives it excellent performance as a
combined layer and mass damper when applied to partition panels and
lightweight structural bulkheads, reducing room transmission of both
airborne and structure Borne noise attenuation. Application direct
to panels is best done with pre-applied pressure sensitive adhesive
(PSA) backed up by minimal fasteners or staples. Ideal product for
sound studio music room, Residential soundproofing, garage, basement
and recording studio and much more.UL 94 HF-1 MVSS 302 1SO 4589-3 Tolerances are 0 +/- 1/8" for width. Acoustic Carpet Underlayment soundproofing is an important part of a boat's sound reduction package as well as a home or office. This easy to install product can be used at any point in the insulation process. Carpet underlayment is effective as a primary treatment for living areas of the boat, such as boat/yacht salons or staterooms where flooring is the dominant source of noise in situations where it is difficult to install proper boat engine room soundproofing. Underlayment products consist of a foam layer supporting an acoustic mass barrier. The foam layer acts to decouple the mass, layer from the floor vibrations, creating an effective mass barrier against noise radiating from the floor due to structure borne or airborne sources of noise excitation. Under-layment is also very effective as part of a full insulation package. In cases where greater attenuation levels are required, this insulation will improve upon the room insulation system. Not only will the insulation add a second decoupled mass, but it will also seal areas such as hatches where leakage can take place. This product can also be used in a household application, such as sound reduction emanating from a basement or a level above. Product is 4-1/2' wide We offer underlayment for areas that have the potential of getting wet. (Closed Cell Foam) Ideal for pool pump enclosures. UL 94 HF-1 MVSS 302 1SO 4589-3 Rockwool stone wool has an open fibrous structure making it ideal for
absorbing and regulating noise. Rockwool products reduce ear-deafening noise
from machines or the activities of people, and provide ambient situations that
allow normal conversation. Mass loaded barrier wholesale prices: 1/8" $1.10 per sq ft. 1/4" 2.30 per sq ft. Not sure of which noise attenuation insulation materials your looking for, call us. 888-270-8555 For large orders, call us for a freight quote.
