Acoustiblok 3 mm (1/8″)

Revolutionary 3 mm (1/8") stiff, flexible sound proofing material for residential, commercial and industrial situations. Acoustiblok attaches to wood or metal studs under plasterboard, floors and ceilings. When installed correctly in a stud wall, lab tests indicate, it reduces more sound than 305 mm (12 inches) of poured concrete! Acoustiblok received an award for its sound abatement qualites from the Noise Abatement Society. It reduces noise, weight and potential for litigation. Acoustiblok increases privacy

Acoustiblok-Wallcover™ Soundproofing Material


Acoustiblok-Wallcover Soundproofing Material

For the majority of people who find they have a need for soundproofing, this discovery usually comes after construction of the walls are already complete. Since the most effective noise deadening material has always been applied to the studs under drywall, the only option for postconstruction noise abatement was to remove the drywall, change out electric sockets, and make other changes that require demolition and construction of new walls in order to properly install soundproofing within the wall.

It should be noted that soundproofing is impossible to achieve outside a total vacuum; therefore, only percentages of noise reduction are possible. This reduction is measured in decibels (dB). 10 dB represents a 50-percent reduction or increase in sound to the human ear. In addition the frequency ranges of the noise or sound is where we should be concerned with; i.e. speech, TV, etc.

Until the release of Acoustiblok-Wallcover, there was no simple do-it-yourself (DIY) noise deadening solution that could be applied on top of an existing wall. Previous methods required adding an additional wall not touching the original with noise barrier material sandwiched in between. Acoustiblok-Wallcover allows anyone to easily add Acoustiblok® sound deadening fabric to the existing wall without the need to add a second layer of drywall construction. While Acoustiblok-Wallcover is more of an initial investment than the standard Acoustiblok material, it is far less expensive and takes up far less floor space then additional walls and drywall methods.

Recent laboratory tests have concluded and demonstrated that the high STC (53) noise barrier acquired by using one layer of Acoustiblok in a stud wall can now also be achieved using the Acoustiblok-Wallcover on the outside of existing drywall. It is still advisable (and less of an investment) to install the Acoustiblok sound barrier material to the stud within the wall if at all possible in new construction before the drywall goes up, or during a renovation when the walls are being removed and replaced.

In a residential environment, the predominant noise issues will be in the vocal, TV, and certain musical frequencies. The human ear is most efficient (or perceptive) in the 4000 Hz range which is also the range for speech. In light of this, while the STC rating (STC 53) is exceptionally good and well above the standard stud wall, it is even more important to compare the graph of frequencies in which the noise occurs.

In laboratory testing, a precisely built-to-code standard stud wall was acoustically tested. The SAME wall, after adding the Acoustiblok-Wallcover revealed that in the 4000 Hz critical range, the Acoustiblok-Wallcover reduced the sound by an amazing 14 dB. To the human ear this represents a reduction in noise of more than 60-percent. At this time we know of no other such material added to an existing wall that will come close to this level of noise abatement. It should be noted however these are exact laboratory results and while they are good, your results, may not be as good. This is due to sound transmitted from one room to the other through adjoining floors, side walls, ceilings or attic spaces. The technical term for this is “flanking”.

In recent controlled field tests of a duplex (two identical dwellings sharing common roof, slab, exterior walls and an attic divided by one common stud wall), before and after results were commented on by the tenant (a professional writer requiring serious quiet time). Elizabeth Barry, Tampa, FL Stated; “When I first moved in I thought I may have made a big mistake because I could hear every little noise from the adjoining unit. Now since the Acoustiblok-Wallcover went up (on one side only) I don't hear anything from next door. I still hear airplanes overhead and some outside noise but I don't hear anything from the adjacent unit.”

The flexible Acoustiblok-Wallcover material is approximately ¼ of an inch (6.35 mm) thick and is available in 4’ x 8’ sheets. The exposed surface is a fire-retardant silver fabric finish that can be finished just like drywall in any number of textured finishes, painted or covered with wallpaper.

Two to three people are required to install the flexible sections, which are approximately one pound per square foot (ideally, two people at the top and one below to align and press the material against the wall). Each section is attached to the wall using a trowel applied wall adhesive. Spray-on contact adhesive may also be used but is less forgiving.

Considering the performance of this new breakthrough noise barrier material, the applications are immense. Acoustical and thermal consultation is available upon request regarding various applications.

The regular Acoustiblok soundproofing material works in a very unique manner. Rather than attempting to stop or absorb sound as other sound deadening materials attempt to do, the heavy, limp, thin 1/8” (3 mm) Acoustiblok material actually transforms sound energy into inaudible friction energy as it vibrates from the sound. Optimum results in this transformation can only occur if the Acoustiblok material is free to vibrate microscopically. As such, merely gluing it to an existing wall does not provide maximum sound reduction. The Acoustiblok-Wallcover overcomes this by it being separated from the wall with an attached soft, compressible but very strong material currently used in the aerospace industry. This unique material is a closely meshed, highly crosslinked molecular structure involving extremely thin (6 micron) rigid cell strands and filaments.

This mechanical isolation material allows the Acoustiblok-Wallcover to work optimally in transforming sound energy into inaudible mechanical friction energy, creating a unique sound barrier on any wall.

NOTE: Due to the unique nature of this material and a critical manufacturing requirement, it is possible that there will be some very small superficial blemishes. Although industrial and commercial usage has not considered this a concern, consumers may consider using a little joint compound. This will in no way reflect the soundproofing characteristics.
