There’s several method for installing mass loaded vinyl to acquire maximum effect. The conventional of a is to set up the MLV right to the stud or joist framing utilizing an industrial stapler or heavy-duty roofing nails which have the large plastic heads. This process is called the membrane or septum method. The MLV is useful when added to a wall or ceiling in a membrane fashion, nonetheless it can be sandwiched between 2 layers of drywall repair dc and other kind of wallboard. The jury is still out about what thicknesses of drywall is best. For better frequency diffusion, it is most beneficial to employ a layer of 5/8″ drywall then the MLV as a septum (a sandwich) and you can add a coating of ½” drywall or Homasote. The dissimilar materials do assist in the soundproofing effort especially whenever we are looking to get every STC point we are able to get with as little effort as possible.
There’s not lots of info on the Web in regards to alternate types of mass loaded vinyl installation, hopefully we will have the ability to explore this here.
If you’re constructing walls utilizing the staggered stud method, it would be beneficial to really weave the vinyl in a out from the staggered stud assembly itself. The aforementioned picture provides you with a difficult concept of how this could look. The important thing to weaving MLV (or any barrier material) is to seal the vinyl as best as possible. In case of an outside weave (most common weave) it is most beneficial to overlap the seams by at the very least 1″ and seal that overlap with acoustical caulking along with a quality seam tape. The weaving of MLV also aids in the defusing of sound waves. This works much like the dissimilar materials except “turbo charges it “.
You may also utilize the weave on a typical stud wall provided there is no drywall installed on either side of the studs. (just open studs) This weaving method may be foiled by stud cross members, therefore it is best to possess only vertically installed studs if you should be planning to complete the weave. If you weave the MLV on a normally studded wall, there may be issues with the drywall sitting level on the studs. If your studs are 16″ on center, then every other stud may have 1/8″ of increased width set alongside the studs that don’t have the MLV weaved a top of them. To keep the drywall even on both sides, an audio isolation tape may be honored every other stud that that is not covered with the weaved MLV this may make all the stud surfaces flat and even and the drywall will rest evenly on the studs.
From the feedback of our drywall installation dc in the field, we have found that the more a wood structure is dampened, the higher the soundproofing will undoubtedly be in a wall or ceiling assembly. That is particularly true for impact noise from above. There are many ways to dampen a wood frame assembly and some are more effective than others. Some contractors purchased blown in cellulose in order to dampen the joist or stud structures, but cellulose doesn’t have mass and though it will help to a qualification, it’s not as effective than using blown in closed cell foam, or my favorite (which requires some ceiling demo) is to line the cavity areas between studs and joists with a sealed cell vinyl nitrile foam mat (America Mat is a superb choice) for maximum dampening. The foam mat would be glued to the studs and the wallboard in the stud cavities (provided you have drywall using one side of the wall only). This insures that the wooden structure is completely dampened and if sealed properly will offer extra soundproofing as a result of sealing those cavities. Sealed dead air space is God’s natural soundproofing method, as I prefer to call it. I believe you have read many of the analogies regarding sealed dead air. If you could actually seal the dead air space and actually create a vacuum in that space, you’d be amazed at the total amount of sound transmission that could be blocked.
