Moreover, unlike MLV, green glue looks just like the wall.Ī layer of green glue between 2 drywalls is a very effective solution to curb excessive noise. It works really well to seal small holes and cracks in the walls. Green glue is an acoustic adhesive that is used for soundproofing very frequently. Green Glue VS Mass Loaded VinylĪdding a layer of the drywall along with green glue will result in better efficiency and noise dampening when it comes to walls. This sound blocking and flexible material is also known as “Limp Mass Barrier“. Mass loaded vinyl is a, surprisingly, thin barrier material that adds mass to walls and ceilings to block any kind of noise. Mass loaded vinyl, or MLV, is a heavy, limp vinyl sheeting material that usually has been impregnated with metal particles to increase its mass.

Sound Solutions that offers free shipping on orders of 99$. Look at the numbers below to get an idea about how effectively lead can work to block noise, as long as you don't mind toting the extra weight around in your truck LOL!!! The advantage of using sheet lead (ignore it potentially toxic properties for now) is that it is MUCH thinner and MORE MALLEABLE for the same sound blocking effect!!! For example, 1#/Sf sheet lead is only 1/64" thick.so I bought some 2#/SF (1/32"thick) lead and encapsulated in PSA CCF to lay on the floor of the truck and it was extremely easy to mold into the floor pan and over the tranny hump then MLV would have been, as well as providing me TWICE AS MUCH MASS to block engine, tire, road and tranny noise coming from underneath the truck.
Get yourself a 100 sf roll of their quality 1#/sf MLV and your mostly set-Ĭlick to expand.1#/sf MLV is approximately 1/8"thick, but by the time you combine it wth another layer of 1/8" CCF, you are dealing 1/4" thick.Īt least in my truck, I had no problem getting the door panels back on with the imbued thickness, though YMMV in other types of (read more modern) vehicles. The best place, IMO, to get the MLV is from Trademark
The proper application of CLD, CCF and MLV is what effectively quiets the listening space in your already loud truck. Needless to say, the MLV or sheet lead is extremely costly to ship so that many openly choose to not use it. weight per square foot) is what is effective at BLOCKING sound waves (like road or engine noise) and by adding 100% coverage (LOL minus the windows) you turn the trucks cabin into a space MUCH more conducive to listening to the finer details of the music you want to hear. doors, back wall, even ceiling though not necessarily floor) are done at 30% coverage, you SHOULD use the money to apply 100% coverage of a thin closed cell foam (like ensolite or Resonix also sells a quality CCF) and the most important part, 100% coverage using a dense material like MLV (mass loaded vinyl) or even thin sheet lead!!! Mass (in this case. That said, once the larger, unreinforced panels (i.e. In short, further application of CLD beyond this point on the same panel will achieve slightly more acoustic damping, but at a MUCH reduced rate of cost effectiveness. One if the best things that Don ever did besides offering high quality, properly designed acoustic products, was to explain that by using a properly designed CLD applied at approximately 30% of the center portion of a panel is just as acoustically effective, and more cost effective, then using 100% coverage of an inferior product.
