I have seen many different types of CCF with differing density ranges. Is there a best type for use under MLV and thickness?
Duly noted. I'd skip the ccf (step two) and go straight to mlv then. Then again having ccf close to the thickness of a quarter does very little. What's the point?Ccf doesn't reduce noise by any noticeable amount. You need a mass loaded barrier foe that, which raamat doesn't sell. If you use overkill from second skin to reduce noise, the results wouldn't be any better.
I understand this. I have one layer of cld down paired with the ccf and the cost to benefit ratio for reducing the noise in the cargo area was negligible.I believe that the point of CCF is to isolate vibration and transmission between two adjacent surfaces…used only by itself, it does nothing to quiet anything…CCF does NOT dampen panels and it does NOT stop sound transmission. That being said, when used in conjunction with CLD and then MLV, it increases the effectiveness of both by preventing remainaing panel vibrations from being transmitted to and through the MLV. You do NOT want to skip the CCF!!
It can also be used to prevent rattled between adjoining objects, which does help quiet the interior.
I'm curious on what the slightly better qualities of neoprene are?1/8" neoprene is inexpensive and has slightly better qualities than regular ccf.
Neither CLD or CCF is used for reducing road noise…that is the job for MLV (or sheet lead..lol).I understand this. I have one layer of cld down paired with the ccf and the cost to benefit ratio for reducing the noise in the cargo area was negligible.
I commute 4k a month 2 hrs each way and know every rattle and noise. The road noise is still present. Did it reduce it a little? Not imo.
Probably "crush" properties. You do not want you ccf to crush.I'm curious on what the slightly better qualities of neoprene are?
Bah! Snake oil I say! Buy THIS and THIS then it'll make your car quiet. You're good but...no. LolNeither CLD or CCF is used for reducing road noise…that is the job for MLV (or sheet lead..lol).
If you take the time to add a layer of MLV to the CLD and CCF that you have already installed, you WILL notice a marked reduction in road noise!! It is important to note that these materials ALWAYS work best when used in conjunction with each other rather then alone.
I would agree with this statement…it is also why I prefer the CCF from sds as it is substantially more "crush resistant" then Raams. Not sure if neoprene or Dons ccf is less expensive.Probably "crush" properties. You do not want you ccf to crush.
I believe 1/4" is recommended for use in the floor footwells (think of where your floormats go) to add a little more cushion. 1/8" everywhere else.Correct me if Iam wrong, but going with a 1/4" CCF vs 1/8" offers zero advantages....its simply a decoupler...if anything, get thicker MLV if you have the room.
