Hi all,
I'm doing the van conversion. My T6 SWB has no windows. I'm looking for the best solution of the noise reduction when I'm parked near the highway or/and nearby there are trucks with working engines. That happens veeery often when I travel around Germany. I don't care about the sound while I'm driving, at all. Only when I sleep
So, I need to insulate mostly my walls. And I'm thinking to do the ventilation in the roof (out) and floor (in) - that should also reduce the noise, probably that will add the most impact because I don't need to open the tailgate or windows while sleeping. Also I have an auxiliary heater.
I'm thinking to glue the XPE (X-linked Polyethylene Expansion) mats on the metal case (for thermal insulation mainly) and on those mats to hang somehow MLV (mass loaded vinyl). Ofcourse the butyl anti-vibration layer will be the first.
Or maybe it is ok to put something like synthetic felt instead of MLV (or additional to it)?
But the case of the car has ribs. And I'm NOT going to put XPE + MLV on the ribs, because it will eat the space. So, the material will be located between the ribs. On the ribs I will put 3 mm XPE and the attache the decoration panels (wood)
I know the noise will still go through the ribs. But.. does it mean the sound insulation effect is totally low or it still worth to do it?
Maybe any other ideas? Maybe the active noise reduction where the speaker is the van's metal case itself haha?
