Anyone else have a 7.3l diesel motor in their skoolie?? well i do, and it is LOUD. the firewall is paper-thin and it just doesnt cut the engine noise like a skoolie should. i want to put speakers and a stereo in it, but until i cut down the road noise their is no point.
other than expensive dynamat, what can i do to soundproof the inside of the bus? i was thinking using old egg cartons. just kidding. but could i use some cheap foam spray? carpeting? any ever done this before?
I have been wondering the same thing. About half of the factory insulation on the inside of my engine cover(TC2000) is missing and I think I want to redo it better than the factory did. Would really like to see how they did the engine cover insulation on the FE Wanderlodges. I have a section of dynamat that is stapled to the inside of a closet door in the garage, I need to peel it off and look at it closer. I'm wondering if there is comparable flame retardant material available by the the yard at MacMaster Carr.
On mine I pushed carpet and padding up on the firewall. It seems to help but when I decide to open the right side window or jackknife door it does make it harder to hear the radio unless it is at full level. My speakers are in the front panel above my head.
I'd say the more you stuff at the firewall the better results you will get. I did get my padding for free and the throw away carpet on top. I think it was removed from a house cause someone didn't like the color. This stuff use to look new.
Don't the Wanderlodges also carpet most of the inside too to help deaden the sound. Carpet really does help kill the sound and gives a little insulating too.
i recently came across a large amount of free carpet padding. i will soon take apart the front of the bus and secure the padding everywhere i can. in places i will use dynamat but not everywhere because dynamat is not cheap. i think the carpet padding will work fine if i glue it down, and use it EVERYWHERE. i even bought a $5 can of spray foam to see how well that works. pics to come.....
I was looking at a similar product for use as a headliner for my bus. I wonder how expensive the Bondedlogic stuff is for a roll. I was quoted $155 for a 4x125 ft roll of similar stuff. I do like the backing on this better...I might have to contact the company as well. Thanks for the link!
I used carpet to cover the firewall and floor under the drivers seat, I also covered my stair well with a cover and that makes a big difference in for noise, wife and i can talk to each other almost in a normal voice.
