extra insulation for the cabin?

2nd Hand Yank · Post by **2nd Hand Yank** » Tue Oct 11, 2011 11:32 pm

I was wondering if it'd be easy and worth it to add some extra insulation to dampen sound as well as keep a little of the sun heat out + slower cooldown at night say if I'm camping in my car. I also found heavy rain on my roof to be excessively loud, more so than other cars I've driven.

I have several ideas:

- roll-on urethane bed liner
- spray on insulation, though that could be too messy for inside
- a roll of 1cm thick carpet underpadding that is spongy with a good backing, left over from work.

All of this would be put in after removing my interior trim, then re-installing the interior trim.

Thoughts?

Keep it light, it won't make any difference as most of the heat comes through the glass and it'll stop the heat getting out too, I bought a little 12v computer fan that I'm going to hook up to a small bike battery that I have to keep the air in the esky moving during the day and in the tent at night, cost about $2 delivered from memory off eBay and actually blows a nice little breeze.

I've done this: Removed the Seats and the Carpet, then Covered with "TOFF" Sprayed Bedliner, it not only isolate Temperatures but also Noise.

Off topic but this is one of my pet hates - call me a pedantic bastard - but it is damp, not dampen.

Dampen means to make wet.

Damp means to remove oscillations, in this case sound. (and yes I know damp also means it already is wet

)

That is why shock absorbers are dampers and not dampeners. But don't worry you are not alone - I have seen an advert for a suspension company actually call them dampeners

and on topic - if you want to reduce the amplifier effect of the metal panels in your car (reduce road noise and speaker vibrations) then use dynamat type materials. I have a link at home on how (as in where, not physically how to do it) to apply it - basically you do not apply to the entire panel/floor like you see everybody doing it. If I remember I will post it up.

SORRY Matt SORRY Ken

now thats pedantic

and go with a sound deadener that is rolled on as the spray on paint on stuff is a nightmare to clean off your skin.

I dampened my pants reading that.

+1 for dynamat in the doors. I plan to go the cheap route & get some carpet underlay under my floor & maybe even see if there's enough room above the headliner for a thin layer.

It appears that some dictionaries (dictionary.com) and wikipedia (Sound Damping) would disagree. So interms of acoustic the jury is out but I would lean toward the fact that yes you can use dampen when referring to sound, but definitely not when referring to suspension.

Back on-topic......

Crikey what a thread! hahaha

How would you say my enthusiasm for sound deadening has been dampened?
Or is that damped???

hahaha

thanks niterider.

Is it easy to get these products in WA or sent here?

I work in a shop with a plain tin roof and compared to that,
my L Series isn't much quieter when the rain comes down hard.

Maybe this carpet underpadding isn't a great idea for roof sound damping, as it's a tad on the heavy side

Hmmm, could work...

but both of those "solutions" may bring other problems,
leading to different sorts of long-term bodily-damage or disability.

hehehehe.

I wonder if my carpet underlay is worth keeping for anything other than something to lie on while working under my car.

A giant bubble

haha but seriously now, just saying it cost $0 to sound and insulate under my carpet cause, I went around bulk refuge and found a nice bit of under house carpet foam stuff. works pretty good too.
