Noise and Heat Insulation

[VladTepes]

Firstly let me assure you I have searched and read various threads on sound proofing and insulation, however many of these are now quite old.

Naturally I am looking for an inexpensive (or at least not very expensive) solution.

Of particular interest:

1. I need to re-do my roof lining. Will be sticking something direct to the roof panels. Was thinking of using marine carpet or similar - suggestions for a good material ?

2. Trans tunnel, floors, seat box - to reduce heat (esp noticebale at the trans tunnel) and noise.

3. Under - bonnet. The standard rubbish is coming off and I ant to replace it with... ? Also has anyone put seals around the bonnet to stop the escape of noise from the rear and sides of the bonnet ? if so - what / how ? (and did this have any negative effect on cooling) ?

Any other suggestions also welcome.

I'm especially interested in opinions f those with direct experience - both things you;ve done that you like, and things you may have done and regret (always best to learn from others mistakes)

Thank you all.

me an dad fully did my fender day after we got it from the dealer, tranz tunel, seats floors everything,,, roof, boot,

but probly the best thing we ever did was put a big thick cote of tar stuff in the wheel arches, made the bigest diff from when rocks fly off the weels on dert roads, now we cant here eny at all,,

the sound/ heat stuff we used was like a insulator we got from clark rubber, i cant remember the prices(as it was 4 yrs ago), but it was well worth it, my car you can be doing 110 and have the radio on and still talk normaly, its unbeleavabul how much of a diff it made, but deffs do the roof,,, stoped a lot of heat in mine,,, as my car it gun gray,

was alot of work and brocken clips tho,:D:D but well worth it,

I've used Dynamat on any panel that can drum. Very good but does cost a bit...saying that, I think it was worth ever cent considering the difference it made. I bought mine on ebay but you can get it at places that sell the car audio goodies. I wish I had used it to line the roof before I glued the carpet on! Carpet alone doesn't cut it, you need to deaden the panels first. 3m also does a similar product (not quite at good but cheaper), I'll look in the shed to see what it is called.

Yes brand names and retailers details of any products mentioned in this thread are all very helpful, thanks.

I can vouch for that stuff in a boat, I have a 4cyl turbo perkins in a 12mm ply box and after I put that stuff in it was at least 75% quieter, it has a thin layer of tar, then foam, then a silver reflective coating.It's also self adhesive.
Amazing stuff on our boat.

Have a look at LRHybrid100's (now ex) 110:

Specifically Mod 18 and Mod 19

http://www.users.on.net/~LRHybrid100/D110.html

I'm sure that he could give some feed back on how the stuff worked from his trip through Oz.

[austastar]

LRHybrid100's page is a great source of information and inspiration.
Looks like scary amounts of $$ can be spent, but it was great being able to see the photos of it being done.
Looks like the site is a Work in Progress, the pages from the seat mod and beyond don't seem to link.
cheers

Yeah i was just having a look at teh site its fantastic but yeah not all there ?

So Im looking at this issue again and am wondering how I would go about achieving the noise insulation for the roof and marine style carpeting. Can one just go over the other ? Could an automoticve trimmer place do this for me ?

If you already have ther roof panels, then LRHybrid100's method is the way to do. Take your insulation material of choice, cut it into panels that fit snugly between the roof framing, and use contact adhesive to stick it in place.

When that's all done, and you are happy with the state of the roof panels, refit them over the insulation. Otherwise, recover them with marine carpet, and then refit them over the insulation.

It should be a pretty straightforward operation (I'll be doing it in the next week or so), and personally I wouldn't bother with the additional expense of an automotive trimmer. That part is up to you :)

I won't be refittig the original hoodlining (if thats what you mean by roof panels) as removing it provides useful extra headroom.
Can you lay maribe carpet over insulation that's been contact-cemented in ? Would it hold long term ?

just after I got my 130, I grabbed a 4L can of body deadener from super cheap for about $40 and a $3 paintbrush.

I have painted the entire bottom of the truck, wheel arches and the inside of the roof with it. Its messy and is about as thick as tar, but the difference was amazing.

I hope to paint the inside of all 4 doors someday too.

Hello Vlad,
I know we have discussed this at an earlier time, and I have a thread in a previous post.

Just a word of caution, be weary of open celled foam, and lead mix materials. They absorb a lot of water, and you know how waterproof a Defender is. :o

I am looking at removing the roof lining and painting some anti drumming material there, and adding some 10mm closed celled foam with aluminium backing on it. I have purchased some in the past from Clarke Rubber for around $70 dollars a sheet. Part of the treatment will to be cut more noise, and part to cut the heat transmitted from the roof. Besides the firewall this is the last place to do.

The best heat treatment has been lead, aluminum shielding around the transmission tunnel, and into the footwells.

Once this house is sold, we are off to the beaches north of Cairns for a change of lifestyle. The air con struggles here in Melbourne, and to be honest, it is rarely used. Just put the windows down, and turn up the stereo. Up there might not be the best option if it is too humid (i.e.******* down rain).

Want to do this before the drive up, to make it a more comfortable and fun journey. Now just have to finish this house!!!!

Cheers,

Ken

I'm in the middle of doing the same thing myself. Maybe this will help...

Hey Fraz,

Thanks for this tip.

The noise that rocks make when flicked up, hitting underneath the rear guards is deafening.

Wasn't sure what I was going to do, until now. :D

It would not be unreasonable to think that LR should have had this sorted by now.

Thanks anyway

I used a combination of Herculiner, 10mm foam rubber with the foil backing and body deadner/rust preventer sparycan stuff under the car.

The only place Ill be redoing is the rear wheel arch's the body deadner hasent worked that well when rocks flick up.

Very happy with the outcome and is alot quieter.I used herculiner and foam rubber on the firewall.
