soundproofing and insulating a rover

[Dave_F]

OK I know we have all been looking for the "Holy Grail" here but I think I may have stumbled upon something interesting.

How 'bout CORK?

I cam across some at Home Depot recently and it has all the benefits of a closed cell foam however it is much denser.

It would look pretty unique as well.

Thoughts???

[red90]

Closed cell foam is not really a sound proofer. It is really used because it is a great insulator. I don't think cork comes close as far as insulation. No idea about sound blocker capabilities.

Red90, I'm not sure why you state otherwise but in fact, cork is a pretty good sound attenuator and thermal insulator. Those characteristics and being more environmently friendly are why it's become more popular for floor insulation. Dave, it might be worth a try if it's robust enough to take a bit of abuse or if it's covered by something else. There are manufactured cork products (regranulated) that might work well. How does the cost compare to other options?

On sale right now for less than $30 for 50 Square Feet at Home Depot.

It does state that it does increase the "R" value...although by how much or what its own factor is, it doesnt state this.

States that it also is best for absorbing noise, sound impact and vibrations.

100% natural cork granules combined with virgin :lol: non allergenic thermo-closed cell polyethylene.

Lowest VOC's

Naturally resists mould, mildew oxidization and shrinkage :lol: ...that's gotta be good

...and it's recyclable.

It is designed specifically for Above and Below grade wood and concrete.

My only real concern is that it is not very thick 3.2mm but I guess I could double up if necessary at this price.

I'll let you know how it goes and how muck if any difference it makes...plus I would get a built in dartboard :shock:

Cheers,

Also....with all that cork on board you wont need to use the raft.
...should float like a boat across the water :lol: :roll:

[Doc Tari]

I like the dart board idea. You could do the inside of your 110 in an Irish pub theme. Let me know when the pints of Guinness start flowing and for Pete's sake, keep the kegs wrapped in cork to keep them cold!

There is a guy who lives close to me with a bus company, he owns about 50 buses. I asked him what the bus companies and manufacturers use as sound insulation (I was thinking if they had some cool product I could buy it from him pretty cheaply).

Turns out what the bus companies use for sound insulation is... Plywood.

Yep, about an inch of plywood for the floor, and about 2 inches above the engine if it is a particularly noisy one.

[Doc Tari]

So, did you ask if he would give you a good deal on the plywood?

[rayhyland]

figured if am going to go that route I will use coconut wood.

Hi Dave
Guaranteed to work

I have the ultimate solution for you, in regardes to sound proofing and insulation. This will keep you warm in winter and cool in the heat of summer, as a bonus it is also quite. I have a 1992 Range Rover for sale.

Let me know if your interested?

Obviously for "Pete's sake" only, you yanks and your ice cold beer :roll: :occasion5: :boxing:

[Landlover]

Hey I was wondering if you went ahead with the cork?

I was thinking of doing something like that (sheets of insulation) then painting over them with 'rhinoliner' type paint...

Cork like this...

It would likely keep wine out too. A potential problem though; in the event of a rollover (touch cork), the fire department might need the corkscrew of life. Seriously though, it sounds like a great idea. Relatively light too I expect. What would stick it on well?

[rezdiver]

What would stick it on well?

Corkscrews :wink:

[waspfarmer]

They make screws out of the stuff?

[Landlover]

well I'll keep everyone informed, I plan to do it...probably stick it on with some very serious adhesive...I don't know, we'll see.

The soundproofing/insulating rubber matting is just not good enough, simple as that. So I'll try some 'out-the-box' thinking...who knows maybe it will be a great success...

Hi I have been told by various series owners that I have the quietest running rover they have ever been in. It is a 1962 Dormobile with the Land rover factory elephant hide door panels and roof lining. I think that helps a lot to stop interior echoing noise.
I have undercoated all the floor panels and the seat box and transmission tunnel with thick brush on undercoating. I also went halfway up the firewall.
This helped a lot,also on the inside of the transmision tunnel I installed dynomat, this is very pricey. It comes in one foot sections and if it is heated with a hairdryer can be bent around corners. It comes with its own adhesive backing and sticks to everything.
One last point and it is the most important one. Park in a dark garage and using a bright trouble light check for light shing through various areas. If light comes through at all noise comes through.
Check the floor boards transmision tunnel seat base and the bulkhead. The bulkheadl had air leaks all over the place.
I use strip dum dum to plug these gaps. it looks proper and stays soft for ever and can be removed from floor panals easily when needed for repairs Good luck Victor

[Landlover]

The dynamat looks really neat. What thickness did you use? And what product, the dynamat extreme or the dynaliner…

also just curious approximately how many square feet did you end up using (I have a 109 so might be similar square footage). On the Dynamat website its $600USD for 72sqft. for the Dynamat Xtreme, but I see it on ebay for $150 for 38sqft


Thanks :D

Hi I used 1/8 inch thick material it was 5 or 6 years ago I can not remember the exact material but it was dark brown in color. I covered the transmision tunnel and the piece directely in front of the tunnel and the part of the floor boards facing the engine. It comes in one foot squares and most auto parts suppliers sell it, just shop around for the best deal.
My rover also has the factory black hardura material over the transmisson tunnel and up the firewall inside the rover. This covers the dynomat which is really very ugly.
Again check for air gaps coming through from the firewall and transmission covers.
Also make sure that your park brake rubber, main gear lever and high low shifter rubbers are in good shape and sealed up tight. I added extra foam rubber to mine to make a really good seal
I have driven my rover without floor boards and transmision tunnel in place and it is UNBARABLE the gears just bang and crash like you would not believe. A lot noise comes from the transmission.
I also have the factory rubber floor mats which are quite thick rubber this also helps.
Good luck Victor

[Landlover]

thanks for the help, I found some good deals on ebay. Now I'll just prepare the Rover (dropping the transmission for repairs) and I'm good to go.

I sure hope my wife appreciates it because she can only stand the truck for a short camping trip right now!

Thanks again!
