Dynamat insulation on VW

Yep on the pan, firewall, doors and sides.
Great stuff.

yep on a type 3
2 bulk packs 👍

seen this stuff before,and it really excites me.😀
Looks terrific.Diffidently thinking about it for the kombi.👍

Can you still get Dynamat Blue, the spray on stuff?

After having seen the difference this stuff made in a mates car, I'm definitely keen to give it a go in my project. Looks like its the biz 👍 👍

do it.. i used peel and stick on the bus..

is this the sound deadening product? how much did it cost to do floor,walls, doors and firewall?

I hear its very expensive....??

but they use it a lot in the USA...

Really good soundproofing..

you get what you pay for.

yeah there is a fair bit on ebay i just looked....bout 150 for 3.35sq/m

yea there is also a brush on and spray on type i noticed....but i think the beauty of the dynamat is that it is really thick so it works better....i believe it is a tar or rubber based product...it is mainly used for car audio systems but it also reduces road an engine noise.😊

i would of used about that in the end when i did my bug years ago. well worth it.

My Son is doing his 61 Kombi at the moment...

its very thin... and heavy...

He bought a box of it... and will need another box...

its too heavy .. for Me...

You don't need any extra weight in a beetle or kombi...

Lee

Thats how it works, by adding weight to sheetmetal it stops the vibration/drumming effect.

People make the mistake of covering every square MM of paneling when its been said by dynamat it only takes about 25% coverage to give good results

Absolutely true. If you want good sound deadening, the proper way is to use a small square of Dynamat or similar (it's a bit overpriced for me) in the middle of each panel covering about 25% of it, and then cover the whole thing in sound-absorbing foam or felt. This will be cheaper and lighter than an all-Dynamat install for the same noise reduction.

yep thats it i was speaking to a guy today who has it in his car for car audio stuff and he puts about a 30cm x 30cm piece behind a speaker in the door and then uses sound absorbing foam for the rest.... he also has put 2 30cm x 1m strips on floor pan to try to minimise road noise.....i think if you were to put a large pice on the wall infront of engine on a bug it would make it alot quieter....

Anyone intersted in a local, cheaper alternative? I just started speaking to an Oz company who make an equivalent. They have been making it for a slightly different application, but its more or less the same stuff, just a damn site cheaper.

I have offered my car as a test bed, but it still won't be ready for it for months.

But if you guys are interested, add a note here and I'll let him know people want to take a look.

Yes please, I think most without it would be interested especially if it's a cheaper alternative and does the same thing.

Kev

yeah i would be for sure. cheers

There are plenty of cheaper alternatives. Jaycar list some in their catalogue, as do most automotive carpet and trimming shops. Also, apparently some types of roof flashing tape are very similar.

Hi i did some researh about prices and dynamat is very expensive to do whole car, eg guy here in adelaide paid $3500....for his combi . Well what i decide i bought some that thin stuff that goes in roof and i am going to double folded and use that on floor and then carpet on top of it... My trimmer has given me that advice, hope to get it all done and find out how much quiter is but i am sure it will be quiter..

Details would be good

Times like these i love working in a hardware store and getting 20%off as staff discount haha.😵‍💫

if u buy it at that discounted price u could sell it to us for 10% more and make profit whilst being chceaper than the retailer :P...

bajachris88 wrote:if u buy it at that discounted price u could sell it to us for 10% more and make profit whilst being chceaper than the retailer :P...

Get Rich Quick Scheme haha

Just an update. I am chasing up more details on the local material. But the more interest you guys have I.e more posts, the more I can oust them. These guys make stuff for other applications, so it's just a matter of a samll mod tho their production process to make stuff for cars. Th36 may also have something we can use off the shelf. Stray tuned and let me know if anyone else is interested.

Just had a quick look around. alot of guys use flashtac (that is the roofing one).

Well, I am ready and willing to lay down cash before the end of this year for vibration damping and sound insulation material for my S-bug, so I'm interested in any good deal which an Aussie company can make me. I'm definitely not going to waste my money on the Dynamat brand name, at this stage I'm looking at the Jaycar stuff, but give me some details and I'll be interested.

Guys, I've spoken to my guy and he is keen to get something happening. We have the dynamat specs, but does anyone have a small sample of dynamat they can send me? Just an off cut will do, couple of square centimeters perhaps? If so drop me a PM. Cheers

OK an update. Dynamat Exteme, ebay price example $215 per 3.35m2, which equates to over $60 per sp meter. see http://cgi.ebay.com.au/DYNAMAT-Xtreme-Bulk-Pack-10455-9X-Sheets-36SqFt-3-35m2-/180584710907?pt=AU_Car_Parts_Accessories&hash=item2a0bb002fb.

Using this material, http://www.acoustica.com.au/acoustiflex.html as the base and sandwiching between layers of aluminium foil, it looks like the price could come in well under half the price.

The first production run could be before the end of the year.

Anyone else interested?

Hi
THE main objection I have is the weight of these products..
= VERY HEAVY...
I bought a piece of rubber backed stuff from Jaycar a few years ago.. was very expensive.. but also was much too heavy..IMHO

I ended up using the blue yoga mat stuff [foam]
its water proof - weighs nothing and is very inexpensive -

I put two layers over My roof... in quarter panels etc...
around the engine bay- above the gearbox... etc..
in doors... under guards... under rear valance..

My silver beetle doesn't get hot inside it... excellent...
even when parked in the sun....
its very quiet - I've been told by other beetle owners...

I used contact adhesive - from Go Lo..
coat each surface with the adhesive... let go touch dry...
then place together... this is the hardest part.. as when they touch... You won't get them apart....
put it together when not dry and it will probably fall off in the future.... same as when done with carpet using wet adhesive....

ok lee. heres some figures for you with a type 4 motor and the rear parcel shelf and front foot wells done in dyno mat. my car is just under 900kg. the difference in motor is only about 20kgs at the most once converted to upright.
ok a 72 sbug came out of factory at 1918 lbs (roughly 870kg) from here
http://www.1302super.com/b15_72.html

so at 10 kgs of extra weight added and a huge reduction in noise inside the car. i think its worth it.

Like Barls said, people splitting hairs over 10-15kg of sound deadner is rediculous, its no different to having 1/3 tank more of fuel or a very small child in the back seat.

lee dyno mat is more like a tar based product with a heavy foil backing. its self adhesive so no need for gules.
not like what you describe

Hi
Barls
I did see it last week for the first time
My Son has used a box of it on His Kombi...
and making it self adhesive is another plus...

I used some stuff about 5mm thick under the bonnet of the Lancer I had... it wasn't really flexible and didn't stick too well either... as it all fell off... after a while...
not sure where I bought it...

cheers

Dynamat use butyl rubber as their core material. Sorry it's the materials scientist in me.

The local stuff I am looking to have made is PVC based, so a bit different.

Definitely interested, as have already spent a lot on soundproofing car but still need more due to rear cannons being so bloudy loud. They do sound good in tunnels though, and it is cool when I set off car alarms driving past.

Cam070 the acoustica is the bomb better and cheaper than dynamat use it with contact adhesive.
Angel mat is also excellent for engine bays and is chemical resistant.

Whats the production run you are talking about with self adhesive will that be a new acoustica product or something you are doing?

Flash tac should not be used under headliner as the adhesive is not great and the bitumen based deadenert
can melt on hot days!

Have a look at Raamat email the supplier he will send to Australia its also the bomb and half the price of dynamat.

Waltermitty, too dam distracting reading your posts. They take twice as long as they should cause of your avatar!😍

anyone used this?..found it at bunnings...sounded good...my trimmer thinks dynamat is over priced and not as good as most of the others...

FAQ Q) What is radiant heat and why does it matter?

Radiant heat is energy. Radiant heat is heat that is transmitted from a heat source through space. It is the heat we feel from distant objects like the sun or a fire. Radiant heat is also called infra-red heat or infra-red energy. A whopping around 80% of the heat transfer in your building envelope is via radiant heat energy, which heats up the house in summer.

Q) How does Green Insulation™ work?

Green Insulation™ products are made up of layers of air bubbles sandwiched between 99+% pure aluminium foils. It reflects back 97% of the radiant heat to achieve thermal comfort inside home all year around. The Reflecta-Range™ patented coating protects the products from corrosion, oxidisation and glare.
Q) Does moisture and water vapour affect Green Insulation™?

Green Insulation™ products have a unique polymer coating on top of the aluminium surface, which is an excellent barrier against moisture and water vapour.
Q) How do I install Green Insulation™?

Green Insulation™ is easily installed and all the installation guidelines can be found on our web site. Click here.
Q) Does Green Insulation™ pass the fire test?

All Green Insulation™ products pass the required fire tests allowing it to be used in all buildings where AS/NZS 1530.2 & AS/NZS 1530.3 is a mandatory requirement. Green Insulation has a low flammability Index (≤ 5). Please click here to download fire certificates.
Q) Additional benefits using Green Insulation™?

All Green Insulation™ products provide thermal comfort all year around. Green Insulation™ has excellent R-values, fire properties, acoustic properties, tensile and burst strength, fall arrest properties and anti-slip properties. Its entire product range comes with 15 year long warranty.
Q) What does Total R-value mean?

Total R-values indicates the thermal performance of insulation system. It includes the individual R-value of product, air-spaces and building material which are part of the system. Higher total R-values reflects better thermal performance of system.
Q) Can we achieve higher R-value with bigger air-space?

Yes, higher R-values can be achieved simply by increasing the airspace facing the product.

Q) What are different types of heat transfer?

There are three types of heat transfer: Conduction, Convection and Radiation. Radiation is the major form of heat transfer responsible for temperature rise in building during summer.

Q) Do Green Insulation™ products comply with Australian Standards?

All Green Insulation products do comply with Australian Standards of Insulation material including Fire and R-value calculations.

I agree with Lee, the weight of Dynomat concerns me too.
10 - 15 additional kilos sounds excessive, in an 820 kilo car, that has less than 100 HP @ the rear wheels.

I've used flash tac in mine and it has muffled the sound a bit. I did use it in the head liner though and haven't subjected it to extreme heat yet. Thanks for the heads up!

I don't know how much cheaper it has been using flash tac, as I've used 3 rolls from bunnings and spent roughly $150 on it so far, only covering the roof, doors, rear quarters, rear firewall and under rear seat areas.

When you cruise around with the windows down, it kinda makes all that effort redundant. I just upgraded the stereo, so that kinda drowns out the engine noise and encourages more performance from the driver (I turned into a tail gating arsehole yesterday, and I blame Elvis Costello not wanting to got to Chelsea).

I read an article in a magazine years ago that suggested an alternative to Dynamat.
They said go to the local wreckers and take out the lining used in all modern European cars. They have really good stuff, the crashies don't want to charge much if at all and you can get buckloads of it. Then when laying it in place make sure to fill all the groves you find in the sheetmetal first to make aflush surface... part metal part body deadening, and then go over the entire surface, that way you get a very neat finish and a very sound prof one too.

UPDATE - Apologies I've not been around too much lately, but thoughht you'd be interested to know that I have in my possession the pre-production samples of the Acoustica material. It looks good. I asked them to sandwich the butyl rubber sound insulation in between foil layers, but its not as necessary as is the case with fibrous materials as it won't soak up water.

Bottom line is the stuff looks good, has a proven record in commerial applications, and they can produce it for us in 1300x1300 sheets and can definitely make it for people like us.

I can't get pics sorted out until the weekend, and get get that organised to show you all.

I'll then see if I can confirm pricing, but as mentioned before, it will be around half the price of Dynamat, based on ebay prices.

The only catch is they can't put make them self adhesive like Dynamat, but have recommended a 2-sided tape to use with it that has high temperature stability, so should be good for interior/roof applications.

I'll be interested in the acoustica car product if it becomes available within the next month or so, otherwise I will have to hurry up and buy something off the shelf before I go completely deaf. Starting a new job in January and will need to commute in the bug at this stage, so it will need some soundproofing!

dynamat is awesome! chucked some on the doors when i got my speakers reinstalled on my doors. works a treat! makes the doors nice and heavy and really absorbs the impact of thumping speakers.

Camo, how's the Acoustica stuff going? I've got cash in hand and I want the sound deadening in my car before Christmas! I'm on holidays now so it's the perfect time to do it. If it's possible at all to get the product to me before the end of the year then please let me know where to send my money and I will buy! If not, then I will have to use other alternatives.

Been doing a bit of research on sound in cars and from what I can glean, most of the noise is revirbaration of body panels.
Like many I think dynamat is too heavy and expensive and on looking at alternatives, am focusing on rubberised tile adhesive.
I have used this water mixed powder on floor tiles and remember it remaining flexible.
I will be trialing re aplication, colouring, and finish and mixing with ceranospheres (thermal barrier).
The best part is it's about $35/20kg bag.

HI
WELL, I RECEIVED SOME VW PARTS FROM THE USA THAT A FRIEND WAS HOLDING FOR ME.
THE BOX HAD A PIECE OF THIS GREEN TYPE OF INSULATION YOU ARE TALKING ABOUT..
ITS SILVER BOTH SIDES... AND TOUGH..
THE INSIDE IS PLASTIC BUBBLE WRAP LOOKING...

ABOUT 5-6MM THICK...

AND THE BEST PART....

IT WEIGHS NOTHING .. HOW GOOD IS THAT??
NO BRAND NAME ON IT THOUGH...

LEE...

Apologies guys, things have been pretty hectic here. But as I said, I had the sample and the Acoustica guys can make this for those who want it.

Here is a pic of what it looks like. I peeled some of the foil back so you can see what the inside sound insulation looks like.

and here it is side on so you can see the thickness. As you can see its about 2mm thick. And also FYI you need some density or weight to stop/damp the drumming that comes from thin car panels.

and here it is showing that it can be bent to follow the countours of panels, floors etc.

On that link it looks like a product called Aircell, it's like a realy tough bubble wrap with a reflective material on each side and is used in domestic and comercial buildings to insulate under the roofing material, cant realy see how it would stop noise though, the same company has a new (er) product which is a sheet foam, available in a couple of different thicknesses, covered with a reflective material, it's often used in domestic steel sheds and simmilar structures, that may have a sound deadening ability if glued well to the metal panel. I use offcuts of the bubble wrap one under my 2 man and 1 man camping tent, certainly makes it more comfortable by stopping the cold from the ground penetrating into the tent, also acts as a ground sheet to protect the floor of the tent, bit bulky to strap to the backpack though.

Dynamayt is not a sound prooffer its a deadener it stops resonance. The air cell green stuff will be useless on a door panel for noise reduction .the weight is needed so that the inertia of the mass counteracts the drumming or resonating of as car panel.

Camo if i want some do i speak to aucoustica? if its half the price of dynamat I am in the need of some now.
That green aircell stuff will not help car noise.

Don't buy Dynamat. Just cos the Yanks import the stuff to Oz there is better and cheaper out there.

It's OK stuff but far to up it's own arse to justify it's pricing.

Do some research people and save yourselves oodles of cash 🙂

Just to throw another product into the mix, I found an ad in Street Machine for Tru-fit carpets & they have Resomat sound proofing. It is suposedly used in the Queens Bentley & the U.S. prsidents Caddilac & his helicopters. It says it reduces drumming, etc and replaces PVC and bitumen products. 3mm thick withindustrial grade self adhesive. You can buy it tiles ( 490mm square) for $13 each or 3.6 sq meteres for $175. They also have interior firewall insulation, heatproof sheeting & underbonnet noise absorbtion pads which my Dad used under the bonnet of his modified FC Holden and with the bonnet shut most of the engine noise came thru the grill. The picture also shows Resomat molded to the floor shape of an early Torana. Since they do molded carpet they may be able to do it it in 1 or 2 pieces for the floor pan. Anyway you can check it out at www.tru-fitcarpets.com.au

Pardon the language but F**K ME that stuff is excellent value for money and if it does anywhere near what Dynamat says it does then it's a winner in my books.

Cheers for finding that link mate 😀

So,
from what I can tell there seems to be three main manufactured 'products' in use by AVD folk.
Dynamat, Resomat and an Acoustica product.
I can see from the thread that waltermitty has done his kombi with Acoustica. I am sure that other folk have used the other products.

What sort of noise reduction (wind/road/vibration) has been experienced - I don't need exact measurements, just peoples thoughts.
How about just a measurement of 'I no longer have to have my stereo up at max to hear it over the engine', or 'I can use my mobile on bluetooth without yelling.'

Has anyone done a beetle with any of the three products? Which product? What panels did you do?, and how much of each panel did you cover ? (1/4, 1/2 or almost the whole area), the roof?
That way anyone thinking of getting some can work out roughly what area was covered to look at how much product should be bought.

And aside from the cost for the resomat, which is shown above, roughly how much did it cost you to buy and apply (also if you had to go buy your won adhesive glue/spray) either of the other two products?

I have tried to call Dan, from Acoustica, for three days and can't get him - does anyone know if he still works there? Does anyone know which Acoustica product is the better one for cars?
The woman I got on the main switch put me through to sales who thought of at least two products but weren't sure which one was better for a car!!!!

Penguin,
The aCOUSTICAR is every bit as good as the Dynamat. As for cost I couldnt sy I was sent a roll to test and feed bacck.
Results are excellent remember these products are dampeners nort proofing and as such they are excellent for reducing resonance and drumming of pannels.

I had enough product to do all but the roof here I used some compressed rubber sheeting from clark. it is weighty and about 3 mm thick it also does an excellent job and for 20 a 1,2 x 1,8 m sheet VERY Cost effective.
Also be aware that the roof of a car gets very hot so adhesion is important you dont want your tar based flashmat products falling of and onto your new headlining! Also some products are more stable than others which can cause odor problems with heat see Clarks high density foam as not for roofs.
Mitchell

Ta Mitchell,

so the products name is Acousticar 😎 was confused when I rang them the other day and the guy really didn't know what I was after.
I know they aren't sound proofing, I don't even have that with our new Golf - just want to deaden the noise a bit.

I was worried about the roof with a tar/bitumen based product due to heat etc. I was thinking of just horsehair again instead, but maybe the Clark rubber sheet will be the better option.
Did you have any issue with putting standard carpet over the top of it or did you go for a custom carpet set? I am guessing that 3mm really isn't that big a difference for a carpet kit.

If you talk to Daniel He is the production mamger I think. he knows what it is I suggested calling it acousticar but dont know if the name stuck?
I only used the clarke product on the roof under the headlining its very good its like %80 as good as the dynamat acoustica bit %5 price.
As for the floor I have the acioustica in the cab but I have not attached it I dont like the idea of gluing stuff to the floor for rust reasons.
The Trufit carpet heavy duty underlay with bitumen shield is the go i think thier other products look OK also check out their site.
http://www.tru-fitcarpets.com.au
Mitchell

Ok people - I work for the Australian importer an distributor of Dynamat. I've been through the posts and would like to clear up some things.
1) Dynamat is a buytl rubber based product
2) Dynamat is designed and tested to withstand the heat of firewalls and roofs.
3) Dynamat is self adhesive - and again - tested to withstand the heat without falling off.
4) A usual 3.3m2 bulk pack weighs 9kg
Dynamat cost's more because of 1,2,3 and 4.
R&D and freight cost money.
Shops are also allowed to make a profit. That's why they're in business.
If you want to try another product thats cool - But the reason places like Das Resto, Oz Rods, Ziggys, and Bus n Bug use Dynamat is they do not want to have to strip out the whatever and do it again.
Am I feathering my own nest? Well, I don't do sales - I'm the tech and get no commission. But I have spoken to some of our customers who have used other brand name products and now will only use Dynamat.
Doing that job twice if whatever you use falls off is a real pain, and you will wish you paid extra to start with.

I'm afraid you'll never win me over on dynamat. It is overpriced IMO with other products doing the same 4 reasons for much less. For an average DIYer the other butyl products will do a grand job.

Please share the names and RRP of these other products. They would have to be as thick, self adhesive and easily available of course.

The acousticar product satisfies 1, 2 and 4 on your list is just as thick and 1/2 the price. I dont mind rectifying 3 for that sort of savings. Mitchell

acemarc wrote:Please share the names and RRP of these other products. They would have to be as thick, self adhesive and easily available of course.

I think Walter just answered my question there. Please don't get on your high horse about a product you endorse. there are many testimonials on the interweb, if you care to use it, to show that there are other products as good as dynamat.

many unfortunately are not easily available in Oz as Dynamat were able to get in the Oz market early with the finances available to them to do so but many other European and USA manufacturers do not see Oz as a viable option due to small demographic size of Oz.

I think is was Mitchell that provided a link earlier regarding sound proofing and deadening and the research that has followed from this. From what I understand, accousticar uses a different technology to Dynamat - Accousticar uses Mass loaded vinyl (MLV) rather than Butyl. I believe MLV has better sound proofing qualities than Butyl but requires a foam medium to isolate it from the chassis so it doesnt resonate with the body of the car.

If I'm right in my assumption that accousticar uses MLV and it is also cheaper I think with it's advantages is a fay to compli.

Waltermitty - please change your Avatar -it is offensive

Apparently not.
I was put to a vote a few years ago and the menbers overwhelmingly voted to keep it.

Norbert, you may want to check this. While I can't confirm, I think the Acoustica product uses butyl rubber.

Correct Cam. M

OK, must have read another product and thought it was accousticar. Sounded good though.😊

I did check tricot product from them web site, look good to me and also good price. Any comment?

Sorry guy.I mean trufit!

As in true fit carpets? Don't they sell resomat? Seems good stuff and I'm either this or acousticar. Price may well win on this one and the fact the Queen uses it 🙂
