I'm really lost with all the different answers to this question loads of people say Ye use flashing tape and there is the same amount saying don't bother.

I have a mini van which I would like to sound deaden and really don't have a huge budget but a large place to cover.

What shall I do????

HELP!!!

[Bungle]

if on a budget use flashing tape

if you have a bigger budget and want the better job buy dynamat

you get what you pay for

Is there really such a big difference?

How about flashing tape with a good sound proofing foam over the top?

[conlad]

Big difference...

Just buy a cheapo version of dynamat... Silent coat is great like this http://www.ebay.co.u...=item2c64ff9dfe

Something to note with deadening, 100% coverage is not needed, in fact 25% is sufficient. Look at silent coat, it's just as effective but cheaper.

Dynamat is not a dense as flashing tape, however, the main purpose of sound deadening is to stop resonance through the panels, or boom.... Flashing tape does this very effectively by adding weight to the panel, Dynamat does the same thing but is more of an acoustic solution. IMO...

The difference comes when you can do a whole car with flashing tape for the same price as a few sheets of dynamat

Ok so how much should I use and where should I cover with how much

Is it worth doing the whole of the floor with flashing tape and then wheel arches and patches on the side and roof with silent coat?

What about the foam stuff like this stuff http://www.deadening...tor-8-pack.html do I go over everything with this or acoustic carpet?

my car is fully flashing taped and ill tell you know, its bloody awesome!
my car is silent on the inside even with a weber under the bonnet :)

As said already. flashing tape is basically a 'mass loader' to add density to a panel, where as Dynamat and silentcoat etc do more than add mass they turn vibration in to very low level heat.

Flashing tape will do the job 'to a point' where as deadening sheet are designed for the job,

[adamjohnson1990]

So on a budget do you think a mix is a good idea?

So do I just put a couple of sheets in the centre or cover the whole lot?

[freshairmini]

What I would do is get some decent sound deadening (silent coat, dynamat etc...) in a small amount to start on the important areas. You can get a small pack of the 2mm sheets for like £20 ish ( http://www.caraudiod...t-door-kit.html ) it'll get you started. Once more fund become available do more.

From personal experience, I found flashing tape to be quite literally, useless.
I've now gone with silent coat. Does exactly what it says it should.
IMO, do it right first time round.

Just to ride on the back of the original question here, is Silent Coat water resistant? I know Silent Coat Isolator and Absorber are but it's the aluminium backed damping material I'm interested in.

Yes it is.

That's a nice quick answer, thanks for that!
