What is the best way of sounds proofing the back of a panel van t5 ??

 

[abingdonboy]

Do a search, there are many ways...

Flashband, Dynamat, silent coat, etc.

As for best, i think that each van owner will have a view on this...

Budget will help you decide, flashband is <0.25 the price of Dynamat, and with less waste. But Dynamat might be better, and is a cleaner look (although it will be all hidden anyway).

I've used both Dynamat and Flashband on my van and my personal opinion would be to not use Flashband as I noticed next to no difference compared with the Dynamat although it was far more expensive but works so much better. If you are on a budget I would go for something similar to Dynamat, perhaps FatMat or Silent Coat. Both of those are available on eBay and are cheeper than Dynamat but are a very similar product.

I'm going for a 100ft roll of FatMat on my next van which will be more than enough plus a load left for a few other things.

Hope this helps mate.

When I first started my conversion I went with flash band. The difference between nothing at all and just flash banding the wheel arches was huge so I stuck with it. No doubt Dynamat is better but is it worth significantly more? With insulation and carpet as well you have a fair bit of sound dampening so go with your budget and don't worry too much about it.

Thanks lots of help !!

Speak to Paul at Classic Accoustics at Telford. What he doesn't know isn't worth knowing.
He's a forum member and can advise and supply kit for far less than Dynamat.

+1 for Classic Accoustics, I used their sound dampening and closed cell foam the van is much quieter now, just need to do the front doors.

Hi I would also like to do some sound proofing as it's so noisy in the back with just the ply lining ,I can hardly hear the radio on the motorway!
So how much is the flash band and where's a good place to get it from?Im very tempted to use this as people are saying its a lot cheaper and also I will be putting carpet over the panels so hopefully this will help.
Sorry to jump in on your thread Matt .
Cheers

The cheapest place to get flashband is toolstation i think (www.toolstation.com), comes in various thicknesses.

Others mentioned can be had on Ebay, or Classic Acoustics...

Hi,
I used HD damping sheets from The Noise Control Centre. Similar to what the manufacturers use at very good prices 1m x 0.75m for 10kg/m = £14.05 with sticky backing.

Ok cheers , yeh just looked at the flash band and it's way cheaper than the other stuff, so would be good to hear off anyone else who has used it? I know it's not going to be as good as the other stuff , but just if it's going to make much of an improvement.

Adam when I bought my van and stripped it out it was very loud and boomy. No floor down and just a few bits of plastic panelling and VW roof boards so road noise was coming up through the floor and wheel arches. Rain on the roof would sound like a thunderstorm! Initially all I did was flash band the wheel arches and that in itself was a massive improvement. Added strips to all of the flat panels, roof and doors and even it got better. It was explained on the forum before that this isn't about covering everything to block out the sound it is about changing the weight or density or some such of the body panels so they don't resonate so much sound. I don't know the technicalities but it works. I did completely cover the wheel arches though. If you covered the entire interior with flash band it would weigh a ton more. Once you add insulation and carpet into the mix you reduce the noise levels further.

Would you get better results with specialised materials? Yes I'm sure you would but you will pay more to do it so really you should let your budget decide.

Indeed, I have just put down some barrier material from classic acoustics and have covered the entire floor, front and rear arches, all side panels and it now sounds brilliant, Its a pleasure to drive. The barrier adds density to the panels which reduces vibration which is the noise.

The next step is to add acoustic material from classic acoustics to all side panels and I have some acoustic underlay to go under the ply and then some acoustic backed carpet tiles to go on top of the ply... Hopefully its going to be as quiet as it possibly can be.. Can email you some pics if you send me your addy.

Hi yellow, I had thought of sticking flash band over the whole floor then plying over and finish with a vinyl or rubber type flooring.so now thinking of just covering the section of floor that aren't raised and the wheel arches.
Then like you say just stick some strips on the flat sections of the side panels , I have some celotex and wool to use as insulation.
Cheers
