Hey guys,

Been working on the van since getting it (mostly mechanical stuff) but as of late I really want to cut the noise down when driving and also making a start on insulating the van.
I've already started with cutting down noise with new window seals and such which have helped a lot, however I want cut down on panel boom and road noise next.
Currently I am only planning to sort the front out out as I don't want to strip all the interior out with the crappy weather and short days, ( plus I have nowhere to put it all at the moment! ).

I've been on sites like deadening.co.uk and picked up a small pack of the Silent Coat mats to give them a test, While they do cut down the panel boom noise, as someone who is on a budget (aren't we all) they are quite expensive for what you get and I was wondering if there is a cheaper alternative that anyone may have found?
Ebay lists a metric ton of different suppliers and manufacturers of similar products and I am not sure how much of a minefield it will be as I don't wanna be buying stuff that's gonna cause me real headaches in the future.

My thoughts are to use sound deadening mats in areas to cut down panel boom and then put a layer of insulation over the top, as it's going to be on the floor in the cab and between the seats I am trying to find a self adhesive roll of insulation material that will be suitable for cutting to size and putting on the areas I need it on.

I get that cheap and quality aren't usually mutually exclusive,I've read through the WIKI but any input would be great if you've done it yourself.

Cheap and quality are available together as waste sometimes.

I am in a similar place to yourself, about to start with the insulation.

So as I understand it sealed cell PE foam is the one to go for,
and it comes mostly with adhesive already on, and paper to peel off.
I have found some various similar stuff around, old yoga mats, sleep mats etc.
Along with some less quality packing foam, and builders protective foam sheets.

The problem I am about to come up against is what glue is best to use?
We will be wanting to glue it to fibreglass high top, door and body panels,
as well as to itself when doubling up.

My first stop would be a cheap silicone, squirting and pasting plentifully,
but this in itself is not cheap, and creates the nasty vapours.

Then looking at some large areas I wonder if its actually cheaper buying new,
no one complains of the adhesive not working, panels coming away again?

You can get rubber butyl based roof flashing/ flashband, as opposed to bitumen based. So no tar involved. I've used it with good success. I got mine from Screwfix, but last time I looked they'd stopped selling it. £22 ish a roll. Anyway, it's mass loading the panels for sound deadening, not insulation, and works well. Look that up maybe?

Yeah the self adhesive stuff is what I've come to look at, mainly due for ease and not having to faff about for glue and things.

I'll have a looksie for stuff like that, cheers. With it being rubber based it might even wear better than the bitumen based stuff being on the floor and all maybe. But it's something to look into

Sound deadening self adhesive matting fitted to the interior of the panel and then stuffed with the following

Only did doors, will do rest when refit interior. Will also do the cab floor and battery boxes at some point with the self adhesive matting.

Yeah that's fine for the cavities in doors / panels as I was going to use that stuff actually. But I am on about doing the floor so looking for options for the mats

Does this stuffing not absorb and hold moisture?

If I recall it's recycled plastic bottles, doesn't retain water.

Sounds good then, as I reckon a fair bit of water must get past the window wiper seals,
and it needs to get down and drain out the bottom of the door asap.
We could maybe also treat the stuffing with a kind of WD40 water repellent.
That would also help to inhibit any potential for corrosive effects of the passing dampness.

To be fair as I plan to fit the insulation to the inside of the doors as snug as possible there shouldn't be many places where water can come into contact with the panel and cause issues. The bottoms of the doors (once welded) will just be sprayed with some waxoyl or other such stuff.

Sounds easy when I say it like that.
