Hi,
I'm wanting to add sound deadening material to the ancient car as it basically doesn't have any and so is very loud inside. It's design
is a bit odd too in that the front floor and firewall is made of a collection of removable steel panels (for working and removing the gearbox), while
the floor under the seats is thick plywood directly bolted to the chassis.
I was going to get thick felt and cover everything however I keep seeing these more modern stuck on foams and foil backed stuff and am wondering if
that would be an better option or at least to put that under a thinner layer of felt. Any views on what would be the best option or how effective the
foam stuff is in relation to the normal 1/2 inch felt? Budget isn't infinite so also looking at good value for money option.
One of the things that appeals with the foam is that it looks like I can double or even triple it up over particularly noise areas like the gearbox
while still having it in sections to allow the removal of the floor panels.

I'm interested also, but I've yet to get past the endless hype descriptions and DIY users who just throw it everywhere. There seems to be
two primary types - high density bitumen based, and low density. I can imagine the use cases for each, but I suspect I'm missing some knowledge
required to make best use of it.
I have a 370Z - the rear end of it is so loud from road noise that I'm planning to whap some of the high density stuff around the rear towers and
in any of large open spans which may self-excite.
The defender and van I have modified both ended up with a healthy dose of Dynamat. Self adhesive and very dense!! Did a really good job of
stopping panels from resonating.
they have different products for different applications - I used the dense stuff that looks a bit like old school roofing tar sheets (but doesnt melt
like tar does!)
Cheers, I forgot to mention although I'm sure the high density stuff is really effective, I am working with a tiny amount of engine power lol so loading up the car with lots of weight isn't really ideal. Really happy with the condition of the floor though, it's just spotless!
I used a mix of camping mat under carpet and Yoga mat under vinyl mit aged layers of heat mat where appropriate

Ear defenders would be very light weight.

Wooleys Trim offer foil backed sound deadening /heat resistant - not expensive either IIRC

Seen this in the past. Imagine a bit of this placed in the middle of each larger metal body panel would stop the panel from ringing/drumming and cut down the noise when driving (probably wouldn't take much).
Well here it is after a week of work. I actually did quite a few jobs on it in the process like cleaning a painting the floor which fortunately is in
great condition. I bought sticky back foam off Ebay at £7 a roll, 10mm x 2m x .5m. Its the first time I've used this kind of product but I
thought it was just great in every way. Apart from being very cheap, it went on really well sticking and conforming to all the weird shapes of this
floor, plus it cuts easily with just scissors. In particular areas I've even tripled up the layers like over the gearbox and behind the
engine.
I haven't fitted the carpet yet as I've actually painted the top black since the carpet doesn't even reach further up than the tops of
the pedals so hopefully will get a shot later today, I'm expecting a huge difference though, especially considering all the open holes there were
(normal) and the lack of sound proofing before. I would definitely recommend this over traditional felt which I've always used before.
Cheers.
