Hi peeps, whats the best value sound deadening material for cars? Dynamat? Any other options one could use? Ive heard of bitumen flashing being used by some, whats current best practice/best value? I want to reduce the sound levels of a VW camper.

I want to deaden the sound of the boy racers who come roaring up the
hill at two o'clock in the morning. In summer with the bedroom windows
open it's not funny.

I'd be willing to try bitumen but I suspect a shotgun would be more
effective.

Best value is probably what I used back in the 1960s - sound deadening
felt, bitumen faced for the engine bay, uncoated elsewhere. Whether it
is the most effective now available is a different question that I can't
answer.

From experience with felt in a camper van many years ago, the problem is
that felt holds condensation.

Ours rusted out from the inside.

Maybe a VW would be better.

I didn't notice that in my car, but it had a chassis, so bodywork rust
was less of an issue and quite a bit of it was glass fibre replacement
panels anyway. Perhaps a high density closed cell foam would be a better
choice.

Well, my camper was Commer Van based, and we slept in it, 2 adults and 3
children. The OP was talking about a camper, and I would think
condensation is something to consider in any of them.

I would think foam would be OK if thoroughly stuck on with nowhere for
water to run and hide.

Bitumen paint is certainly cheap, only gives very limited effect though. Then it's down to foams of various sorts. Beware of condensation though. Chucked out rubber flooring offcuts would work well.

I bought some stuff that was very sticky plastic on one side and lead on
the other. Very heavy but also very effective.

Bill

Yeah that sounds like the stuff a chap used who did some welding for me, also called self adhesive bitumen flashing. Very heavy stuff, perfect.

Is that the air cooled old version?
Yuck good luck if it is!

You need a sound operated device that rasies spikes in the road. After
multiple punctures they would soon get the idea of driving slower.

There is also the stuff made for boat engines. A layer of foam, then a
layer of lead (the expensive stuff) or heavy plastic (a bit cheaper).

It works well for the original purpose and worked extremely well when a
built a sort o sound proofing "chimney" to silence a computer for use in
a studio.

The stuff you see on production cars - mainly to stop panels ringing - is
self adhesive bitumen panels. Peel and stick. A decent car paint supplier
should have them. You'll also see them inside quality loudspeaker cabinets.

I had a couple of the doors on the old Rover re-skinned. The originals had
these panels, the new skins not. Made the doors clang when shut. Fitting
the panels changed it to a more expensive sound. Not cheap, though.

Also, beware of strong side winds which can move an
air-cooled VW camper/combi/van from the motorway
slow lane into the fast lane before you can react.

I was working on a vintage Jag recently. Upon removing the rear seats
(which are the bench type and come out as one unit) there was some badly
deteriorated rubbery foam layer for sound-reduction purposes. It had to
be removed but was too fragile to survive. Rather than source a
replacement, I thought I might just re-fit the bench seat, then spray a
can of that expanding foam into the void where the rubber layer was. Sets
pretty rigid and occupies every cubic CC of space it can find. Might even
be better at noise-reduction than the original? Certainly quicker and
cheaper than trying to replicate the original from sheets of rubber foam!

Self adhesive bitumen sounds like "Flashband", or is it thicker than
that? Flashband is pretty cheap, were you being charged Russ Andrews prices?

It came from a decent local trade car paint supplier. How similar it is to
flashband, I dunno. It does have small holes in it at regular intervals.
It wasn't expensive as a percentage of the job - I merely thought it
expensive for what it appeared to be. But not so expensive as to want me
to experiment with an alternative.

Never been able to figure what the holes are for. Surely not as guides
