Extra sound deadening??

What sort of stuff did you use and how much did it reduce the sound by? I want to cover most of the interior, looking at not exceeding 15kg as I know the heavy stuff works better. I was mostly after a rattle free interior but want to refine things more now and make for a more relaxing time driving. Still going to keep the asts though

Dynamat superlite or 2mm Noico stuff. Both decent but the Noico stuff is a fraction heavier

Around 20kg of silent coat sound deadening.. I then put a full coverage of closed cell foam over before putting the interior back in as the closed cell doesn't really weigh anything.

Didn't make as much difference as I'd hoped but still an improvement, wouldn't say it was worth the effort though.. Better to just accept a clio will never be a particularly refined car lol

Did the wifes barge this summer, used some bitumen type stuff.
Put it on the plastic trim mostly though.
There is a difference in vibration dampening and isolation though.
Vibe dampening makes stuff heavier to bring the resonance frequencies down, isolation keeps vibrations from being transfered.

It seems how Im after will cost about 50-60 quid which Id rather save if it wasnt worth it. But I do want some stuff for rattles I think that will be one of the best things to sort out.
