SUperlon has 6mm and 10mm both with and without self adhesive. I had 10mm superlon stuffed inside my door plastic panel, bitumen strips on the metal panel ( you need to take out the weather plastic sheet first), swimmers kickboard on the wheel arch which is atype of closed cell foam too.

basically soundproofing is
soundproofing = sound insulation + sound dapemning

sound insulation - to prevent noise from entering cabin, absorb low frequency and bassy noise ( road noise, other noise)...dampening is to add weight to the metal parts of a car to prevent it from vibrating which could produce hi frequency noise (stones hitiing the chassis, rain drops)

Frankly speaking not sure if there's improvement, but closed cell foam like superlon could mute sound from speaker ( to test a foam's sound isulation property, just cover a speaker with the foam) and water resistant... .. since that wira's already an established model, go get hayness manual to take out the plastic covers without breakign any plastic clips...DIY sound proofing is a trial and error process. take your time to do it.

you could get the superlon from a trader at zerotohundred...i thought both superlon and insulflex are made of same materials.

wow it must be costly to aplly RAAmat to the whole floor..how thick is it? I dun have experience with it. You can always use thiner 6mm superlonby the way.

yes, SA is better and less messy...afraid there will be side effect in the future when the glue had contact with metal.

Bitumen won't melt under high temperature..i apply them under my bonnet too.

if you could practically take out ALL the plastic panels in your car, stuff them with those soundproofing stuffs.

Yes ^^ get a glass wool based mat to isolated the bass from other noise..the one you can get from brothers.

LOL great work there! dang I haven't had time to do the whole soundproof thing..

Did you strip down the dashboard to soundproof the inner firewall too? cos I see ur steering wheel isn't there wow..

The bitumen/tar strip should be applied to the door's metal panel..it funtions better as a dampener..

not bad for a saga lmst..

If I can buy the tar strips from you can?

I used the tar strips under the bonnet too underneath the stock soundproof pad...it doesn't drop I think should be OK...try to get the tar strips for roofing purpose made in USA..difference not much compare to cheaper strips..

Thanks A LOT for the contact...that's damn cheap!! Insuflex or superlon?
