it's sound deadening it's not just about panel drum/ road noise . Your' ll be trying to sleep with your ear is right next to the outside panel. Anything you can do to keep outside noise away and your Snoring inside plus a 2nd foil barrier to reflect heat away off the foam insulation then the fluffy wool insulation stops / fills the gaps and voids to help stop Condensation Building up behind your panels. with screens over the windows help dampen noise there
worth every penny and it helps keep the van cool or warm as a bonus
just add the cost to your resell bill whats £ 300 if you laying out £37,000 on a conversion ... well £29,600 + VAT lol
its worth 10 times that if it blocks out all them xmas tunes pumping out of your sub woofer lol
Thanks for that. The financial side of it is a no brainer, I was just interested in why most convertors don't bother. Seems like there is no answer to that!
