Thanks Alastair, ours is a tin top so may have further benefits.. Excuse my ignorance but underbody,? Drew
Soz, not reading the post correctly, there is a underbody spray on liner called silent coat or similar, my brain was thinking of that...You mean the stick on bitumin type pads? I used cheap flashband ype stuff from Screwfix, was just after something to take the "drumming" noise from panels, wasn't looking for the best stuff you can get for the quietest bus ever, the construction of the bus and the inner panels and lake of soft trim doesn't help, which is why a modern car is so much quieter, aside from the noisy air cooled lump in the back.
I reckon it should make a difference to panel noise, I did make a short video to show the difference bettween a panel with, and without the flashband I used, I cant get it to download to photobucket, and my browser is playing up on the works pc, so i can't view pages with script on correctly, but it is on my Instagram feed if you look, I'll see if I can link it onto this thread (I'll give it go over the weekend)

Sound deadening, yes, propably little insulation effect. You'll need different products to achieve each goal, the sound deadening flashband i used is just one thing. As for insulation, you can see in earlier pages on my build what i used, since i did it, I now have loads of sheeps wool i was gonna use, but may be going off the idea of insulatiion at all behind the panels, as some people have suggested condensation may still form. It's a fair comment, i may look into this again if i get round to replacing the side panel with new wood.....possibly as the flashband is on the inner panel, it may have some insulation properties on the panel, it's not air to direct cold metal, so maybe not as much condensation? If i get round to replacing the wood, i'll post up my findings re condensation.
If you can get to the metalwork on the roof, I would use some sound deadening product there, there is bound to be noise transmitted there - used cheap flashband, or thicker more expensive fat mat or similar. Apparently, you don't need much on any given panel, 25% or so, and you dont need to cover the panel, I did, only as it was cheap, if i was using a better quality product, i may be more aware of placement.
Perhaps use that carpet underlay type stuff (for cars) or maybe even just closed cell reflective foam stuck onto the flashband product would give sound and insulation effects on the roof? Certainly bound to get condensation on the roof, not sure what the factory used, if anything?
In my westy, space amounts of thin (less than a inch in old money) fibreglass insulation were used in small quantities behind the panels where i used flashband you can see the remains on the panel work for the long side panel.
Anyway, it's late, and i still probably haven't read it right, any more questions, I'll reply over the weekend when my brain is more in gear. (I've edited it 3 times already :roll: :lol: )
