I know that 'insulation' conversation has been beaten to death but I still have a question! lol I'm planning on using Ultra Soft Denim Radiant barrier in my van. I've seen it used on youtube with the 'shiny' side directly against the van wall. NO AIR GAP! Doesn't this still require an air gap? If I put the denim side against the interior wall with the 'shiny' side facing into the van, would the thickness of the denim (3/8" thick) be enough of an air gap? The plan was to then add a layer of polyiso, then my wall.
Any thoughts? I've already ordered the Ultra Soft so please don't tell me not to use it!!! lol
Thanks.
