There is some concern about using fiberglass insulation in vehicles. Pressure waves from closing doors, vibration and air movement in the walls from driving will dislodge fibers and possibly circulate them into the living/driving space. These fibers are considered carcinogens by some.
I carefully removed some fiberglass insulation that had been installed by the previous owner and had been in my van for a number of years. The stuff had broken down and small fibers were flying everywhere. There was also some evidence of it getting wet but thankfully no mold.
Hi again _hein_ ...
This came up in previous build and with what was discussed there, this insulation job addresses those concerns which I feel are total bull****.. Just being honest...
In the grand scheme of things even if a bit of airborne fiberglass were present, and if that minuscule amount was inhaled, the likelyhood of that messing up your life is so very small compared to just about everything else that surrounds us if we are in a vehicle... Not to mention modern life... In my world the sky is not falling...
Maybe I'm lucky, but I've been doing dusty, hazardous work for close to forty years, nonstop, and that includes a significant amount of time doing a lot of fiberglass surfboard sanding, most of the time without a mast... Imagine a dust cloud surrounding me for years... Decades... Early in my career, at a lumber yard, we cut sheet asbestos board with a tablesaw and no masks... Then there are all the residential and commercial remodels that involved more demolition of nasty stuff for again! Decades...I've also done dozens of acoustic ceiling scrapes jobs and no mask... Back then it wasn't a concern... Then there is the day after day, decade after decade, carpentry, which is basically a constant dust producing activity...
At 58 I feel (and my physician says) that I'm doing just fine... To say that we lead an active life would be accurate, and that is what I think is the primary reason for good health, and genetics... Eat well too...Should I have been better protected all those decades from EVERY potential hazard, sure... Would I feel any better, I don't think so, and I can't change the past...
That said, on this build, a thermal and acoustic foam went against the steel... Over that went the loose fiberglass... Over that, and contact cemented to the steel to prevent any friable fiberglass from becoming airborne, is the double foil faced bubble wrap insulation...
I am paying attention to what's being said here and if I can address those issues even if I don't subscribe to them I will, if it is simple and cost effective, to do it... On the last Sprtiner van I did, the fiberglass insulation was covered with taped on polyethylene (that
sounds dangerous) sheeting to mitigate the potential airborne fiberglass...
If you check out the pictures of the builds since airborne fiberglass became a topic, the only openings are where the electrical cover-plates will be... I'd say it's pretty close to being airtight... Enough not to worry about an imaginary life threatening exposure...
I hope that helps to show I care... 
