Instead of grabbing the pink insulation, grab the roxol brand. Same isle at home depot. more sound deadening and water flows right thru it.

3M Thinsulate(TM) acoustic/thermal insulation is hydrophobic, engineered for use in vehicles and passes all pertinent Federal Motor Vehicle Safety Standards. PM me for a sample.

IMO, giving the "all clear" signal to a newbie asking about fiberglass insulation is doing them a disservice. Many will say, "sure go ahead and use it (and leave off the "sucka!")" but once you burrow down into the subject, you'll find strong sentiment against it. What it has going for it is that it is cheap. Even Van Specialties uses it in the custom vans they build but they are in the business to make money. Here is a worthwhile link to read with an excerpt on their take about fiber glass.

Batt style fiberglass is used quite a bit for conversion van insulation (even by commercial converters). *On the plus side, it’s very available and cheap, and fairly easy to install, and its also easy to remove. *On the negative side, it readily allows water vapor to pass through it and this promotes condensation on the cold van walls and potentially leads to rust and corrosion. *It is also not viewed as a particularly healthy product to install, or to live with long term — all the bouncing around that a camper van does may lead to fibers in the air for a long time.

I have also read stories by people updating a conversion done on an older van in which they removed old fiberglass insulation to find quite a bit of rust on the van sidewalls. *I don’t think that this is common, but it does happen.
Most people who have looked into insulation for vans reject fiberglass as a choice, and I agree — I’d go with something else.

Another product that is not affected by moisture (unlike fiberglass pink) is polyester quilt stuffing. It is inexpensive and available at your local discount fabric store. I used it to fill the upper and lower wall cavities and the lower door cavities. It's nicer/easier to use than Roxul.

Another item that I never seem to see mentioned about fiberglass insulation is the stated R-value is compromised if you "stuff it" into spaces. Fiberglass R-value is decreased if its width is compressed.
