Is fiberglass bat insulation a bad idea for a campervan? I think it has a bad reputation here and on the sprinter forum, but is it deserved?
- Some say it will absorb moisture. Any worse than 3M thinsulate? The fibers themselves don't absorb moisture, so it would be the air spaces. Seems like the thinsulate would be the same?
- Some say it will degrade & turn to dust. True or an internet rumor?
