Insulation Inside Panels.
Posted: 27 Aug 2026, 13:31
I've posted here as the camper section has little activity over the last five years.
What's the general consensus for rock wool packed against intervals of bodywork? Some say it hold moisture and rots internally. Others' say it is fine.
I bought this camper two years ago. All the cavities for doors and hatch are filled this way. There are no signs of internal or external rust on any four opening panels.
I thought about fixing radiator insulation to panels using heavy duty carpet glue, then repack with rock wool.
