Insulate Berlingo roof

Hi guys,I have music gear in my van and the roof gets damp inside and drips,would the silver insulated rolls of foil sprayed in with glue help?, heard about a layer of aeroboard and to hin sheet of hardboard?.All comments and suggestions welcome

Perhaps if you could get your hands on an old swimming pool cover.
I saw this done before in an attic. It was doing such a good job the ceilings were starting to sweat so it had to be removed.
Nice and light weight to install. Possibly able to stick it to the panels using tec 7 and not lose too much space.

Changing the roof panels won't solve the real issue.

Have a look at the seals around the door etc, are they old and possibly letting moisture in?
Do you always drive with the AC/heating on?
Do you have dehumidifier in the car?

If a berlingo . New type. The only solution is a dehumidifier. I have 2 Aero 360s in the van cabletied to the bulkhead . Works a treat.
Insulation won't do anything to solve the problem . Humidity is the problem . Condensation is only a symptom not the cause.

Would help with road noise though

It would.
But won't stop the damp

Ive seen companies offer a van paneling service with roof insulation?.

It would work. Did this on the Transit camper. Obviously if the van is damp it’ll condense on the cold roof, and that should be addressed

We used silver bubble wrap type stuff stuck on with contact adhesive, few small batons across and a thin ply lining over that. Used rock wool type insulation in the gaps and covered it with veiltrim interior carpet.

Obviously be careful that you don’t screw through the outer bodywork.

Maybe look for a crashed Berlingo multispace and transplant the rear headlining.

Exactly, when then environment outside becomes cooler i.e. at night, the thin metal in the roof quickly cools down. When the temperature of the roof is lower than the air inside, the extra moisture in the air condenses on the underneath of the roof. The result is the roof sweating and dripping water. Since warm air rises in the van, the warmest and most moisture laden air is at the roof, this is also why the roof sweats and not the sides.

So there's two options, add ventilation to the roof or remove moisture from the air.

Or make the surface that the air actually hits warmer. Like in a car.
