VW T6 camper roof top insulation wrap

Deggerz

We have a T6 which was converted to a camper van with a pop up top.  When camping in the rain the sides of the pop up top get wet.  I’m therefore looking for an insulated/waterproof wrap of which there seem to be a few available. Has anyone used one, had experience of using one, or know of anyone who has one?  Any bad or good reviews would be great.
