Camper Shell Insulation

Bought a used Leer 180 for my 3rd gen long bed. Its currently raw fiberglass on the inside and I am thinking about trying to insulate it before installing the head liner

1. Has anybody tried using the Lizard Skin spray on insulation product?
2. Does anybody have a link to a piece of fabric they would recommend using that comes in pieces big enough to install in one piece?

Thanks!

 

I used lizard skin for inside my truck, its nice, but not worth the price for a camper shell. You would be better off velcroing that insulating bubble wrap stuff to the ceiling.

 

Yes, Reflectix would be a cheap and easy way to insulate. Velcro would probably stick it over the headliner material. I've seen some people use adhesive spray to adhere Reflectix to overhead surfaces and curved surfaces. I'm not sure how well it work work in combination with your headliner. It would be super cool to find a headliner material that was already insulated.
