Shortly I will be insulating my Chevrolet Astro van. I plan to paint the back first where the metal is scuffed up and gouged. Before I add my cotton insulation I want to add radiant barrier. But I have a few questions I am hoping you guys can help with.
Should I go with single sided reflective facing outwards radiant barrier or a double sided radiant barrier that faces inward. I know inward facing radiant barrier will help in the winter, but won't heat coming in from my windows and windshield get trapped inside in the summer too?
Secondly I am stumped on how to adhere the radiant barrier to the walls. I know there are some eco friendly spray adhesives but I would prefer a mechanical method of installing the radiant barrier if possible, would drilling it into the walls with self drilling screws work?
How about if I install it onto the backside of my wood paneling facing outward over the cotton insulation. Would it reduce the effectiveness of the radiant barrier?
