This radiant barrier worked perfectly for insulating my #CLCTD #CLCBOATS camper. I glued wood blocks with holes to the inside of the teardrop camper. I cut the insulation into panels that would fit the interior of the teardrop. I used spray glue to attach my chosen fabric to the insulation. Then I used a nylon, press fit connector to hold the fabric covered pieces in place.There is a small air gap between the insulation and the inside surface to the teardrop. This allows warm air to flow to the exhaust vent on the top. The system was tested for 99 days with no condensation with a temperature range of 37 to 90.As a side benefit, the acoustics were awesome!
