Shading from the outside is a good way to reduce heat load.
Where is your A/C located?
This is the middle roof escape
My A/C is located under the front side table bench. The A/C also conducts a lot of condenser heat into interior. Parkliner did a poor job separating and directing these air flows. The model A/C unit used in my Parkliner has a slide out washable filter, but no space to slide out. The unit has to be removed to clean the filter.
I already made and use insulation panels for this hatch and the Fantasic vent fan. Velcro strips hold these in place over the big openings in the roof. The vent fan has a plastic housing and so that frame is not a interior high heat source.
The aluminum frame of the escape
hatch extends down into the interior. This frame exhibits the known quality of aluminum to be an excellent conductor of heat. So, I was looking for an exterior solution that would hold up to weather, sunlight and road wind.
