We have spent the last hour searching RV net for information on skylights. Our question involves insulating ours against the intense summer sun here in the south west. the skylights let in large amounts of heat and light and the coach AC really struggles to keep it cool. We are thinking of getting foam insulation to fill them to keep out the heat during mid-day periods but are concerned about the heat build up in them damaging the skylights. The vented ones we can open slightly but the sealed ones (non opening) are a real concern. Can anyone offer any insights? I know CW sells the foam inserts.
Thanks

Reflectix bubble foil insulation is what I would recommend. Foil reflects sun and heat away and bubbles provide a cool layer to the interior.

The skylight over the shower was my peeve. Let lots of light and heat in. They are two layers and you can remove the inside bubble by removing the screws around the molding. Them I cut some of that flexible aluminized foam insulation a to fit and taped it in with aluminum duct tape. Reinstalled the inner bubble. Looks fine, totally balck, much cooler. I also cut pieces to jam up in the skylights/vents.

2" rigid foam board from Lowes, cut to fit and use blue tape as required to hold in place. works well in summer or winter.

Shade cloth over the outside of the skylight can work wonders. It's easy to cut to size, and cheap enough to replace frequently when you forget to remove it before heading out. 
You can find it at just about any plant nursery, and in several levels of opacity.

I use those 12X12 insulated cushions in each of my skylights. They sell them at Camping World for under $10 each. They work great. For the large skylight in the shower I got one of those thick aluminum door window covers at CW. It fits just right. I use Velcro to hold it on and it is easily removed when I want the light to come in.

This also works for us. Cost about $5.00 and makes all the difference in the world......We just stuff it in without tape........
