Here is my FLORIDA solution to the HEAT generated by the skylights. I made 2 inserts, still need one more. One for the skylight over the shower and one for the ceiling fan opening. They are made of the light rigid insulation board (flexible), from Home Depot. It was about 130 degrees in now you do not feel the heat at all. Although, it does eliminate ALL the light that comes in through them, so the EXTRA BRIGHT LED's I installed care for that problem.
Go with the 2".. for even more insulation. I made them a tight fit and they go in and come out very easy
I still need to put some contact paper on them to improve the looks.
