Skylight cooks RV like a Sauna

I recently purchased a Forester 2401R. There is a skylight above the dinette with no shade on the glass. The heat from the skylight is so intense that it cooks the interior to where the A/C can't keep up with it. Hold a thermometer above the dinette table and it reads 100+ degrees! And that's with the A/C on! I cut a panel of fiberboard to insert over the glass - and the heat warped it in minutes. Then I covered the fiberboard with the reflective screen you see on parked car windshields, and the narrow space between the glass and the screen got so hot in just ten minutes that I burned my hand taking it down. I finally gave up on the design in fear I would set the coach on fire or at least melt the plastic frame. I have looked all over the web for a solution to this and am hoping to find one among you folks.

The dimensions of the skylight are:

Inside frame 30 x 22
Outside frame 33 x 25

I would cut a piece of Styrofoam insulation to fit inside the opening, and then cover the opening itself with a reflective insulator. We do this to all of our vents and skylights when in hot environments and it works well.

Cut it 3 times and it's still too short...

I just take down the interior section of the sky light and cut a piece of reflectix and put it up under the dome that is left and then put the interior section back up.... kind of like a reflectix sandwich. Does wonders!

I once put a piece of parchment paper, the kind bakers use, between the bubbles of my shower skylight. Later i replaced the outer bubble with a dark smoke tinted bubble.

Here's a thread about the replacement with a link (that no longer works) to the source for skylight bubbles of all kinds and shapes. Looks like you'll need some help finding a dark bubble.

FR prior to the 2019 models had a blind installed on the skylights. It is a standard blind as well as a seperate section that is a darker sunshade. I do not believe they have changed the dimensions of the skylight. You should be able to order one from your dealer. The two in my coach work very well.

They do make foam insert that will fit up into the sky light to block out the sun. Later RJD

Paint the top with white paint. Still lets light in and keeps a lot of heat out.

Accordian shade

Does your skylight have a two stage accordian shade on it? It seems to help with the heat but I'm thinking of adding a piece of reflective shade between the skylight and the shade.

Partial solution: 2800 QS Mods

I have been in 90* + direct sun for two weeks now and my single A/C has no problem maintaining 74*F

Edit: If you want a shade, here are some sources:
