I don't have the numbers, but a10 sq ft Low E2 window in direct sun

I just did some quick checking

With 900-1050 watts per square meter peak solar intensity and an SHGC
ranging from 0.42 to 0.67, a aquare meter window in direct sun can
provide 450 -703 watts of heat to a room. That's assuming Low E argon
filled double glazed window

I've got a couple of southern facing skylights that I want to add some
sort of protection to. I'm not sure what it will be or how I will do
it, especially since they are 11 feet off the floor. I guess blinds
would be the minimal effort approach, especially if I let someone else
do it, lol. I'm thinking a piece of styrofoam covered with fabric to
make it look nice and seal around the edges. Once side would have a
reflective layer, possibly the reflective bubble wrap stuff. That would
reflect the heat back out and likely work as well when it is cold out,
not emitting as much heat.

With the reflective layer on one side it needs to fold away from you,
into the window well which is not deep enough for it. Folding into the
room means you see the reflector. Also, folding into the well means it
won't seal snug around the edges. Not sure what to do about that.

Trying to make it slide away from the window sounds hard to do. I am
thinking of a hinge with a draw cord. To slide sideways I could use
arms at each corner and swing it away to another spot on the ceiling or
even just let it hang to the side, it won't be in anyone's way up there,
lol. .
