I've researched here and on the internet several items responding to this inquiry.
I see several folks talking about 3" foam covered fake lambswool covers (like you insert into a vent fan opening, 14x14) they install on their skylights. I suspect these must be even square skylights. Mine is domed and I can't see how a 3" foam covers.
I have seen also some folks fill the void with foam in between the exterior and interior skylight.
And further seen some folks put towel rods in and even someone a great idea, a day/night shade that just slid out of the way, no fuss, no muss-nice.
Also a lot of posts about painting the skylight from atop.
All good ideas, but the last post I saw was in 2012 when researching.
Any more/better ideas on how to cut the light/heat when not in use and still be able to have light when showering?
The best idea so far I'v seen is the day/night shade that just pulls out of the way. Mine is 23.5 x 24.5 inches, that is the lip to lip dimensions. It is a bubble type dome so I can't see how the fabric covered foam inserts would hold up.
I have looked at spring curtain rods and making a custom lined fabric curtain for it and still think that's the best idea.
I did also read several folks mentioned that the heat produced from the sunlight is an issue, but in my case I want it covered when not in use for primarily the blinding sunlight in the daytime north Texas summers.
Any new ideas? PICTURES very appreciated folks!
