I have read several threads on this issue and I am now considering painting the outside of the skylight with something like Elastometric Coating.
I noticed that some have had trouble with putting anything reflective in the inside as it creates too much heat and can deform the plastic skylight.
What do you think of removing the inner shell and inserting some Reflectix insulation in between the two shells? I know it would block ALL the light but do you think it would cause a problem with heat buildup? Would this be a good solution?
Thanks for any and all responses!
