Hi,

I'm looking for a way to insulate my metal shed observatory. I've had a dew problem all winter and would also like to assist with heat reduction in summer.

I'm unsure whether a reflective foil type radiant barrier would work. It seems difficult to seperate marketing hype from actual performance. Straight foil seems to reflect 96% of heat and is a lot cheaper than the foil plus bubble wrap..and that bubble wrap stuff doesn't seem any better spec wise?

Opinions please? I've also put in some large vents and a whirlybird...

Just want to make sure moisture doesn't damage my scopes/electronics.

cheers
Gary
