Quote:I'd be concerned that the stone roof would act like a massive heat sink, they make high end wood stoves out of soapstone for a reason.An aluminum shingle type roof might be a good compromise, it looks a bit like a slate roof and although the metal will heat up it will radiate that heat off very rapidly as the night cools down .Norm
Quote:Just my 2 cents , but it seems like between the roof, the stone cladding on the rest of the house, the stone patio, and the driveway (not sure what material?) you'll have heat radiating out all around you. A little extra stone around the observatory itself won't make much difference. On the other hand, keeping the wife happy will make a BIG difference! -Dan
Quote:You will likely needs several hours if not until after midnight until things calm down. My best option is a roof top observatory but I have not done anything due to the heat sink issue.
