Observatory Part 10

Insulation!  I am insulating the roof and walls of the observatory to reduce heating in direct sun and also to reduce condensation.  This is just R5 polystyrene and I have installed it rather crudely, but it will do the job and (most importantly) it is very inexpensive. The next step is to install the rest of the studs and to install the drywall to give the interior a more finished look.
