We decided to insulate the new porch roof in an effort to decrease the
heat that radiates from the toasty tin.
The plan is to use this as an
experiment to see if we want to do a similar thing on the first
porch.
One downside is the sound of
rain drops on our tin roof being muffled, which is no small thing to
delete. Doing this porch first will help us to determine just how much
of the natural rain drop melody will be sacrificed for a little thermal
efficiency.
