Insulating Enclosed Deck

I have an existing deck that we are enclosing. I plan to put in the fiberglass insulation. Should i also use some isulation on the outside under the siding?

Well Matt, I would. I am a great fan of radiant barriers. It is an inexpensive 1/4" thick closed cell foam with foil on both sides, comes in various lengths and rolls 4' wide. You can fasten it with a staple gun. It adds an additional 14.5 R value and reflects 97% of radiant energy. It is also a vapor barrier and will not mold or mildew.

I hope this suggestion helps with your project.
Thanks for listening.
