Hi Guys-- Thanks for the ideas.<br><br>Yeah, my shell was just an open piece of fiberglass. I insulated it with 1/2 foam with foil-type stuff on one side, and then a 1 inch layer of polyester batting over that. It's much quieter now, and really insulated. I just need to find a ceiling material now.<br><br>My challenge is that I'm not so handy, so I'm looking for something easily installed. The two things I'm thinking about are either some type of cloth that I can just glue to the batting, or bamboo. Home Depot has this reed/bamboo fencing that I could secure easily to the inner framework that might look really cool. I'm not sure. <br><br>I do want to stick to my eco-friendly theme of non-toxic materials, and thought the reed/bamboo look might be cool. Might be a mess, too...<br><br>Here are pics of the insulation. Sorry, they uploaded sideways... :/<br><br><br>
