New insulation under existing metal | Ask The Experts Forum

Guest User 12/18/2011	I have bought a mobile home with large metal roofed patio. I would like to make part of this a room. The metal sheets lie on 1x4 at right angles to 2x4 supports. There are no leaks, but condensation on bottom of metal on cold mornings. Can I put fiberglass batt insulation in the spaces and then poly vapor barrier , then plywood ceiling ? Is there a better or more economical way ?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16913/find/
Todd Miller Isaiah Industries, Inc. 12/18/2011	A better way would be sprayed polyicynene insulation.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16914/find/

You would be far better served with spray foam as Todd mentioned. Closed cell will be better in your application.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/16915/find/
