You made that sheet metal box? I'm very impressed. Sheet metal work is a skill.

FYI, vapor barriers are generally a bad idea in the south where air conditioning is in use more than heating. Buildingscience.com goes into GREAT detail on when vapor barriers should be used and when they actually cause rot. This is very much not a one size fits all situation.

Glatt, you're right. That's an excellent resource.

Yes, houses here typically have some kind of barrier on the outside between the stud wall and the brick or siding. Tivek of similar on new homes, mine is older so it has some kind of foil covered board at the lower level where there is brick outside and roofers felt on the upper walls where there is composite siding. I think they let it breath more.

I really prefer fiberglass insulation over the cellulose I have but removing would be a huge mess and I already am creating enough dust!

Glatt, my son asked me where I learned to form and bend sheet metal and I explained that back in the dark ages when I was in high school I took several years of wood and metal shop. In the latter I learned how to use a box and pan brake, how to weld, cast metal and run a metal lathe. I think it too bad that so many schools no longer offer students these courses unless they are going a vocational route.

Oh and on working with sheet metal I learned to always wear gloves. You can get some nasty cuts from that stuff!
