I built my 4x4x6 oven about a year and
If i remember right i used 18ga for inside floor, 20ga for rest of inside. 22ga. for outside.

I think i had about $1400 total in it...

i think we used 20ga galvanized... i remember it was $25/4x8 sheet. another local company i called wanted twice that. pffft.

used 22 ga. galv. on the inside, 14. ga. on the floor & 22 ga. on the outside. 2" tube frame w/mineral wool insulation. Dayton high heat blower & this controller set-up. had just under $1k in it & about 50 hrs build time.

I used 24 gauge on everything but the floor. Galvanized sheet metal cost $46 for a 4X10 sheet(best price I could find locally). My inside dimension is 24X30X65 and cost around $650 to build.

I get Johns-Mansfield 1000' oven insulation for $1.06 per sq foot.

i used 4" R15 fiberglass from home depot with some hesitation. i decided to try it because the donor kitchen oven i used for parts used it. it's been working great for about 6 months now. just remove the kraft backing before installation.
