I thought about trying that with a shed and insulate the inside really well but I have too many projects unfinished to try it... I may be reaching out to you " brother " for some pointers and info if you don't mind lol I am impressed though really like it.
Jo, thanks again. I figured you'd like to see the final ( or close to it) product. :tiphat:
dow board (blue) will work but you will have 8 layers to get 4" - PolyISO comes in a variety of thickness up to 4" all real roofing supply stores (not hd or lowes) will carry ISO from 1" to 2.5 as standard stock. 2 layers of 2" will give you R24. It comes in 4x4 or 4x8 sheets it will run about 35 cent a sq ft you can figure your needs from there. the inside of the cooler can be lined with the vinyl sheeting for bathrooms sold at hd or lows and exterior lined with economy 3' wide metal.
