Plan on batt insulation in my small fish room, 16 inch on center. Additionally I plan on finishing the inside with 1/2-1 inch foam insulation board for additional r value. Should I tape seams? Any need for poly layer at any point? Will I need to ventilate if every tank has a tight fitted poly lid or will a dehumidifier be sufficient.
my concern with putting in a exhaust fan is wouldn’t it essentially tank my efficiency of keeping it heated or cool? Small room only a couple hundred gallons.
I’m putting a lot of fore thought but this is one concept I’m struggling to understand. The space is a framed in room in a detached shop that itself is drafty.
