I am in the process of building a general purpose / woodworking shop.

Location - Baton Rouge, LA - high humidity area

Two small 3' wide X 2' high insulated windows facing south very near the top of the walls.

Size will be 20' X 22' (440 sq. ft.) with 10' ceilings.

Walls will be 4" - drywall / R-15 batt / 7/16" OSB / Hardie Plank.

Ceiling will be - drywall / R-49 batt / to open attic.

Attic will be well ventilated with (2) 14" turbines.

Roof will be shingled with Solar Board for roof decking.

Any suggestions appreciated . . . . . would really like to hear from someone living in this climate with a simular sized insulated shop . . . . Steve
