Need some opinions please. I have a 24′ x 24′ detached garage that is presently sided with T111 panels. The T111 on the two sides (not gable ends) has deteriorated along the bottom due to insufficient overhang of the roof. I am getting ready to remedy the overhang problem and replace the T111 on the two sides. Front and back of the garage are fine. I was seriously thinking of using the James Hardie “Hardie Panel” 4×8 siding. It looks pretty much the same as the T111 but comes preprimed and should be much more durable. By the time you figure in the price of primer and the time spent to prime the T-111, the Hardie Panels actually are cheaper.
My big question is … even though the James Hardie web site states that the panels are acceptable as shear walls, I am a bit hesitant due to the thickness (or lack of ) of the Hardie Panels compared to the T111 ( 3/4″) Has anyone done a building with the Hardie Panels alone ? Am I being overcautious ? My plan is to paint the Hardie Panels inside and let them dry, then replace the T111. I can put some temporary 2×4 braces on the insided of the walls to keep them from racking while I am doing the replacement.
Any thoughts, experiences, or ideas are appreciated.
Thanks in advance,
