HardieBacker Cement Board for Closing Bottom of Porch
I need to close off the bottom of a porch. Normally my go-to would be pressure-treated plywood, but it’s running about 75 bucks a sheet these days. My local big box has 4×8 sheets of 1/4″ Hardiebacker for $21. I think it would be pretty good for this, it’s tough and impervious to the elements. Nothing is going to chew through it. My only concern is it might be a bit brittle.
