I have a question or two on a pole barn I'm about to build.
I've seen a few pole barns and they all seem to use double 2x6 pressure treated bottom skirting boards, Why is this?
Before I have the floor poured, do I bring the sub-floor 4" below
the bottom skirting board, so the concrete is at the joint where the two
skirting boards meet?
When I erect my trusses and install my roof purlins, should I install the purlins face down on the trusses or place them on edge?
Do I need to stagger the roof purlins, since the longest 2x4 purling will be 16ft and the pole barn is 32 foot?
Thanks.
