Housewraps, Felt Paper and Weather Penetration Barriers

I'm in the Texas area. When I pulled off the wood siding on my house, I found black felt paper. Which is pretty common in this area? Most of it in great shape. I will be replacing the wood siding with Hardi Plank. Do I need the hardi wrap or will felt paper due just fine? What are the pros and cons that I need to be concerned about when picking a housewrap/moisture barrier?

I am also wondering does it matter what side the felt paper is on when installing? White lines up or down?

Thank you,

Welcome to the forum! Felt will reseal the fasteners holes, unlike plastic. Felt will also remove any water on the side closest to the sheathing, plastic won't. Some recommend two layers of house wrap/felt with reservoir sidings like stucco or even cement board, depends if you get a lot of rain, also. Especially bad on the sunny side of the house. Tyvek is better than Typar for the lower perms, easier for water vapor to pass.

Let me know if you need more

Run the felt horizontal. It will help with a good overlap as well as giving you reference lines if you take the time to put it up appropriately. Granted you will still snap lines to run your courses, but the white lines on the paper can be an additional guide.
