So I have a friend that wants a wall erected on the side of his back porch, primarily as wind and rain screen. Proposed wall is to be conventionally framed and sided, to match appearance with the house. Currently two of the four sides of the porch are open, with the back wall of the house and the sun room forming the 2 solid walls. The proposed third wall is to close in the side of the porch and will have Hardiplank siding on BOTH sides of the new wall. This wall will not be structural - just tying into the existing roof and the house wall.
Here's the question: What are the reasonable options for the type of wall board under the siding of the exterior of this wall? It has been years since I have done any 'framing' of exterior walls. Insulation is not important, but keeping water out would be. The plan is for conventional framing, wall board, house wrap, then siding. Is wall board needed here at all, or can the house wrap and siding simply be installed over the framing without any type of wall board? Interior side of the proposed wall would simply have siding installed over the framing.
Thanks
