Will I need house wrap and /or rainscreen?
Existing exterior is Textured 111 plywood (with vertical groove 8″ o.c.) over stud with 1X4 interior , exterior corner, window, door and soffit (header) trim.
Would like to reface with Western Red Cedar 1X8 T&G vertical siding (WWPA Profile 1600). Would like to install over new horizontal wood furring (that would bridge the existing T-111 groove which would remain open and unobstructed) and have some of the existing trim act as furring. The bottom and top new siding will be slightly routed out in the back (simulating the existing T-111 groove) to allow for drainage and breathing (circulation). All this without the use of house wrap and/ or rain screen. (The T-111 is now breathing). Yes, cedar will have all surfaces and edges factory sealed. I would like to have the existing T-111 grooves act as my rain screen.
Will this work without using house wrap and/or rain screen.
Comments and/or other suggestions please.
