I am going to replace the old masonite siding on my house with lp smartside and have a few questions.
Foam siding board and then housewrap.
Currently my walls go from the inside out gypsum board poly 2x6 framing with unfaced fiberglass batts black fiber board for sheathing tar or felt paper and then the siding.

That said adding 1 2 to 1 of foam insulation board over sheathing and under siding will do much much.
The foam board portion of the job will cost about 1500.
Doing that extra work involving the different vapor and temperature barriers behind the siding may not be as effective as he wants it to be.
My house currently has cedar shake which i m removing because it is in poor condition.
