What moisture level should studs and sheathing be at before starting to insulate exterior walls?

stevensfavorite | Posted in General Questions on

Hi, I live on northern Vancouver island B.C.
Does anyone know what moisture level studs and sheathing should be at before starting to insulate exterior walls?
The moisture content of the walls continually reads between 15% to 17 throughout summer and winter.
Thanks,
Bill

    Bill,
    In general, framing lumber is considered dry when it is at 19% moisture content or less.
