Old Walls

Hi, I am renovating a room in a 100 year old house and have removed the inside wall coverings down to the wood plank walls.
I would like to beef up the insulation and am not sure if what I am planning is correct. Currently from the outside in, this is what I have. Vinyl siding, 1 inch rigid insulation, 1 inch planks(outside wall), 4 inch space with wood chips, 1 inch planks (inside wall).
I would like to put 1 inch rigid insulation up on the inside wall. Will that work and should I also put vapour barrier between it and the new drywall.

Yes, you could use 1 inch rigid board insulation that has foil on at least one side that is rated as a vapor barrier. To qualify as a vapor barrier it must be rated as 1 Perm or less. In my work I use .1 Perm rating. Sometimes on the labeling they use W.C. instead of Perm. The W.C. stands for water column.

You should also use a vapor barrier tape and use it to seal where all the pieces of the boards meet.
