Siding and insulation 100+ year old house - any advice?
I have an old house that has double wood walls. Wood on the inside, under the sheetrock, then 2x4 support studs and horizontal fire breaks, then wood siding on the outside. I need to replace the siding, and am having difficulty finding wood siding. I was considering going with plywood covered by Hardieboard siding. I have heard that if you try to insulate walls that are designed for dead air insulation you may end up with serious moisture issues inside the walls, but all of the hardware store employees keep telling me that I have to insulate them. So is it better to leave the house as it was built to be? Or take the moisture risk of insulating. The house is on the Edwards Plateau in central Texas.
