I am going to reside my house with Hardiplank. House was built 1986 with rigid foam sheathing, foil faced on both sides, one side says Thermal in blue letters. Cedar lap siding will be coming off. There is a vapor barrier over the insulation. Should I replace this vapor barrier since it is now full of holes? should I put 15# felt on instead, then the Hardiplank. Last, how can I do one wall at a time, but over lap the corners?
