We have a cabin in the Bershires of Massachusetts ceilings and floor have been insulated, dense pack celluose in ceilings 4 in Amivic graphite EPS under floors.
Walls have no insulation, siding is T-1-11 from the sixties would like to put 1 inch EPS under vinyl siding. the building is pretty well built. no sagging parts no gaps no structural issues, drywall in good shape. would the 1 inch EPS under vinyl siding be a problem with condensation on inside of walls would vapor barrie paint help over the old paint. What type of house wrap and where do you put it under EPS or over EPS.
