After seeing a reference to Robert Argue’s 1981 Super-Insulated Retrofit book on this site I went out and purchased a lightly used copy online. I am now in need of some advice…following Argue’s plan of wrapping the outside of your home with polyethylene sheeting and building curtain walls filled with horizontal and vertical layers of unfaced fiberglass sounds great..but is there a better combination of materials (roxul in place of fiberglass, ice and water in place of polyethylene?) to achieve the same level of insulation and air tightness? My house is in the NEK of Vermont, balloon framed and little to no insulation in the walls. I would love to use cellulose if possible but it seems risky at best…any thoughts? Maybe a more modern approach? thanks in advance
