Insulating a home with plaster walls
I purchased an older home. There is no insulation in the walls. Exterior walls are 1 inch thick wood with vinyl siding over it. Interior walls are 1 inch thick boards with a plaster lathe strip over studs then plaster lathe and plaster installed as it should be. First floor has 10 foot ceilings, second floor has 8 & 9 foot ceilings. Gutting out interior is to time consuming to insulate. I am considering blown in insulation and using Perlite that I can do myself. Would Perlite be a reasonable insulation choice. Any information would be appreciated.
