I need to insulate my exterior facing walls in my homeThey are too thin to add foam or blow in insulation toInstead of removing the plaster board walls that we have now and adding insulation then replacing the old walls with drywall.I thought I could add that dense foam board and cover that with drywallWould that work to insulate well?Presently you can feel the cold air blowing in from the outside because we just don't have any insulation at all in our wallI'm hopefull that by adding this foam board and drywall layer this will cut back on wasted money/energy trying to keep our home warm/cool
getting it filled with blown insulation would be the best as far as effiency goes but it also the most expensive and depending on how old your plaster walls are they will probobly crack and maybe even blow holes in itblue board would be the cheepest and the most simple way to insulate without renovationdont forget you will need atleast 2 1/4 inch screws to fasten your drywall to your wall studs behind the blueboard and plaster wallsI dont think it will hold up well if u just fasten it to the blueboard.
My dream is to stuck with elevator with ONE super smoking college girl.
