Icynene in an old house?
DW and I are in the process of renovating a 2-family house in Cambridge MA (hence an area with both plunging cold temps and wind, and with plenty of heat and humidity also). The house is a 100-year-old house with a lathe-and-plaster wall construction and no insulation in the walls.
We are talking with an insulation guy about having Icynene reformulated in a slow-grow mix blown into the walls of the house. Someone raised the concern that Icynene blown into the walls can cause problems with buckling of the lathe-and-plaster or oozing out of holes like electrical receptacles.
Does anyone have experience blowing Icynene into an old house without taking the walls down, and would they care to share their experiences?
