Should I install insulation?
My house in LA is about 100 years old and there is no insulation within exterior stucco walls.
I’m debating whether I should install insulation (these pink sheets sold in home depot) since I have a chance to do so.
The stucco looks pretty thin to me. If rain water gets into these pink materials, would it cause fungus growth or maybe bugs build a nest within? A house has its own working built in ventilation and functioning mechanism for 100 years. Maybe I should not disturb it.
