When the resistance drops below the threshold, usually around 50 kOhm, the device triggers an alarm.
Do exterior walls need insulation?
If your attic has enough insulation and proper air sealing, and your home still feels drafty and cold in the winter or too warm in the summer, chances are you need to add insulation to the exterior walls.
