how to install cellulose insulation
My 1930 house has no insulation in the walls. I would like to add some cellulose insulation in exterior walls. All the drywall is off and the shiplap walls are exposed; I have a couple of the interior boards off the top of the walls to get access to the cavity. (1) How should I add the insualtion? In two places in the walls there is old wiring (knob and tube, I think). (2) Is it ok to put insulation there? The big-box home supply store said it is treated so it should be ok.
