Blowing cellulose in 2x4 wall with existing R8
There is a 1 3/4" gap between the drywall and fibreglass insulation in my
walls. Would it be possible to blow in cellulose to fill that space. There
doesnt seem to be any vapour barrier, at least I can not feel it with my
probe. I'm using a 1.5" 90 degree elbow attached to the blower hose.
Thanks
