I had need to be up in my attic crawl space recently, and I noticed that in the area immediately above the plumbing wall that is common to my kitchen and to the bathroom, there was no insulation at all.
Is there any logical reason for the missing insultation other than that the space is narrower than the normal distance between joists and the batts of insulation would not fit, unless cut ?
I suppose that I should simply add what I believe is missing, but thought that I would ask here first. I think that at least in the area around the stack/vent insulation should be added, since this leads directly into an unheated basement, etc.
Thanks.
