I hear you and many do not understand about ventilation and the dynamics of a home. This one you post is not so bad as the ones I see around here are unbelievably bad.
Did you see any mold like stains or blocked ventilation?
In order to describe I we need to see the entire picture.
To be honest I would not make a huge deal over what I see in this pic. (now this is like 5% of the attic, are there soffit vents blocked? how old is the home? Any visible knob & tube?
I would note unprofessional installation, uneven distribution and recommend someone competent would review for properly installing.
I would note the types and approximate depth R value.
I just posted it for the fun of it. The owner had done this through the entire attic.
He must have purchased the insulation and got a few rolls of it up into the attic only to realize his truss spacing was 24" and he has bought 16" rolls. So the entire attic is insulated with the wrong size and you can tell he just rolled it out from the center and let it be.
I guess he lost steam when he realized he had 40 bags of the wrong size.
The sad thing is if he just went the other direction he could have made it work. Probably would have been cheaper and more beneficial to just blow it in.
