The weight ratio per square foot of 8 1 2 of cellulose is usually 97 pounds per square foot.
Cellulose too heavy attic.
The mounds of loose material fill.
I suspect most of your dust comes from other sources.
I ve heard rumors that cellulose can be pretty heavy and could be dangerous if you put too much up there.
When cellulose soaks up moisture in enclosed areas it can take a long time to dry out.
There is a continuous ridge vent and gable vents on both sides plus a small attic fan.
Cellulose is known to create a massive cloud of dust when it is installed meaning breathing apparatus is required if you are considering a large installation.
This should not cause a problem.
The top part of the attic is very low about 2 only at the highest spot.
Blow cellulose in the green areas since it is hard to get there.
Dry blown cellulose will characteristically settle and sag in place reducing its r value.
You said adding ventilation has eliminated your moisture problem.
As a recycled paper product cellulose is prone to absorb moisture that can cause wood rot and mould.
Or roof structures cellulose may be too heavy.
If your attic has a lot of nooks and crannies your best bet may be to use loose fill insulation made of fiberglass or cellulose.
No one has ever reported a case of a ceiling sagging let alone.
With at least 3 of cellulose overblow 6 is better the sucky aspects of low density batts falls off dramatically since convection current between the attic air and entrained air in the fiberglass layers can no longer occur due the higher air retardency of the cellulose.
List my plan is to reach the recommended r49 grade by.
I would recommend adding an r 40 which would bring you to the maxiumum insulation and the point of diminishing returns on your investment.
Second when cellulose insulation in attics settles no empty spaces are formed.
I can barely crawl there.
Unlike fiberglass insulation installed in roll out batts on the attic floor cellulose is blown into the attic under air pressure through large diameter hoses.
I ve heard rumors that cellulose can be pretty heavy and could be dangerous if you put too much up there i m going to blown in cellulose in my attic.
There are literally millions of homes with cellulose insulation in the attic with installed r values up to r 60 and higher.
Unless you are visiting your attic often there is no way for the cellulose to get into the living area of the house.
