As a recycled paper product cellulose is prone to absorb moisture that can cause wood rot and mould.
Cellulose too heavy attic.
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.
I can barely crawl there.
Blow cellulose in the green areas since it is hard to get there.
List my plan is to reach the recommended r49 grade by.
When cellulose soaks up moisture in enclosed areas it can take a long time to dry out.
Much less the cellulose in the walls since it is sealed behind the walls.
I would recommend adding an r 40 which would bring you to the maxiumum insulation and the point of diminishing returns on your investment.
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.
You said adding ventilation has eliminated your moisture problem.
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.
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.
The top part of the attic is very low about 2 only at the highest spot.
The mounds of loose material fill.
First attic spaces can be overfilled to account for settling.
Unless you are visiting your attic often there is no way for the cellulose to get into the living area of the house.
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.
Dry blown cellulose will characteristically settle and sag in place reducing its r value.
No one has ever reported a case of a ceiling sagging let alone.
I ve heard rumors that cellulose can be pretty heavy and could be dangerous if you put too much up there.
There is a continuous ridge vent and gable vents on both sides plus a small attic fan.
There are literally millions of homes with cellulose insulation in the attic with installed r values up to r 60 and higher.
The weight ratio per square foot of 8 1 2 of cellulose is usually 97 pounds per square foot.
Settling in attics is less problematic for two reasons.
This should not cause a problem.
