Cellulose Too Heavy Attic

No one has ever reported a case of a ceiling sagging let alone.

Cellulose too heavy attic.

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. There is a continuous ridge vent and gable vents on both sides plus a small attic fan. Or roof structures cellulose may be too heavy. I can barely crawl there.

List my plan is to reach the recommended r49 grade by. I ve heard rumors that cellulose can be pretty heavy and could be dangerous if you put too much up there. Blow cellulose in the green areas since it is hard to get there. 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.

Much less the cellulose in the walls since it is sealed behind the walls. 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. First attic spaces can be overfilled to account for settling. You said adding ventilation has eliminated your moisture problem.

Unless you are visiting your attic often there is no way for the cellulose to get into the living area of the house. This should not cause a problem. The weight ratio per square foot of 8 1 2 of cellulose is usually 97 pounds per square foot. There are literally millions of homes with cellulose insulation in the attic with installed r values up to r 60 and higher.

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. The top part of the attic is very low about 2 only at the highest spot. 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. Settling in attics is less problematic for two reasons.

Second when cellulose insulation in attics settles no empty spaces are formed. I would recommend adding an r 40 which would bring you to the maxiumum insulation and the point of diminishing returns on your investment. The mounds of loose material fill. Dry blown cellulose will characteristically settle and sag in place reducing its r value.
