Cellulose Too Heavy Attic

The top part of the attic is very low about 2 only at the highest spot.

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. Blow cellulose in the green areas since it is hard to get there. There is a continuous ridge vent and gable vents on both sides plus a small attic fan. This should not cause a problem.

I can barely crawl there. No one has ever reported a case of a ceiling sagging let alone. Much less the cellulose in the walls since it is sealed behind the walls. I suspect most of your dust comes from other sources.

Settling in attics is less problematic for two reasons. Or roof structures cellulose may be too heavy. 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.

As a recycled paper product cellulose is prone to absorb moisture that can cause wood rot and mould. Dry blown cellulose will characteristically settle and sag in place reducing its r value. 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. Second when cellulose insulation in attics settles no empty spaces are formed.

The mounds of loose material fill. First attic spaces can be overfilled to account for settling. When cellulose soaks up moisture in enclosed areas it can take a long time to dry out. 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.

The weight ratio per square foot of 8 1 2 of cellulose is usually 97 pounds per square foot. 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. 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. I would recommend adding an r 40 which would bring you to the maxiumum insulation and the point of diminishing returns on your investment.
