Cellulose Too Heavy Attic

Blow cellulose in the green areas since it is hard to get there.

Cellulose too heavy attic.

This should not cause a problem. Settling in attics is less problematic for two reasons. Dry blown cellulose will characteristically settle and sag in place reducing its r value. 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 can barely crawl there. I would recommend adding an r 40 which would bring you to the maxiumum insulation and the point of diminishing returns on your investment. 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. 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.

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. Or roof structures cellulose may be too heavy. I suspect most of your dust comes from other sources.

The top part of the attic is very low about 2 only at the highest spot. When cellulose soaks up moisture in enclosed areas it can take a long time to dry out. There are literally millions of homes with cellulose insulation in the attic with installed r values up to r 60 and higher. List my plan is to reach the recommended r49 grade by.

Much less the cellulose in the walls since it is sealed behind the walls. First attic spaces can be overfilled to account for settling. There is a continuous ridge vent and gable vents on both sides plus a small attic fan. 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.

Second when cellulose insulation in attics settles no empty spaces are formed. The mounds of loose material fill. I ve heard rumors that cellulose can be pretty heavy and could be dangerous if you put too much up 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.
