Wool Or old Cellulose?

What type of insulation? I’m thinking old cellulose ? Would you comment on updating this as it looks pretty settled at this point also.


1st picture looks like topsoil, Lol
2nd pic is cellulose and is covering the ceiling joist.
What climate zone are you located in will make a difference on your R-factor that is needed.

My take…
Balsam wool in the top photo.
Cellulose in the section photo.

Why replace it when it can be “raked and fluffed”?
It never wears out, just settles and compresses.

Yes, I’d comment, “consider increasing the insulation to a uniform value of R-50 across the entire attic, including the eaves. If this is not possible, insulate to R-60 wherever possible.” This is the current recommendation for my climate zone #7. I don’t worry about settling, it’s depth and R-value that are important. In an open attic, insulation cost against energy savings has a short payback.

I don’t make this observation into a major issue. It’s not a deal breaker. However, it’s something a new owner should be aware of relative to heating costs.

Afternoon, Michael.
We do not know if the attic is sealed.

Eaves are part of most attic ventilation systems. Insulation dams prevent eaves from becoming blocked with insulation.

Absolutely! Following the focus of @tpresley’s post, my comment was insulation focused and does not cover all aspects of energy use reduction in the attic. Yes, the need for rafter chutes is paramount as is the need for adequate and balanced attic ventilation. In addition, air sealing of ceiling penetrations has to be performed prior to adding any insulation in the attic.
