Re: Insulation Question

I'd be more concerned about the vent. Moisture in the attic is going to cause many problems beside lower the insulation R factor.

If you have R-38 blown in and batts on top of it, it is probably already R-49. I don't know the weight of cellulose insulation. It's been 20 years since I looked at it but if it's heavy it could compress your other insulation and decrease the effectiveness of it.
