The attic is only 36" high, at the peak, has a R19 (fiberglass), and in the summer the temperature, up there, gets to be 25 degrees hotter that the outside temperature. I have noticed that the condensation on the ducts is excessive. I am concerned that all of the condensation will eventually get to the dry wall below. Is there any way that I would be able to control this condensation? The ducts already are all wrapped and taped. It would be move the air conditioner blower to another level of the house, but unfortunately, that is not an option. My air conditioner is in the attic.

Sure it's going to compress it but the only important issue is the total depth when they are finished. The compressing will happen almost immediately. It's really not an issue in my book.Yes on the spray foam! Blowing in additional insulation over older insulation is done every day here in the Northeast.

What is your thought on this? Is it better to suck out the older fiberglass and replace it with all cellulose?Also will a few cans of spray foam work best to seal the areas around HVAC vents pipes in the attic? This will help prevent heat/AC loss.By the way I live in Souther Alabama, if that helps.Nate A couple of people have mentioned that they would not blow cellulose over fiberglass in an atic as it compresses the fiberglass and reduces the R-value.

By the way I live in Souther Alabama, if that helps.

A/C....attic vent? It's not uncommon to have this type of situation right after having insulation blown in. It typically goes away after a short period. Do you have any duct work in the attic?

While I can access the attic, the shallow pitched roof only allows limited access to about 2/3rd of the attic area. I highly suspect the cellulose particles are finding their way into the room through the IC rated retro/remodel canned lighting fixtures in ceiling. Any suggestions to mitigate?
