R-Value for finished attic insulation?

R-Value for finished attic insulation?
We have a bungalow style home with a finished attic. I have access to pretty much all of the back of the walls. None of them have any insulation and it was recommended that it be added by our home inspector. I used the r-value calculated and it recommended an r-value of 49. Is this too much for a finished attic. What would you recommend? Thanks.

Living in the midwest with a finished attic, I'd say get as much as you can up there. You may be limited in the ceiling space by the depth of the joist for your R-value.
In the summertime, however, make sure you've got goot roof ventilation to keep the heat buildup down.

You didnt say what the wall studs are here . I think it would be hard to get more than a R13 in them with paper to the room side. The R 49 there would be for a ceiling not the walls. like was said here dont forget to vent all of that attic space winter and summer.

Thanks for the additional info fella's. The very front portion or our attic(which is above the porch) is still unfinish. There's an attic fan in this portion of the attic, and I have access to the whole side of the back walls of the attic from this area. There is also a dummy door on the rear of the attic which provides me w/ access to the back of the walls in that portion. I'm pretty sure the wall studs are 2x4's with 16 inch spacing. I don't think there is any access for me to add insulation to between the ceiling joist in the finished portion of the attic, so in all likelihood I won't be. Pretty much, I'm just looking to add it to the back of the walls.
Should I go w/ R-13 then?

For the walls I would go the R 13. paper side to the room. you could use a wire mesh like to hold it in. You can blow or add more insulation over the ceiling joist there in the attic.
