Many of the houses in Anna are part brick and part siding. Our master bedroom gets cold because it is the only room with siding outside. I added blown in fiberglass on top of the cellulose a couple of years ago and it really helped the entire house. But before I added it, I went up in the attic, racked the cellulose back from the edges and installed about a two foot insulation batt between each joist,all around the perimeter and racked it back in. This kept it from spilling into the eves when I added more. Another thing is to add "great stuff" foam outside behind the bottom siding board. Reach under it and feel the gap.Air tends to blow in in under the lower wall sill plates. This is just one of the reasons I perferred brick over siding when I brought my house. I have closed some of my register vents about half way in other areas to divert more heat into the cold areas. Hope this helps!
