I was wondering if any of you had opinions on the best wall insulation. I am building a new home in Houston, Texas, and the standard wall insluation is R-13 unfaced batts in 2x4 walls and R-19 on exterior 2x6 walls. The standard insulation in the attic (two story home) is R-30.
I am going to upgrade to R-38 blown in for the attic, and have been given a quote for Ownes Pro-Pink blown in for the exterior walls. Have any of you had experience with this stuff and what are your thougts versus cost as it is 2-3 times the cost.
Also, they are using cellulose spray for sound control on some of the ceilings and R-11 owens-corning sound batts around some interior walls. Why not just use spray on substances or other?
Essentially, I am in need of help for the best reccomendation on insulation for the house. We went with three Trane 14 SEER, 80% variable furnace systems with Lennox media filters in the house and want to maintain as much energy efficency as is worth the cost. Thank you for your help.
