What is better to use, foam in the exterior walls or go with Blow-In-Blanket (BIB) insulation?
We are building a home near Dallas. We are using 30# felt as the housewrap w/Brick construction and Demilec Sealection 500 open cell foam in the attic. We are trying to decide whether to use the same foam in the exterior walls or go with the Blow-in-blanket (BIB) insulation. Do you have any recommendations? Also if you any other thoughts for the attic as it relates to the use of spray foam (or if any other products are better and safer), please let us know. Thanks.
