I have a one-story house with an attached garage. The house has soffit vents and attic fans for ventalation. The attic over the house portion seems adequately insulated, but there is no insulation over the garage portion of the attic.
I'm in TX and the garage is on the west side of the house. Is there a reason for the garage not being insulated, other than saving the builder $$$, and would it be beneficial to insulate the attic over the garage?
