We mainly think of walls in terms of insulation and R-value, something that is not or prime importance in our North Texas climate. But walls are important in other ways, even in North Central Texas.

Walls function to control and support, distribute utilities and other services, and beautify (or "uglify") our homes. 

Before we can understand what the walls are not doing correctly in our homes, we need to understand what they  include and their proper functions.

A building enclosure includes the roof, walls, openings, foundation, and below ground materials that separate the building from its surrounding environment. It adds a thermal barrier, a vapor barrier, drainage planes, and an air barrier.
