Green Building Glossary

 

 

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. 

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

The control function of the walls is quite important. They actually control:

  • Rain and snow penetration
  • Pollution, dust, other contaminants or environmental hazards  
  • Heat flow
  • Airflow, including wind
  • Water vapor 
  • Groundwater
  • Light 
  • Solar radiation
  • Fire
  • Noise
  • Entrance of animals, bugs, vermin
  • Entrance of unwanted humans
  • Odors  

Unfortunately, when controls fail, your home often begins to develop problems. 

However, we mainly think of walls in terms of insulation and R-value, something that is not or prime importance in our North Texas climate.
