Attic Insulation & Weatherization

Weatherization is the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation, and wind. Weatherization also includes modifying a building to reduce energy consumption and optimize energy efficiency. Weatherization is an element of Home Performance.

What happens inside a house? Hot air rises and creates a positive pressure at the top of the house, as noted by the illustration below. The pressure forces the hot air to leak out of recessed lights, bathroom fans, attic hatches, and other crevices. This process creates a negative pressure at the bottom of the house, so air is being drawn into the bottom of the house at the same rate as it is being lost at the top.

The energy audit results in data that indicates what strategies should be used to improve the comfort and efficiency of a home. Weatherization is one of those strategic elements.

For most homes, the work process follows:

  1. Seal the top of the house including lights, bathroom fans and all leaks going into attics.
  2. Add attic insulation to the recommended level.
  3. Install insulation and a radiant barrier on vertical walls of the attic.
  4. Seal the house – including doors, windows, crawlspaces, basements etc.
  5. Add insulation to the air/thermal boundary of the crawlspace
