Practical implications of the elimination of natural attic ventilation in mixed climates

To obtain a copy of a specific publication, users should contact the publication's publisher directly.

Abstract
Many attics are retrofitted with additional ventilation, primarily ridge ventilation, when the roof covering is replaced. The driving forces forthis action are usually the presence of mold, wet insulation, wet or weakened wood, or the premature aging of the roof covering. A protocol for determining the effects of the added ventilation is developed. Several occupied whole buildings are surveyed to determine the reasons the ventilation was added and to establish a base for determining the outcome of the additional ventilation.
