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

Abstract
Attics on roofs can be designed and constructed to be either vented or unvented in any hygro-thermal zone. The choice of venting or not venting is a design construction choice not a requirement determined by the physics or by the building code.
