In this reading, Ching begins with chapter 7 to talk about Moisture and thermal protection. In other words, ways to keeping moisture out and letting enough heat in the building. He suggests flashing along roof edges, wall exterior, doors and windows. In addition, he provides the 3 basic means of controlling heat gain or loss which are: The selection of building materials, correct insulation and enclosure and orientation on the site. Then, he moves on to talk about thermal insulation, and explains that it’s the primary purpose to control the flow of the heat through exterior assemblies to prevent heat loss in cold season and vice versa. Later in chapter 7, he goes in depth to explain that wall flashing collects moisture in the wall, or in other words, kicks water out of the wall. Then, he introduces insulating materials such as Batt ( blanket/roll), Rigid Foam, Foamed-in-Place, Loose fill, and Reflective insulation. Lastly, he defines vapor retarders as a material of low performance installed in construction to prevent moisture from entering and reaching certain places, and the major types of ventilations are: Whole house, Energy recovery, Roof & attic, and Crawl Space ventilation.
