Home Inspection - Insulation textbook

Inspecting insulation and ventilation systems is particularly challeging because so little of the system can be seen. This text discusses how insulation, air/vapor barriers, and ventilation systems work to keep houses comfortable and structurally sound. Basics of heat transfer and vapor movement are covered first to lay the groundwork for discussion of insulation and ventilation materials, system, and applications. Thorough treatment of venting living spaces is provided, including balanced ventilation systems and heat recovery ventilators (HRVs).
