Which CSI Specification Division addresses thermal roof insulation?

The correct choice pertains to Division 7 of the CSI (Construction Specifications Institute) MasterFormat, which covers thermal and moisture protection. This division specifically includes specifications related to roofing, waterproofing, damp proofing, and thermal insulation, all essential aspects for ensuring adequate thermal performance in building envelopes.

Thermal roof insulation is a critical component in maintaining energy efficiency and regulating interior temperatures in buildings. It plays a significant role in reducing heat transfer, which is vital for energy conservation and compliance with building codes regarding energy efficiency. The specifications under Division 7 detail various types of insulation materials and their applications, along with installation requirements and performance criteria.

The other divisions listed do not focus on thermal insulation specific to roofing. Division 5 deals with metals, Division 6 encompasses wood and plastics, and Division 8 is about openings, none of which directly address roof insulation. Therefore, understanding that thermal roof insulation falls under the broader category of thermal and moisture protection in Division 7 clarifies why this is the correct answer.
