What aspect does Division 7 of the CSI specifications primarily focus on?

Division 7 of the Construction Specifications Institute (CSI) specifications is primarily focused on thermal and moisture protection. This division encompasses materials and systems meant to control thermal performance and manage moisture, which are critical for the integrity and longevity of a building's envelope.

Thermal protection includes insulation, which helps regulate building temperature and energy efficiency. Moisture protection involves elements like waterproofing, dampproofing, and roofing systems that are crucial for preventing water intrusion, which can lead to structural damage, mold, and other issues.

The other divisions listed focus on different aspects of construction; for instance, structural steel pertains mostly to building frameworks and load-bearing systems, plumbing systems address liquid and waste conveyance networks, and electrical systems deal with wiring and power distribution. However, Division 7’s emphasis on protecting a building from thermal and moisture-related issues is foundational to ensuring that a structure maintains its performance and durability over time.
