Which CSI MasterFormat division covers thermal and moisture protection?
Correct Answer
B) Division 07
Division 07 covers thermal and moisture protection, including insulation, roofing, waterproofing, and sealants. Division 06 is wood and plastics, Division 08 is openings, and Division 09 is finishes.
Why This Is the Correct Answer
Division 07 of the CSI MasterFormat is specifically designated for Thermal and Moisture Protection systems. This division encompasses all building envelope components that control heat transfer and moisture infiltration, including insulation materials, roofing systems, waterproofing membranes, air barriers, and sealants. These systems are critical for building performance, energy efficiency, and preventing water damage. Division 07 is universally recognized in the construction industry for these protective building elements.
Why the Other Options Are Wrong
Option A: Division 06
Division 06 covers Wood, Plastics, and Composites, which includes rough carpentry, finish carpentry, architectural woodwork, and plastic fabrications - not thermal and moisture protection systems.
Option C: Division 08
Division 08 covers Openings, which includes doors, windows, skylights, and hardware - these are building openings rather than thermal and moisture protection systems.
Option D: Division 09
Division 09 covers Finishes, which includes flooring, wall finishes, ceiling systems, and painting - these are interior and exterior finish materials, not thermal and moisture protection.
Memory Technique
Use the mnemonic 'Lucky 7 keeps you DRY' - Division 07 handles all moisture protection including waterproofing, roofing, and insulation that keeps buildings dry and thermally efficient.
