Division 7 covers materials that control temperature, moisture, and environmental exposure in buildings. Key categories include:

Insulation

Fiberglass, rigid foam, spray foam, and reflective insulation for thermal efficiency.

Waterproofing & Damp Proofing

Membranes, coatings, and drainage systems to prevent water intrusion.

Flashing & Waterproofing

Barriers to protect masonry from moisture intrusion.

Sealants & Caulking

Joint sealants to prevent air and water leaks in building envelopes.

These materials are critical for energy efficiency, moisture control, and fire resistance in construction projects.
