Division 07 — Thermal and Moisture Protection: how to specify products in it
Waterproofing, air barriers, insulation, roofing, flashing, firestopping and sealants. Division 07 is the envelope, and the division where a substitution most often goes unnoticed until it leaks.
What Division 07 covers
Everything that keeps water, air, heat and fire where they belong: below-grade and above-grade waterproofing, dampproofing, thermal insulation, weather and air barriers, exterior wall panels and siding, steep and low-slope roofing, sheet metal flashing and trim, roof accessories, firestopping and joint sealants.

What to check before you specify
- 01System compatibility — membranes, primers, sealants and insulation specified together must be approved together by their manufacturers.
- 02Fire performance — insulation and wall-assembly components tested as part of the listed assembly, not in isolation.
- 03Thermal values — R-value or U-factor at the installed thickness and the aged value where the material drifts.
- 04Air and vapor performance — permeance values and the barrier’s continuity details at every transition.
- 05Warranty terms — what the manufacturer’s system warranty requires of adjacent products and installers.
- 06Firestopping listings — each penetration and joint condition matched to a tested system, not a product.
