Precision Thermal & Moisture Protection Estimating
Forensic material quantity takeoffs for commercial roofing, below-grade waterproofing, air/vapor barriers, and thermal insulation. Fast 24-48 hour delivery in editable Excel sheets and color-coded PDF plan markups.
CSI Division 07 Estimating Overview
Building envelope integrity is the primary defense against water intrusion and energy loss. Our estimators quantify every layer of the thermal and moisture protection envelope—from below-grade foundation membranes and drainage boards to exterior wall continuous air barriers, cavity wall mineral wool insulation, parapet flashings, and multi-ply commercial roof systems.
Complete CSI Division 07 Scope Coverage
Our estimators perform itemized takeoffs across all critical envelope divisions:
Damp-Proofing & Waterproofing
Sheet membranes, bentonite clay panels, crystalline waterproofing, and elastomeric fluid coatings.
Thermal Insulation
Continuous polyiso, extruded polystyrene (XPS), mineral wool, fiberglass batts, and spray polyurethane foam.
Air Barriers & Vapor Retarders
Self-adhered sheet membranes, fluid-applied vapor permeable/impermeable air barriers, and transition flashing.
Membrane Roofing
TPO, EPDM, PVC, built-up asphalt, and modified bitumen roofing systems with tapered insulation schemes.
Sheet Metal Flashing & Trim
Parapet coping, gravel stops, counter-flashing, drip edges, reglets, and scupper boxes.
Firestopping & Smoke Seals
Top-of-wall deflection joint firestopping, curtain wall perimeter fire containment, and rated pipe penetrations.

Frequently Asked Questions
What is included in CSI Division 07 thermal and moisture protection estimating?
Our Division 07 takeoffs encompass below-grade waterproofing (sheet membrane, bentonite, fluid-applied), foundation drainage composite boards, continuous exterior insulation (polyiso, XPS, mineral wool), fluid-applied air and water-resistive barriers (WRB), commercial roofing systems (TPO, EPDM, PVC, modified bitumen, standing seam metal), spray foam insulation, firestopping assemblies, and joint sealants/expansion joints.
How do you calculate membrane waste and flashing details?
We quantify roof squares, vertical parapet wall flashing heights, termination bars, gravel stops, coping caps, pitch pockets, and perimeter lap seams with industry-standard 8% to 15% geometric waste allowances.
Do you estimate continuous building envelope insulation and vapor retarders?
Yes. We detail continuous insulation (ci) square footages, fastener densities, thermal bridging breaks, self-adhering vapor permeable and non-permeable membranes, and transition tapes at window/curtain wall interfaces.
What is the turnaround time for a Division 07 takeoff?
Standard turnaround is 24 to 48 hours for commercial envelope packages. Expedited 24-hour rush delivery is available for urgent bid deadlines.
