Precision Thermal & Moisture Protection Estimating
Forensic material quantity takeoffs for commercial roofing, below-grade waterproofing, air/vapor barriers, and thermal insulation. Project-specific delivery in editable Excel sheets and color-coded PDF plan markups.
Building Envelope: quantities, checks and quote requirements
An envelope package coordinates roof, wall insulation, air barriers, waterproofing and joints across their assembly interfaces. Individual product takeoffs remain separate.
Measurement and reporting basis
- Roof and wall assembly area (SF)
- Joint, flashing and transition lengths (LF)
- Penetrations and termination accessories (EA)
Documents to include
- Wall and roof sections with assembly tags
- Air-barrier and waterproofing transition details
- Envelope specifications and trade responsibility matrix
Also identify the current revision, addenda, project ZIP code, requested trades and bid deadline.
A scope check before pricing
Assign roof-to-wall and below-grade transitions to one package, then reconcile totals with roofing, insulation and waterproofing takeoffs. Do not count the same membrane under two trade contracts.
Scope limits: Envelope design, energy modeling and weather-tightness certification are excluded.
Worked estimating example
Assign roof-to-wall transitions once
A 200 LF roof-to-wall interface may appear in roofing and air-barrier documents. Including it in both subcontract totals can duplicate the transition scope.
- What the estimate should record
- Reconcile the detail reference and responsible package, then keep membrane SF, transition LF and penetration EA separate across the envelope summary.
- Resolve before pricing
- Who owns the transition, and which adjacent trade has expressly excluded it?
The written quote defines the deliverables and revision coverage. Measured quantities and drawing markups can be supplied for the agreed scope; a priced estimate adds the identified material, labor and equipment cost basis. Missing information is recorded as a clarification or allowance.
US project coverage for building envelope
Request remote building envelope support for projects across all 50 US states. Include the project ZIP code and the location-sensitive inputs below. Quantities-only takeoffs and priced estimates have separate agreed deliverables.
- Use the issued regional envelope specifications and assembly transitions rather than assuming a standard roof or wall system.
- Identify supplier delivery costs and the responsible trade for roof-to-wall, below-grade and opening interfaces before combining the envelope package.
The proposal records the pricing date, cost sources and unconfirmed allowances. Explore US service area information or send your project details for a scope quote.
Send the documents above for a written quote confirming the scope, fee and delivery date after document review. Indicate whether you need quantities only, a priced estimate or a review of an existing bid.
Request a building envelope scope quoteCSI 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?
Delivery depends on the drawing set, requested trade scope, pricing requirements and bid deadline. The delivery date, scope and revision coverage are confirmed in the written quote after document review.
