Insulation Estimating Services & Building Envelope Takeoffs
Commercial and residential building envelope takeoff services across the USA. We calculate insulation R-values, air/vapor barriers, single-ply roofing, firestopping, and joint sealants with quantities organized by scope.
Complete CSI Division 07 Building Envelope Takeoffs
Thermal and moisture protection estimating forms the weather barrier defense of any structure. An oversight in continuous insulation thickness, air barrier lap waste, or perimeter joint caulking can result in costly code compliance failures and moisture damage.
At F&K Estimatings, our envelope cost engineers audit architectural wall sections, roof plans, and exterior details. We itemize every square foot of thermal batt, rigid board, spray foam, air/vapor barrier membrane, and linear foot of joint sealant.
We provide complete line-item Excel schedules and marked-up plan sets within 24 to 48 hours to help you submit competitive, winning proposals.
Scope, price, and delivery are confirmed after reviewing the project documents and requested deliverables.

Frequently Asked Questions
Do you calculate exact R-value insulation thicknesses and assembly types?
Yes, we provide highly accurate square footage takeoffs for fiberglass batts, rockwool acoustic/fire batts, blown-in cellulose, continuous polyiso/XPS board, and open/closed-cell spray polyurethane foam (SPF), matching specified R-values (R-13 to R-49+) and IECC/ASHRAE energy codes.
Can you estimate complex roofing assemblies, cover boards, and tapered insulation?
Absolutely. We quantify all single-ply TPO, PVC, and EPDM roofing systems, calculating board-foot counts for tapered insulation fill, cricket layouts to drains, DensDeck cover boards, and mechanically attached vs. fully adhered adhesives.
How do you handle continuous air & vapor barriers and weather resistive barriers (WRB)?
Our building envelope estimators calculate exact net and gross square footage for self-adhered vapor-permeable and non-permeable air barriers (Blueskin, Tyvek, Henry), including window flashing tapes, sealants, and lap waste factors.
Do your takeoffs include perimeter joint sealants, expansion joints, and through-wall flashings?
Yes. We quantify silicone and urethane joint sealants, backer rods, continuous elastomeric expansion joint covers, and copper/stainless steel through-wall flashings at masonry shelf angles and parapet copings.
What is your typical turnaround for a CSI Division 07 estimate?
Standard commercial thermal and moisture protection packages deliver within 24 to 48 hours. Large-scale high-rise building envelopes or industrial manufacturing plants deliver in 3 to 4 business days.
