For SPF insulation contractors

Bid the real yield, not the drum label.

A closed-cell set is rated "up to 5,000 board feet." Real-world yield after cold substrate, humidity, and technique commonly lands at 3,200–3,400. FoamCalc adjusts for job conditions, then logs what actually happened so your own history tunes future bids.

Sets you'll burn, not material consumption units

A free board-foot calculator to start, and a full estimating & job-costing toolkit once you upgrade.

Free Get started

  • Board-foot calculator (area × thickness)
  • Sets required at nominal (rated) yield, open or closed cell
  • 5 saved calculations
  • Ad-supported (banner ads only, never interstitial)

Pro The full toolkit

  • Real-yield estimator — adjusts for temperature, humidity, equipment/technique, and trim waste
  • Yield log — tracks actual vs. estimated yield per job and auto-tunes your personal default over time
  • Multi-zone job builder — attic, walls, rim joist, crawlspace, metal building as separate zones rolled into one total
  • Cost-per-board-foot engine — material + labor + overhead, forward and backward
  • Bid pricing — markup vs. margin shown side by side, so you never confuse the two
  • Thickness ↔ R-value solver — cavity depth presets plus a 2021 IECC climate-zone reference table
  • Flash-and-batt calculator
  • Pass planner — max lift thickness, passes required, cool-down between lifts
  • Set inventory burn-down — sets on the trailer vs. committed to scheduled jobs
  • Production estimator — board feet/day → days on site
  • PDF/CSV/share export — formatted as a bid package
  • Saved job templates — attic conversion, crawlspace encapsulation, pole barn/metal building, rim joist, new-construction walls
What FoamCalc deliberately doesn't do: no code-compliance verdicts anywhere in the app — it gives you inches for a target R-value, never a pass/fail. No vapor-retarder determination, no ignition/thermal barrier lookup, no re-entry/re-occupancy timing guidance, no chemistry/off-ratio troubleshooting, no homeowner energy-savings claims. The R-value reference screen is labeled with its code edition (2021 IECC prescriptive minimums) and always tells you to verify with your local building department.
