InsulatorOS

Spray Foam Estimating Software, Built by People Who Spray

Most estimating software wasn't designed for insulation — let alone spray foam. You end up doing the foam math on a phone calculator while the homeowner watches. InsulatorOS bakes the foam set calculator into the estimate.

The foam math, automated

Punch in the area, thickness, and chemical type. InsulatorOS calculates board feet, applies your real-world waste factor, and tells you exactly how many sets to put on the truck — open-cell or closed-cell.

From estimate to crew pack list in one click

Every line item on the estimate maps to a real material in your inventory — sets of foam, primer, intumescent paint, fasteners, PPE. When you finalize the estimate, the crew pack list is automatically generated. The truck leaves with the right materials. No more "we left the proto-board at the shop."

Real example: 2,400 sq ft attic, 7" of open-cell foam at $0.95 BF. InsulatorOS quotes the job, generates the pack list (one full set + spare drum of primer + ½ set buffer), and slots it into the schedule — in about 90 seconds.

Why generic estimators don't work for spray foam

Tools like Buildertrend, JobNimbus, and ServiceTitan were built for general contractors and HVAC. They have line-item estimating — but no foam yield math, no open-cell vs closed-cell logic, no density-aware pricing. You end up keeping a spreadsheet on the side. That spreadsheet is where margins die.

Frequently asked questions

How does a foam set calculator work?

It converts the cubic-feet target (square feet × thickness) into sets to buy, accounting for chemical yield, overspray waste, and density. InsulatorOS does this inside every estimate so you never quote the wrong number of sets.

What is the best spray foam estimating software?

Generic estimating tools don't speak insulation. InsulatorOS is purpose-built — it ships with a foam set calculator, open-cell vs closed-cell assemblies, and a crew pack list that auto-builds from the estimate.

Can I estimate open-cell and closed-cell on the same job?

Yes. Each line item carries its own density, R-value per inch, and set yield. Mix open-cell in the attic with closed-cell in the rim joist on the same estimate — totals and packing list both recalculate.

Does it handle batt and blown-in too?

Yes. Assembly library covers fiberglass batts, blown cellulose, blown fiberglass, mineral wool, and rigid board — in addition to spray foam.
