Spray Foam Insulation Cost by Type Guide

The job priced by foam type: open-cell rows and closed-cell rows apart, frame by frame.

Orange County, CA · Updated 2026 · Costs shown as ranges — your quote will vary by installer and scope

Reading this guide: every figure below is a range from published 2026 pricing data — not a quote. Two frames are named apart and never blended: Frame A (the Angi frame) and Frame B (the HomeGuide frame). The frames count the same job differently, and that difference is named on every page. Always get 3 written quotes.

The type readings, priced apart by frame

Foam typeFrame A readingFrame B reading
Open-cell spray foam$0.60-$1.60 materials row$1.50-$3.50 installed row
Closed-cell spray foam$1.30-$3.10 materials row$3.00-$5.00 installed row

Each reading is one frame counting of one foam type in one job, never blended across types or frames. The open-cell lane and the closed-cell lane stand apart on every table here, and a per-type row is never folded into a whole-insulation ticket on this page.

The board-foot and per-job rows, priced apart inside each frame

RowFrame A readingFrame B reading
Polyurethane, per board foot$0.44-$1.50no board-foot row
Pro-completed job, per 1,000 square feet$1,500-$6,200counted by area rows
Installed band, per square foot by area$1-$5in per-type installed rows

The board-foot row counts material by thickness and area together inside Frame A alone. Frame B prints no board-foot row, and that absence is printed rather than filled from the other frame.

The totals behind the rows, priced apart

Total line, as publishedFrame2026 reading
Installed, 3,000 square feetFrame A$3,000-$15,000
Whole house row, by areaFrame B$8,000-$20,000
Small-project minimum rowFrame B$1,000-$2,000+

The totals count the whole job behind the type rows: a type row prices the type lane, a total line prices the job, and no page adds type rows into one blended total. The frames count the same closed-cell job differently -- an Angi materials-only per-foot row at $1.30-$3.10 against a HomeGuide installed per-foot row at $3.00-$5.00. That difference is named as a frame difference on every page here, never averaged.

The neighbours named apart

Scope readings price apart on the companion guide. Named apart, never a row here: the attic insulation ticket, the crawl-space insulation ticket, blown-in and batt materials, insulation removal, radiant barriers, and whole-house insulation packages, each in its own lane.

Frequently asked questions

What does spray foam insulation cost by foam type, as reported?

Frame A prints an open-cell materials row at $0.60 to $1.60 and a closed-cell materials row at $1.30 to $3.10 per square foot. Frame B prints open-cell at $1.50 to $3.50 and closed-cell at $3.00 to $5.00 per square foot including installation.

What do the closed-cell rows print at against the open-cell rows, as reported?

The closed-cell lane stands higher in both frames: $1.30 to $3.10 against $0.60 to $1.60 in Frame A materials rows, and $3.00 to $5.00 against $1.50 to $3.50 in Frame B installed rows.

What does the board-foot row print at, as reported?

Frame A prints polyurethane at $0.44 to $1.50 per board foot, and its pro-completed job row at $1,500 to $6,200 per 1,000 square feet. Frame B prints no board-foot row at all, standing on its installed per-foot rows instead.

What does the whole job print at behind the type rows, as reported?

Frame A prints installed work at $1 to $5 per square foot by area, scaling to $3,000 to $15,000 at 3,000 square feet. Frame B prints its whole house by-area row at $8,000 to $20,000, standing apart from every type row.

Is an open-cell job the same purchase as a closed-cell job or an attic insulation ticket?

No. Each row prices one foam type in one job, off a $0.60 to $1.60 open-cell materials row and a $3.00 to $5.00 closed-cell installed row. The attic ticket, the crawl-space ticket, blown-in and batt materials, removal, and radiant barriers sit in their own lanes, named apart.
