How much does spray foam insulation cost?

Spray foam insulation in Dallas-Fort Worth costs $1.50–$4.50 per board foot depending on open-cell vs closed-cell. A typical sealed-attic project runs $4,000–$12,000.

What's the difference between open-cell and closed-cell spray foam?

Open-cell is softer, less expensive, and vapor-permeable — best for interior applications. Closed-cell is denser, higher R-value, and vapor-impermeable — best for exterior walls, rim joists, and moisture-prone areas.

Is spray foam safe once cured?

Yes. Properly cured spray foam is inert and safe. During and immediately after application, ventilation is required; the work area is safe to reoccupy per manufacturer specifications.

How long does spray foam insulation last?

Spray foam does not sag, settle, or lose R-value over the life of the building — typically 80+ years.

Can spray foam be added to an existing home?

Yes, in accessible areas like attics, crawlspaces, and rim joists. Adding spray foam to closed exterior walls requires demolition or open-cell drill-and-fill.

Spray Foam Insulation in Dallas-Fort Worth

Open-cell and closed-cell spray foam for attics, walls, and rim joists — the highest R-value per inch.

Overview

Spray polyurethane foam (SPF) is the premium insulation option. It expands to fill every cavity, creates an air seal in the same step, and delivers R-3.5 to R-6.5 per inch (roughly double fiberglass). It's the right choice for tight spaces, rim joists, and 'sealed attic' assemblies popular in North Texas.

Open-cell foam is softer, less expensive, and vapor-permeable — best for interior walls and attic underdecks. Closed-cell foam is denser, higher R-value, and vapor-impermeable — best for exterior walls, rim joists, and any surface that might see moisture.
