Closed Cell Spray Foam Insulation in Lubbock, TX

Closed-cell foam is the high-performance choice for crawlspaces, exterior walls, pole barns, and any application where you need both insulation AND a moisture barrier. Summer cooling bills and dust infiltration? Closed-cell solves it.

Why Closed-Cell in Lubbock?

Closed-cell spray foam is denser than open-cell — about 4x heavier per cubic foot. That density gives it three properties open-cell can't match:

• Moisture barrier — closed-cell is approved as a Class II vapor retarder
• Higher R-value per inch — R-7 per inch vs R-3.5 for open-cell
• Structural reinforcement — closed-cell adds racking strength to walls

For Lubbock homes, closed-cell is the right choice for:

• Crawlspace encapsulation — stops summer cooling bills and dust infiltration cold
• Exterior walls in new construction — racks the building, blocks vapor
• Below-grade walls — full basement perimeter foam
• Pole barns and metal buildings — extreme temperature swings need higher R-value
• Roof decks — for unvented attic conditioning

Pricing & Timeline

Closed-cell foam runs $1.50–$3.00 per board foot installed in TX (one board foot = 1 sq ft × 1 inch thick). A typical 1,500 sq ft crawlspace encapsulation runs $5,000–$8,000. Pole barn jobs vary widely based on size and ceiling height — most run $3,500–$12,000.
