Closed Cell Spray Foam Insulation in Tulsa OK — Moisture Barrier + Insulation in One

If you have a crawl space with moisture problems, a metal building that sweats in summer, or exterior walls that need both insulation and a vapor barrier — closed cell spray foam insulation is what you need. It's denser and stronger than open cell, with the highest R-value per inch of any insulation on the market. For Tulsa homes dealing with humidity, flooding risk, or structural concerns, closed cell is the premium solution.

When You Need Closed Cell Spray Foam Insulation

Closed cell is the right choice when moisture is a concern. Crawl spaces, basements, rim joists, and exterior walls below grade all benefit from closed cell's built-in vapor barrier. If you've had water intrusion, mold, or musty smells in these areas, closed cell stops the moisture from getting in. It's also the go-to for metal buildings, pole barns, and commercial spaces where condensation is a constant problem. In Oklahoma's tornado-prone climate, the added structural rigidity of closed cell foam — it increases wall racking strength by up to 300% — is a real bonus.

Our Closed Cell Spray Foam Process

We start with a free on-site inspection to assess moisture conditions and measure the area. On install day, our SPFA-certified team applies the closed cell foam in thin lifts, building up to the required thickness. The foam cures rigid and dense — you can walk on it in a crawl space or push against it in a wall cavity and it won't compress. Most residential closed cell jobs are completed in one day. We protect your home during installation, clean up completely, and walk you through the finished work.

Closed Cell Spray Foam Cost in Tulsa

Closed cell costs more per board foot than open cell spray foam insulation, but you need less of it to hit the same R-value. The total cost depends on square footage, thickness, and site accessibility. For many applications — especially crawl spaces and moisture-prone areas — closed cell is actually the more cost-effective choice long term because it eliminates the need for a separate vapor barrier. We provide an exact written quote before any work starts. No hidden fees.
