Closed-cell vs. open-cell spray foam — what each product does and where each belongs
Spray foam insulation is applied as a liquid that expands on contact — filling cavities, bonding to surfaces, and curing into a rigid or semi-rigid foam that provides both thermal insulation and air sealing simultaneously. No other insulation product delivers both in a single application. That combination — thermal resistance plus a real air seal — is why spray foam consistently outperforms fiberglass batts and blown-in insulation in real-world energy performance, particularly in Texas’s extreme climate.
There are two types of spray foam, and understanding the difference is essential to getting the right product in the right location.
Closed-cell spray foam cures rigid, delivers R-6 to R-7 per inch, and acts as a Class II vapor barrier. It bonds directly to steel, wood, and concrete — making it the right product for metal buildings, shops, barndominiums, attic rooflines, crawl spaces, and any application where moisture control and high R-value per inch are priorities.
Open-cell spray foam cures soft, delivers approximately R-3.5 per inch, and is vapor-permeable. At a significantly lower cost per board foot, it is the right product for interior wall cavities in residential construction, sound control applications, and attic rooflines where vapor management and budget are the primary considerations.
Every spray foam job we do starts with the right product choice for each specific assembly — not a default to one product for everything. See our individual service pages for how each product is applied in specific applications across North Houston and East Texas.

What open-cell spray foam does that fiberglass and batts can't
Complete cavity fill. Real air sealing. Superior sound control. All at a price point that makes sense for interior residential applications across North Houston and East Texas.
Complete Cavity Fill
Unlike fiberglass batts that leave gaps around wires, pipes, and irregular framing, open-cell foam expands to fill every void in a wall or ceiling cavity. No cold spots. No air pathways. No voids.
Real Air Sealing
Insulation and air sealing are two separate things — fiberglass insulates but doesn't seal. Open-cell spray foam does both in a single pass, which is why it consistently outperforms fiberglass on energy efficiency even with a lower R-value per inch.
Sound Dampening
Open-cell's soft, spongy cell structure absorbs sound waves rather than reflecting them. It's widely used in interior walls between rooms, home offices, media rooms, and anywhere noise transmission between spaces matters.
Half the Cost of Closed-Cell
Open-cell uses less raw material per cubic foot and expands more dramatically on application. For interior jobs where closed-cell's structural and moisture-barrier properties aren't needed, it's a significantly more cost-effective solution.
Works Well in Conditioned Attics
Spraying the roofline instead of the attic floor converts the attic into conditioned space — protecting HVAC equipment from extreme Texas heat, keeping ductwork inside the thermal envelope, and cutting cooling loads year-round.
Lasts Without Settling
Open-cell foam doesn't compress, sag, or lose R-value over time the way fiberglass batts do. Properly installed, it performs the same in year 25 as it did in year one.

Spray foam insulation FAQs — North Houston & East Texas
What is spray foam insulation and how does it work?
Spray foam insulation is applied as a two-component liquid that expands on contact with the surface — filling cavities, bonding to the substrate, and curing into a foam that provides both thermal insulation and air sealing simultaneously. The expansion happens immediately on application and the foam reaches full cure within hours. The result is a continuous, seamless insulation layer that conforms to every surface — unlike batts or blown-in, which leave gaps at every obstacle, seam, and framing member.
How much does spray foam insulation cost in Texas?
Open-cell spray foam for residential wall cavities typically runs $0.44–$0.65 per board foot. Closed-cell for metal buildings, attic rooflines, crawl spaces, and high-performance residential applications typically runs $1.50–$3.00 per board foot. Specific pricing for each application type — shops, garages, attics, crawl spaces — is listed on the individual service pages. We visit your building and give you a firm written estimate before any work begins.
Is spray foam worth it in Texas?
For most applications in Texas, yes. The primary reason is air sealing — fiberglass and blown-in insulate but do not seal air pathways, and air leakage is responsible for 25–40% of heating and cooling loss in typical homes. Spray foam addresses both thermal resistance and air sealing simultaneously, which is why spray-foam-insulated buildings in Texas consistently outperform fiberglass-insulated ones on energy costs. For metal buildings and shops, spray foam is the only product that bonds to steel and stops condensation — there is no real alternative for those applications. For residential wall cavities on a tight budget, fiberglass with careful air sealing is sometimes the practical choice. We give you an honest assessment for your specific building.
What is the difference between open-cell and closed-cell spray foam?
Closed-cell delivers R-6 to R-7 per inch, acts as a Class II vapor barrier, bonds to steel, and cures rigid — providing structural reinforcement to the building assembly. It is the right product for metal buildings, crawl spaces, attic rooflines where moisture control is a priority, and any application demanding maximum R-value per inch. Open-cell delivers approximately R-3.5 per inch, is vapor-permeable, and cures soft — making it the cost-effective choice for residential wall cavities, interior applications, and attic rooflines where a full vapor barrier is not required. We recommend the right product for each assembly based on your building type and climate zone.
How long does spray foam insulation last?
Properly installed spray foam insulation is a permanent installation — it does not settle, sag, or lose R-value over time. Closed-cell foam is structurally rigid and performs identically in year 30 as it did on installation day. Open-cell foam maintains its structure and air sealing performance without maintenance or replacement. Spray foam outlasts every other commonly installed insulation product in both thermal performance and air sealing effectiveness.
Do I need to leave during spray foam installation?
Yes — occupants, including pets, should vacate the building during spray foam installation and for the re-entry period afterward. For residential applications, the standard re-entry period is 24 hours after spraying is complete. Commercial and metal building applications may have different re-entry requirements depending on the specific product and ventilation conditions. We advise you on the specific re-entry time for your project before we begin.
Does spray foam require any maintenance?
No — once cured, spray foam requires no maintenance. It does not need to be topped off, re-installed, or inspected on a regular basis. Exposed spray foam in occupied spaces requires a thermal barrier per building code — typically drywall or an intumescent coating — but the foam itself is a maintenance-free installation for the life of the building.
