Frequently Asked Questions

Spray foam creates a continuous air and moisture barrier that blocks vapor infiltration and prevents mold growth. Unlike fiberglass, it seals joists, voids, and penetrations completely. At Tri Foam Solutions, we use closed-cell foam to stop stack effect airflow and protect floor systems from decay in southeast Louisiana's humidity.

Open-cell foam is softer, has an R-value around 3.5 per inch, and is more cost-effective for interior spaces. Closed-cell foam is denser, offers R-6 to 6.5 per inch, acts as a vapor barrier, and provides structural support. We recommend closed-cell for crawl spaces and exterior applications in humid areas like Belle Chasse.

Most concrete lifting projects are completed in a single day with minimal disruption. The polyurethane foam cures in minutes, allowing surfaces to be used almost immediately. At Tri Foam Solutions, we drill small holes, inject foam to fill voids and lift the slab, then patch and seal for a clean finish.

Yes, spray foam fully adheres to metal surfaces to create an air seal and vapor barrier that eliminates condensation. This prevents rust, mildew, and corrosion caused by humidity. In Louisiana's climate, spray foam stops moisture buildup that fiberglass batts can't control, protecting metal structures year-round.

Concrete lifting with foam costs significantly less than full slab replacement—often less than half when you factor in demolition, removal, and landscaping. Fewer materials, faster completion, and no heavy equipment also reduce labor costs. At Tri Foam Solutions, we deliver durable stabilization without the expense or downtime of traditional methods.

No, spray polyurethane foam can be applied directly over existing materials like concrete, wood, or steel. This eliminates costly tear-offs and landfill disposal. The foam expands to form a seamless, monolithic shell that fills cracks and creates a weather-tight barrier ideal for Gulf Coast climates.

Attic spray foam prevents temperatures from exceeding 120–130 °F, reducing strain on HVAC systems. When applied to the roof deck, it seals the attic into conditioned space and stops heat transfer. At Tri Foam Solutions, we customize open-cell or closed-cell systems to improve comfort and lower energy bills across New Orleans and Baton Rouge.

Yes, spray foam can be applied to the ceiling of a vented crawl space or to the walls of an unvented one. For vented spaces, foam insulates between joists; for unvented designs, it seals walls and creates a conditioned environment. Both approaches reduce drafts, moisture risk, and improve indoor air quality in Louisiana homes.

Using fiberglass batts that sag, trap moisture, and allow air leaks. Fiberglass doesn't seal penetrations around ducts and plumbing, so humidity and pests get in. Spray foam fills every void and blocks vapor infiltration, which is critical in Louisiana's humid climate to prevent mold and floor system damage.

Closed-cell foam bonds directly to studs and sheathing, increasing racking strength and wall rigidity. Lab tests show foam-filled walls withstand higher wind loads before failure compared to fiberglass. At Tri Foam Solutions, we recommend this upgrade for homes in hurricane-zone areas like New Orleans and Houma to improve both insulation and storm resistance.

Yes, polyurethane foam is lightweight, durable, and cures quickly without adding stress to underlying soil. It's ideal for driveways, sidewalks, patios, and pool decks. The material fills voids, lifts slabs precisely, and provides long-term stabilization with minimal disruption—ready for use within minutes of application.

Seamless spray foam roofing has no traditional seams, eliminating leak points that fail during heavy rain or wind. The monolithic shell bonds fully to the substrate and handles ponding water and foot traffic. In Louisiana's storm climate, this durability and waterproofing make SPF roofing a smart choice for commercial and industrial buildings.
