Closed-cell spray polyurethane foam (ccSPF) offers significant structural benefits due to its rigid nature and strong adhesion to various materials. When applied to framed buildings, even just 2-3 inches of SPF can substantially increase the racking strength of certain walls and the uplift strength of framed roof decks. For more detailed information on these structural enhancements, we recommend contacting the Spray Polyurethane Foam Alliance (SPFA) at www.sprayfoam.org. If you're considering spray foam roofing for your property, our team would be pleased to discuss how these structural benefits could apply to your specific situation.

Closed-cell spray polyurethane foam (SPF) is designed to repel water rather than absorb it. This water-resistant quality has led to its approval by FEMA as a flood-resistant material. While it doesn't absorb water, SPF does have a low vapor transmission rate. This property allows the roof to 'breathe,' preventing moisture from accumulating beneath the foam surface. If you're interested in learning more about how these properties could benefit your roofing system, our team would be happy to provide further information.

Spray foam is not considered toxic once it has fully cured. In our experience with spray foam roofing and similar applications, any potentially hazardous fumes typically dissipate within 24-48 hours of application, provided there is proper ventilation. After this period, the cured foam is generally safe for occupants.

Spray polyurethane foam (SPF) can indeed function as an effective air barrier when applied to certain minimum thicknesses. For closed-cell foam, this is typically about 1.5 inches, while open-cell foam requires 3.5-5.5 inches. When properly installed as part of a well-designed building envelope, SPF plays a crucial role in creating air barrier assemblies and systems. For more comprehensive information on air barriers, we recommend visiting the Air Barrier Association of America (ABAA) website at www.airbarrier.org. The ABAA provides a material specification for SPF under their document 07263. Our team can provide guidance on how to incorporate this type of barrier into your roofing system using spray foam.

As spray polyurethane foam (SPF) is combustible, model building codes typically require it to be separated from occupied spaces by a 15-minute thermal barrier, such as -inch gypsum board or drywall. In areas with limited access like crawlspaces and attics, an ignition barrier may be permitted instead of a thermal barrier. The model building codes define prescriptive thermal and ignition barriers, but alternative coatings, coverings, and assemblies may also be used. For more detailed information on these fire protection measures, we recommend reviewing the SPFA guideline AY-126, available in the Technical Documents section at www.sprayfoam.org. If you have any specific questions about fire protection for your spray foam roofing project, our team is ready to assist you.

A spray polyurethane foam (SPF) roofing system is a versatile solution that can be applied over various substrates including concrete, wood, metal, and even failed built-up or single-ply roofs. The process begins with thorough cleaning and preparation of the roof deck. Then, a layer of SPF is applied as a liquid, which rapidly forms a solid, closed-cell membrane through a chemical reaction. This application method allows for customizable thickness to enhance insulation, create positive slopes, or eliminate water ponding areas. The seamless nature of SPF eliminates potential water entry points and thermal shorts, which can significantly improve energy efficiency. The foam is then protected by two coats of elastomeric coating and granules, creating a durable, weather-resistant membrane. This system is self-flashing and can be applied to vertical surfaces for a homogenous finish. Only highly skilled, qualified applicators can install this system, and each application is inspected by an independent engineering laboratory to validate the warranty. Our SPF roofing systems are Energy Star approved, LEED certified, UL rated, FM certified, Miami-Dade County approved, and compliant with California Title 24.
