A Smarter, Greener Future for SPF Roofing: Making the Switch from HFC to HFO Spray Foam
In the evolving world of spray polyurethane foam (SPF) roofing, the shift from hydrofluorocarbon (HFC) blowing agents to hydrofluoroolefin (HFO) technology isn’t just an environmental milestone—it’s a performance upgrade.
At Rugged Coatings, we specialize in manufacturing advanced acrylic and silicone roof coatings designed to enhance and protect SPF systems. And when it comes to the foam beneath our coatings, we partner exclusively with Accufoam, a trusted name in spray foam innovation, for our comprehensive Rugged Roofing System. Our HFO-based roofing foam plays a pivotal role in delivering energy-efficient, applicator-trusted, and environmentally responsible roofing systems that stand up to the demands of real-world performance.
Below, we’ll explore why the transition from HFC to HFO matters, how it affects SPF roofing applications, and what contractors can expect when installing the next generation of sustainable roofing systems.
The Push for HFO: Environmental and Regulatory Drivers
Historically, HFCs have been used as blowing agents in spray foam insulation. While effective, these compounds have an elevated global warming potential (GWP), making them targets for global environmental regulations. With legislation like the American Innovation and Manufacturing (AIM) Act and similar international mandates, the industry is under pressure to reduce HFC use in favor of more sustainable alternatives.
Enter HFOs: These next-generation blowing agents deliver the same closed-cell insulation properties and dimensional stability of HFCs but with ultra-low GWPs. For contractors, this means compliance with evolving building codes and environmental regulations, without sacrificing the performance their clients demand.
HFO Foam Performance Benefits
While the regulatory advantages of HFO foams are clear, they also offer several performance enhancements that matter on the job site:
- Superior Sprayability: HFO foam formulations often exhibit better control during application, reducing issues like off-ratio spraying and overspray.
- Consistent Yield: Due to their refined chemistry, HFO-based foams deliver consistent rise and cure rates, leading to more predictable yields and minimized waste.
- Improved Aesthetics and Adhesion: The smoother texture and tighter cell structure of HFO foams create an ideal surface for roof coatings, improving long-term adhesion and finish.
Accufoam: Optimized HFO Roofing Foam Backed by Research
Accufoam’s transition to HFO wasn’t a simple reformulation. It was a complete reengineering of our foam systems, built from the ground up with contractors in mind. As the exclusive provider of roofing foam for Rugged Coatings’ Rugged Roofing System, Accufoam’s HFO product reflects a deep commitment to product quality, application efficiency, and jobsite reliability.
Our research and development team spent years working directly with applicators to fine-tune key characteristics:
- Spray Pattern Control: Accufoam HFO offers a tight, uniform spray pattern that helps crews apply foam faster and more evenly.
- Hot and Cold Climate Compatibility: Whether you’re spraying in high humidity, early, or late season conditions, Accufoam HFO maintains stable performance.
- R&D-Backed Consistency: Every batch is rigorously tested to ensure consistency in density, cell structure, and cure time, so contractors know exactly what to expect.
For contractors, this means less downtime, fewer jobsite surprises, and better overall performance.
Why It Matters for Coated SPF Roofing Systems
SPF roofing systems rely on the synergy between the foam layer and the protective coating that seals and protects it. That’s where Rugged Coatings comes in—our acrylic and silicone roof coatings are designed to work hand-in-hand with high-performance SPF, and Accufoam HFO foam ensures a solid foundation.
An optimized foam surface leads to better coating adhesion, which means:
- Fewer re-coats and touch-ups
- Longer system life
- Improved waterproofing and UV protection
By switching to HFO foam, contractors are not only complying with regulations—they’re giving their clients longer-lasting, more durable, and more sustainable roofing systems.
Better Foam. Better Roofing.
At Rugged Coatings, we know that every part of a roofing system matters. That’s why we only align with partners who share our commitment to performance, innovation, and environmental responsibility. Accufoam’s HFO-based roofing foam is a direct reflection of those values.
For contractors ready to stay ahead of regulations, improve application efficiency, and deliver more reliable results, HFO foam isn’t just the future—it’s the now.
