Fire Safety in Solar Solutions: Understanding Mitrex’s Fire Ratings and Compliance

Fire Safety in Solar Solutions

Whether you’re a developer in Los Angeles, a building owner in New York City, or a project manager breaking ground in Chicago, using high-quality, tested materials is not optional—it’s essential. Fire safety codes in these cities are some of the strictest in North America. That’s why Mitrex BIPV isn’t just energy-generating and cost-saving—it’s certified, compliant, and ready to meet your local jurisdiction’s requirements head-on.

Fire Safety Starts at the Façade

In building construction, fire safety isn't just about suppression—it begins with material choice and system design. When it comes to exterior wall assemblies, ensuring fire-resistant cladding is essential to prevent vertical flame spread from floor to floor. For developers and architects working on commercial towers and mixed-use buildings, this is where Mitrex’s Building-Integrated Photovoltaics (BIPV) stand out.

In-Depth Certification Standards and Testing

Mitrex BIPV systems undergo rigorous testing to meet or exceed major international fire safety standards:

  • NFPA 285: This is the industry benchmark for testing vertical fire spread in multi-story buildings. Mitrex cladding is tested as part of a full assembly to demonstrate fire resistance in real-world scenarios.

  • CAN/ULC-S135: Ensures flame spread and smoke development indexes are within safe limits for Canadian code compliance.

  • EN 13501-1: European standard used globally to classify reaction to fire performance in external wall cladding systems.

These certifications confirm that Mitrex BIPV can be safely integrated into code-compliant commercial construction.

Mitrex Materials: Engineered for Containment

Mitrex solar-integrated facades are built using flame-resistant materials designed to inhibit ignition and contain fire spread. Unlike standard cladding or combustible exterior systems, Mitrex BIPV products are engineered as part of fire-rated assemblies that mitigate fire risks in mid- and high-rise buildings.

Real-World Application in Code-Sensitive Markets

In some of the most regulation-heavy cities in North America—including San Francisco, Los Angeles, New York City, Chicago, and Boston—compliance with fire testing standards like NFPA 285 is a core requirement for façade system approval. In these urban markets, where mid- and high-rise commercial developments dominate, developers must submit full assembly test documentation as part of the local permitting process. Mitrex’s detailed documentation package, tested assemblies, and support services help simplify approvals for building departments, and code consultants.

Supporting Compliance with Clear Documentation

Mitrex provides a full suite of technical documentation to assist in code reviews:

  • NFPA 285 assembly testing reports

  • Connection details and construction drawings

  • Third-party certifications

  • Alignment with green building programs including LEED, BREEAM, and ENERGY STAR

These materials help streamline the approval process while supporting both safety and sustainability objectives.

Certified for Use in Commercial Developments

One example of Mitrex's commitment to code-compliant construction is the ongoing SAMIH project in Toronto, Ontario. This high-performance, university development is being outfitted with Mitrex solar-integrated facades that comply with rigorous fire safety codes. As a showcase of energy-generating architecture that meets strict local building requirements, the University of Toronto SAMIH building illustrates how Mitrex supports sustainable growth across the most regulated construction environments. This extends to places like Los Angeles, San Diego, New York, Chicago and across the world. 

Mitrex BIPV systems are built for performance and safety in:

  • High-Rise Towers: Fire-tested facade systems that meet strict regulatory codes.
  • Mixed-Use Commercial Buildings: Enable energy generation and visual impact without compromising safety.

Long-Term Durability and Minimal Maintenance

Designed for durability, Mitrex BIPV cladding maintains performance with minimal upkeep:

  • Resistant to weather, temperature extremes, and UV exposure

  • 25-year performance warranty

  • Built-in monitoring systems for energy output and operational reliability

Mitrex’s Commitment: Safety by Design

At Mitrex, fire safety is built into the product—not added on as an afterthought. By designing systems that comply with NFPA 285 and other major standards, Mitrex enables developers and architects to meet safety codes while achieving beautiful, energy-generating facades.
