MCM Flexible Stone Fire Safety & Compliance — Knowledge Center

Overview

Fire performance is non-negotiable for cladding and façade materials. TooFlexi MCM flexible stone is tested to A2 class under GB 8624 (limited combustibility), with the test report issued under the manufacturing entity’s name and available on request for project submittals.

For projects that require a European or Middle Eastern classification, our panels can be specified to meet EN 13501-1 requirements, with classification evidence provided through the factory’s documentation. This hub collects the fire-safety guide, the A2 compliance deep-dive, the certification reference and the regional fire-code guides most used on compliant projects.

Before specifying, also review the technical specifications and the installation system, since fire performance depends on the full assembly, not the facing alone.

What “A2 Class (GB 8624)” Means

GB 8624 is the Chinese national standard for the classification of burning behaviour of building materials. Class A2 sits in the limited-combustibility tier: the material shows limited combustibility and contributes little to fire growth. TooFlexi MCM reaches A2 under GB 8624 based on testing carried out and reported at the manufacturing facility.

Because the report is issued under the manufacturer’s name, we describe the product as “A2 class (GB 8624), factory tested” rather than claiming a brand-level certificate. The documentation can be shared with architects, consultants and approving authorities during submittal.

Aligning With International Fire Codes

Many markets reference their own reaction-to-fire systems. The table below maps common regional frameworks to how TooFlexi panels are positioned. We describe the market requirement and state our actual evidence — we do not claim certificates we do not hold.

Note: standards such as ASTM, NFPA 285, AS 1530, GOST and SASO are referenced by regional codes; TooFlexi does not currently hold test reports to those specific standards, so project-specific evidence should be discussed with our team.

Why Assembly Matters

Reaction-to-fire rating describes the facing material. Real-world façade safety also depends on the full build-up — adhesive, mesh, substrate, cavity barriers and fire-stopping at floor lines. Specify MCM as a documented system and coordinate perimeter firestops with the façade engineer.

Frequently Asked Questions

Is TooFlexi MCM fire-rated?

Yes — it is tested to A2 class under GB 8624 (limited combustibility), with the test report issued under the manufacturing entity and available on request.

Do you have EN 13501 or CE certification?

We do not hold a brand-level EN 13501 or CE certificate. Panels can be specified to meet EN 13501-1 requirements, and we hold verified EN 15102:2019 and EN 15286:2013 certification under CPR (EU) 305/2011 (certificate ICR/VC/HGS260321).

Can it be used on high-rise façades?

A2 (GB 8624) limited-combustibility performance supports specification on tall buildings; final acceptance depends on the local authority and the complete façade system. Discuss your project with our team for submittal support.
