Fire-resistance

Fire resistance is an important consideration when it comes to selecting materials for any commercial project. Many jurisdictions mandate fire safety codes, particularly for public and commercial spaces.

Polygood® panels have achieved different fire-resistance Euroclass ratings depending on their application and treatment. This information is crucial for specifiers who need to select materials that comply with fire safety regulations. 

Flooring applications 

Polygood® panels with an FPCC coating achieve a Euroclass rating of B(fl), s1, according to standard EN 13501-1. This indicates moderate flammability with a low smoke development.

Construction products

Construction materials (excluding flooring) have the following ratings according to EN 13823:2020 standard, as a part of classification standard EN 13501-1.

• Untreated Polygood Panels: These achieve a base Euroclass rating of E, s3-d0. This signifies limited combustibility with high smoke development and no flaming droplets.
• Polygood Panels with Special Fire Retardant Coating: These panels achieve a Euroclass rating of E, s3-d0. While the classification is the same as untreated panels, the test results show a 2.5 times better performance in fire resistance (according to test reports).
• Polygood Panels with Special Technology (limited patterns): These panels offer a higher fire-resistance Euroclass rating of D, s3-d2. This translates to limited combustibility with high smoke development and some flaming droplets.

While Euroclass is the European Union standard, we have also achieved an M3 rating for M classification — the French standard for a material’s reaction to fire.
