Fire Retardant
A-Grade (A1 & A2)
A-Grade includes A1 and A2 materials, both classified as non-combustible. With 90% mineral composition, it completely blocks fire from spreading.
A2 material gives off minimal heat, no smoke, and produces zero flaming droplets.
B1 Grade
B1 materials are fire-retardant with low flammability. Designed to stop fire from spreading quickly. With 70% inorganic mineral content, it generates only a small amount of heat and smoke.
B2 Grade
Moderately flammable fire-retardants. These are not truly “fireproof” but are designed to reduce flame spread and self-extinguish once the flame source is removed from contact.
