Weather-resistant rock fiber panel developed for building exterior decoration systems. Manufactured from high-quality basalt fiber through high-temperature pressing, achieving Class A non-combustibility while exhibiting outstanding freeze-thaw resistance and moisture expansion resistance. Provides a strong, fire-safe, and durable base for exterior coatings, stone-like paints, and metal curtain walls.
Decorative substrate for exterior insulation finishing systems (EIFS) on high-rise buildings, commercial complexes, and industrial plants. Suitable for stone-like paints, fluorocarbon coatings, and other exterior finishes.
