Building rock wool board has excellent fire protection, thermal insulation and sound-absorbing properties. Rock wool board is mainly used for building walls, noise insulation of the roof; building wall, firewalls, fire doors and elevator shafts, fire protection and noise reduction. Characteristics of wool board, rock wool board appearance quality: smooth surface, and shall not hinder the practical scars, smudges damaged. 2, combustion performance: non-combustible rock wool board. 3, rock wool board heat load contraction temperature: 643 degrees. 4, rock wool board moisture absorption: 3.9%. Performance fireproof rock wool board: the color composite sandwich panel surface materials and insulation materials for non-combustible material, fully able to meet fire code requirements. Durable: a variety of studies have shown, and and abroad widely use for more than 40 years confirmed that a special coating color steel shelf life of 10-15 years, and every 10 years after the spraying anti-corrosion coatings, plate life of up to 35 years. Beautiful: clear lines of steel sheeting as many as dozens of kinds of colors, can be used with any style buildings demand, to achieve satisfactory results. High strength: high strength steel the substrate (tensile pull strength 5600KG/CM) coupled with the most advanced design and roll forming, has excellent structural properties. Composite board insulation: Rock wool board commonly used insulation material: rock wool, fiberglass, polyethylene, polyurethane, low thermal conductivity, good insulation effect.
