Steel Fashion Mineral Rook Wool

+ High degree of resistance to fire. + Cool design with thermal insulation. + Sound proof and watertightness. Rock Wool Sandwich Panel Metal panel insulated with rock wool for roofs and walls which require a high degree of resistance to fire. The panel is constituted by two sheets with inter posed layer of orientated fibre high density rock wool, and Rook wool is non-combustible material, so the rock wool panel has good fire-resisting property. The test shows temperature of the panel fire-proof is as high as 1000C. Characters 1. Fire performance: Rock cotton core material for non-combustible material, has more than 1000° C temperature of melting in the fire, can be effective blocking flame spread, aximum limit reducing fire losses. 2. Heat preservation and heat insulation: Rock wool low thermal conductivity(lambda=0.043W/m larecaille k), thermal insulation performance is good. Excellent node design to ensure the sealing performance and the heat preservation effect. 3. Sound insulation good: Sound insulation of sound insulation is 30dB, effectively reduce experiment it outside noise interference. 4. Watertightness/air tightness: Between plates into unique design chimeric type node, to stop the invasion of the water, the board at the end of the connection, internal closed processing, keep good air-tightness. 5. Durable: Selects high quality rock wool materials, hate water rate is old, lasting firm. 6. Tight & joint, no cold bridge, screw concealed and great design.
