YANTAI HUAMEL ENERGY_SAVING CONSTRUCTION MATERIAL CO.,LTD.is specialized in providing new supporting insulation materials.
Main production ：Glass Wool、Extrusion Molding、Rubber And Plastic、Rock Wool、Aluminum Silicate、Polyurethane
Product description
The special rock wool strip for external wall insulation and fire isolation belt is designed and produced specifically to improve the fire resistance of the building's external wall insulation system. This product is matched with thermal insulation materials that cannot reach Class A fire protection on the outer wall, and is used as a fire isolation belt to increase the overall fire resistance of the building's outer wall. It has the advantages of high compressive and tensile strength, low water and moisture absorption, good dimensional stability, aging resistance, and no thermal expansion or shrinkage.

The above data is for reference only. The company reserves the right to improve product performance with the improvement of production equipment and technology.
1. It can be used as a fire isolation belt with non-A-class fire insulation materials such as polystyrene board and extruded board to improve the fire protection ability of the external wall insulation system.
2. Used for thin plastering external wall insulation system, the fiber direction is perpendicular to the surface of the base wall to improve the tensile and compressive capabilities of the system.
Rock wool slivers are packaged in pallets and plastic film, or in cartons, and they can also be bundled to facilitate handling, transportation and storage. The product should be stored in a dry, ventilated room or covered with waterproof material.
