Vertical silk rock wool

★ Taishi vertical silk rock wool thin plastering system products are designed and produced specifically to improve the fire resistance of the building's external wall insulation system. This product is used by cutting the horizontal silk rock wool board according to the required thickness and turning it 90°. The fiber direction is perpendicular to the base wall. It has high drawing and compression strength. It is especially suitable for thin plaster external wall external insulation systems. It can also be matched with insulation materials whose outer walls cannot reach Class A fire protection, and used as a fire isolation belt to increase the overall fire protection capability of the building's outer walls. 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.

Typical application

1. Used for thin plastering exterior wall thermal insulation system, the fiber direction is perpendicular to the surface of the base wall to improve the tensile and compressive capabilities of the system.

2. It can be used as a fire isolation belt with non-A-grade fire insulation materials such as polystyrene board and extruded plastic board to improve the fire protection ability of the external wall insulation system.


Packaging and storage

Rock wool strips are packaged in pallets and plastic films, 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.
