The above figures are only for reference. With the development of the production facility and technology, we reserve the right to improve our product performance.
1. The product can be matched with polystyrene board, extruded sheet and other Non-combustible grade A insulation materials together ,which can be used as a fire barrier, improving the fire resistance of external wall insulation systems.
2 .The product can be used for exterior wall insulation materials and make the fiber direction perpendicular to the primary wall surface, improving the tensile strength, compressive strength.
3．The product can be used for fireproof, waterproof, thermal insulation, sound insulation requirements in the higher places as the core material of the metal sandwich board
Packaging and storage:
R ock wool strip should be packed with the rock wool trays and plastic film .it also can be bundled .so that it is convenient to transport and storage. Products should be stored indoors or covered with a waterproof material .
