Rigid/Semi-rigid Water-repellent Rockwool Insulation Boards It's made from natural rocks such as basalt and limestone.The rocks are melted in a cupola and the molten lava is fiberized by a spinner. The inorganic fibers are bonded together using a thermosetting resin to form the final product which is cut into suitable sizes for easy handling and installation. Finds its way into thousands of residential and commercial buildings as well as into industrial and OEM applications.     ♦Rock mineral wool slab products offer a wide range of benefits, and can be used in an equally wide range of applications. ♦Rock mineral wool slabs offer exceptional fire performance characteristics, as well as excellent thermal and acoustic properties. ♦SA products further improve upon the benefits of slabs by being scientifically designed and manufactured to provide a very high level of compression resistance   The fibres are aligned in such a way as to dramatically increase the ability of the slab to resist heavy loads while maintaining the thermal, acoustic and fire performance Other properties of rock mineral wool insulation:  vapour permeable ( " breaths" )  fire protection insulation  resistant to aging and decay ( long living )  resistant to micro organisms and insects  resistant to chemical substances  chemically inert and completely recyclable with an ecological production process TYPICAL APPLICATIONS Flat roofs Membranes Suspended ceilings Insulation with an extra high fire classification in addition to wood wool (application underground parking).   External walls Contact and ventilated      Internal and partition walls Insulation with an extra high fire classification Floors Load bearing - impact sound insulation.   Insulation of industrial (power and chemical) plants With wired mats (and facade lamella mats) used in thermal and acoustic insulation for industrial work, pipe sections, and air ducts.
