• DESCRIPTION
Mindelun stone wool board(rock wool board) made from high quality basalt materials and use advanced production process, making it versatility and compatibility with various external wall insulation systems, and keep its ever lasting thermal, acoustic and fire insulation properties.
• PROPERTIES
Ø High thermal insulation.
Ø Good hydrophobicity&moisture resistance.
Ø Good Sound absorption .
Ø Non-corrosives, Lasting dimension stability.
Ø Safety and ECO friendly.
Ø Easy construction.
• APPLICATION
Ø Wall insulation: The rock wool board or rock wool felt is embedded between interior and exterior walls or on exterior surfaces to reduce heat transfer and improve the insulation effect.
Ø Roof insulation: Laying rock wool felt or board under the roof structure to block heat and ensure a comfortable indoor temperature for building.
Ø Floor insulation: Install rock wool at the bottom of the floor to reduce the heat and cold conduction of the floor and improve its thermal insulation performance.
Ø Insulation of pipelines and equipment: Covered the rock wool on the surface of pipelines and equipment to reduce energy loss and ensure their normal operating temperature during using.
