product details
• DESCRIPTION
Low Density Calcium Silicate Boards are lightweight insulation boards made from inorganic mineral or cellulose fibers reinforced with silica-calcium materials. Through pulping, molding, and high-temperature, high-pressure steam curing, they form a stable calcium silicate structure with excellent fire resistance, moisture resistance, sound insulation, durability, and insect resistance.
These calcium silicate insulation boards are widely used for ceilings, partitions, wall insulation, and industrial equipment insulation. As an experienced Low Density Calcium Silicate Board Manufacturer, Mindelun offers different densities, thicknesses, and sizes. When comparing silicate calcium board price, density, dimensions, quantity, and performance requirements should all be considered.
• PROPERTIES
