temp boards are inorganic, incombustible Calcium Silicate structural insulation boards. They feature a xonalite structure that results in exceptional strength and extremely low water of hydration. The materials are composed primarily of lime, silica, and reinforcing fibers. The product is white, essentially dust-free, and contains no asbestos. Ultratemp is available in thicknesses from 12" to 3" in 48" x 96" sheets, or cut-to-size as needed. Ultratemp materials should be specified when the following properties are required:Thermal shock resistance and stabilityConsistently low thermal conductivityHigh structural strength at elevated temperaturesIncombustibleElectrical insulating properties when dryEasily machinableInsoluble in water and non-corroding
