Note: This is a variation of Ultratemp – Calcium Silicate Insulation Boards.
Ultratemp 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 1/2″ 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 stability
- Consistently low thermal conductivity
- High structural strength at elevated temperatures
- Incombustible
- Electrical insulating properties when dry
- Easily machinable
- Insoluble in water and non-corroding
