Significant on applications involving cements and mastics. Significant when constructing a sound barrier. The following is a general inventory of the characteristics and properties of major insulation materials used in commercial and industrial installations. See the Insulation Property Tables at the end of Section II for a comparative review. Flexural strength is good.
Calcium silicate is water absorbent.
However, it can be dried out without deterioration. The material is noncombustible and used primarily on hot piping and surfaces. Jacketing is field applied. Available as flexible blanket, rigid board, pipe insulation and other pre-molded shapes. The product is noncombustible and has good sound absorption qualities.
