Calcium Silicate Insulation

Thermal conductivity of calcium silicate insulation - temperature and k-values.

Calcium silicate is used as a safe alternative to asbestos for high temperature insulation materials.

Features of Calcium Silicate insulation board and pipe insulation are

  • light weight
  • low thermal conductivity
  • high temperature and chemical resistance

Calcium Silicate is a rigid, high density material suitable for high temperature applications ranging 250 oF (121 oC) - 1000 oF (540 oC).

Calcium Silicate thermal conductivity related to temperature are indicated in the charts below:

Calcium silicate Themal conductivity - Metric units

Calcium silicate Themal conductivity - Imperial units

  • compressive strength is good
  • noncombustible

 

  • T(oC) = 5/9[T(oF) - 32]
  • 1 W/(m K) = 6.935 (Btu in)/(h ft² °F)
