Calcium Silicate Bricks

Calcium Silicate Bricks

CALCIUM SILICATE THERMAL INSULATION
Slab, Lags, Bricks, Pipes & Powder up to 1000 0C

Insulation brick based on Calcium Silicate is reacted Calcium Silicate containing reinforcing fibers (non-asbestos). It offers thermal efficiency of flexible insulation like mineral wool and strength of conventional Insulation Bricks.

Insulation pipes are ideal replacement for fibrous insulation and are un-matched in places where insulation is exposed to water, floor traffic, and impact loads etc.

Insulations based on Calcium Silicate meet specifications as under: –

  • IS 8154 & 8428
  • Relevant Naval Specifications
  • ASTM C 533-90
  • B.S.3958 part II.

Advantages:

  • Low Thermal Conductivity
  • Rigid & Light Weight (Density 250 kg/M3)
  • Good Mechanical Strength (Above 10kg./cm2)
  • Fire Resistant
  • Low shrinkage
  • Low specific Heat
  • Non Combustible & Non Corrosive
  • Low Maintenance Cost
  • Re-usable & Long life
  • Easily Workable (cuts easily)
