Calcium Silicate is a non-asbestos lightweight
material available in sheet, pipe-section or
machined formats. Having a low density,
Calcium Silicate exhibits excellent thermal
insulation properties together with good
machinability and handling characteristics.
Its relatively low shrinkage makes it ideal for
use as secondary or back-up insulation in high
temperature applications such as furnace and
launder linings. Similarly, it is well suited as an
insulator in insulating lids and pipe supports.
Calcium Silicate is dusty by nature. To reduce dust,
the material can be coated with a Sodium Silicate
solution before using. When being machined,
Calcium Silicate gives off large amounts of dust;
suitable extraction equipment and protective
clothing should be used.
Other benefits include:
Low thermal conductivity
Autoclaved Calcium Silicate board, reinforced with Cellulose Fibres.
