  JYT Calcium Silicate Board and Pipe Cover high temperature insulation is manufactured using an industry preferred filter press method which provides accurate
dimensional tolerances and superior compressive and flexural strength.
These attributes facilitate installation and provide exceptional resistance to mechanical abuse.
JYT calcium silicate insulation is asbestos free and meets or exceeds all of the requirements of ASTM C 533, Type I.
  JYT calcium silicate insulation is recommended for use on equipment and piping operating at temperatures from ambient to indoors and protected outdoors up to 650℃. It is ideally suited for industrial use in areas such as
the petrochemical and power generating industries where energy conservation, process control, personal protection and fire protection are prerequisites.
  JYT calcium silicate board and pipe cover insulation are available.
