Insulating Material

Insboard

Ceramic insulating fiber boards are low density products ranging from 12 lbs. per cubic foot to 45 lbs. per cubic foot. They can be used in applications exceeding 2300° F . For many hearth applications, insboard is essential in providing a protective barrier against combustible materials.

Inswool

Ceramic insulating fiber wool blankets are used for anchor plate applications providing an air or gas tight gasket seal between Isokern top plates and metal chimney anchor connections.

Our insboard and inswool products can be used in such applications as:

  • Full thickness refractory lining (insboard)
  • Insulating backup refractory (insboard)
  • Hot Face lining with no moisture present (insboard)
  • Gaskets and seals (inswool)
  • Flue and duct linings (inswool)
  • Infra-red and electrical element support (insboard)
