Transite HT

These non-asbestos, monolithic, fiber cement industrial boards are used where high strength is the primary concern.


The 3R4080 is used in the foundry industry for flask liners, cores, drying and carry plates, and induction furnace casings. Electrical applications include busbar supports, aluminium pot insulation, and electrode arm insulators.

Transite HT is also used as load bearing gasketing, spacers, supports, and machined parts for OEM applications.
