Products

Refractories

Furnace, kiln and boiler materials rated from 1000°C to 2000°C — brick, castables, mortars and ceramic fibre.

A refractory lining is a system rather than a single product: a dense hot face that takes the heat and the chemistry, insulation behind it to keep the heat in, and the mortar, castable and fibre that tie the two together and seal the gaps.

We supply the whole system — alumina and zirconia brick from general duty to 2000°C, dense and insulating castables, jointing mortar, and ceramic fibre in blanket, board, rope, tape and cloth form.

Typical applications

Furnace and kiln linings
Boiler and incinerator refractory
