INSULATION CASTABLES & GUNNING MIXES
VITCAST 1200INS & GUN MIX Very lightweight backup insulation castable. Typically used between the outer casing and lining in boilers, flues / stacks and low temperature applications where a lightweight material is required.
VITCAST 1250INS & GUN MIX Lightweight insulation castable – denser and stronger than 1200INS which can be used in sub-floor applications such as in brick kilns and kiln car bases.
