1.2.1 Castables Gunning materials Castable and gunning material is not vacuum sealed some moisture is included during packaging this limits the lifetime of the material in general. For maximum shelf life the following measures are recommended • Material should be kept in dry location during storage • Bags of castables and gunning

Castables Hasle Refractories

From an application point of view insulating castables are competing with insulating (porous) bricks. An insulating castable is suited as filling material between e.g. a high refractory lining and block insulation. The insulating castable flows into all corners and cracks and leaves no cavities. Besides it is easy and uncomplicated to handle.
