ISOWOOL Uniblok and Saber Bloc
| Features |
ISOWOOL Uniblok and Saber Bloc are ceramic fiber blocks made of ISOWOOL Blankets. The Uniblok is the cut-and-layered type while the Saber Bloc is the folded type of the stack of blankets. The cubic structure greatly saves the installation time. Hybrid Uniblok 15A, a block made of ISOWOOL 1500 fiber with equally-spaced alumina fiber to have excellent features of spring-back, prevention of the damage centered on joint sections, thermal stability is an ideal lining material for the furnaces being operated at high temperatures and under rapid repetitions of heating and cooling. |
