BLOCK

BLOCK

D-BLOCK is made of stacked multiple layers of BLANKET which are sewn together under compression. This product has superior uniformity, resilience and dimensional accuracy. There are 6 kinds of D-BLOCK according to the temperature conditions of various industrial furnaces. Isowool BSSR UNIBLOK is made of stacked multiple layers of AES (Alcaline Earth Silicate) wool which are modularized under compression.
In addition, various support brackets are prepared according to the construction conditions. (Please refer to here for inorganic adhesives, surface coating materials and so on.)
