Insulating boards


The insulation boards are manufactured from aqueous suspensions of refractory fibers using the vacuum-forming method. The precisely selected layout of binders allows for the use of a minimal amount of (non-toxic) organic elements. They are removed during the first annealing, from the temperature of approximately 250 °C. As a result the board becomes completely odorless and returns to the white color. In terms of the classification temperature, we manufacture two types of boards: 1260 °C and 1430 °C.

With concern for our products, shipping of insulation boards is performed only on pallets.
