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.



Our insulating boards are used as wall coverings, linings for combustion chambers, boiler linings, dilatations, insulation, etc. For each order we come individually. Examples of using boards are in GALLERY.
