Morgan Advanced Materials (Morgan) announces the availability of Superwool® Pyro-Bloc® modules for furnace and boiler lining systems, produced by its Thermal Ceramics business. The modules are manufactured in Asia, Europe and the newly commissioned North American production line in Emporia, Kansas. The new production capability allows Morgan to better support its offerings in Pyro-Bloc modules utilizing the Superwool low bio-persistent, high temperature fiber insulation technology.


The market leading Pyro-Bloc modules have set the standard for quality and versatility in furnace and boiler lining systems since their market introduction over 30 years ago. The only monolithic ceramic fiber modules on the market, Pyro-Bloc modules combine the insulation advantages of ceramic fiber with rapid furnace installation. Compared to standard folded modules, Pyro-Bloc modules feature higher density, better tolerance compliance, and superior resistance to erosion from high velocity gas. Pyro-Bloc modules are ideal for such applications as stack, flare and ductwork linings, as well as kiln car block and seals, burner blocks and peep sights.

Morgan's Alkaline Earth Silicate (AES) fiber composition, marketed as Superwool, is available in densities of 10 and 12 pounds per cubic foot (160 and 192 kilograms per cubic meter). The Superwool Pyro-Bloc modules are offered in two temperature classification grades: Superwool Plus (2192°F) and Superwool HT (2372°F).

Due to Superwool's low shot content, the thermal conductivity of Superwool Pyro-Bloc modules, is typically 10-15% lower than like-density Refractory Ceramic Fiber (RCF) modules. In addition, improved heat storage properties result in gas/energy savings and an improved work environment by lowering the skin temperature of furnaces and boilers. 

Superwool HT Pyro-Bloc modules have high dimensional stability up to the classification temperature, critical for furnace and boiler applications where reduced linear shrinkage is important to longevity.

Pyro-Bloc Modules are installed with compression in both the vertical and horizontal direction, thus allowing designers to eliminate unsupported overhead battens and packing strips. In addition, the unique monolithic module structure of the modules decrease the number of through joints required by folded module systems; they can also be installed without a stainless steel shroud, adding to their ease of installation.

Superwool Pyro-Bloc modules monolithic edge grain surface is more resistant to high velocity gas erosion than folded systems. Along with erosion resistance, the module surfaces will more readily accept any required post treatments due to the grain of the fiber, which allows a deeper penetrating bond of the substrate. Several such treatments are available, some improving velocity resistance up to 35%.
