Insulating Fiber

Superwool® Plus™ high-temperature fiber insulation is ideal for repairing and lining aluminum furnaces, and it reduces the frequency of relining operations when compared to the industry standard. Improved insulation efficiency also results in decreased operating costs. Superwool Plus has been engineered to maximize the fiber content. As a result, its insulating fiber has up to 20% lower thermal conductivity than competitive fiber insulation materials. The maximized fiber content reduces radiant heat transfer, making Superwool Plus insulation an excellent choice for lining heat-treat furnaces for aluminum and other nonferrous metals and homogenizing furnaces for aluminum casters. Superwool insulating fibers are also non-wetting to molten aluminum. This reduces the concerns about metal adherence and penetration into the fibers.
