Refractory & Insulation Supply, Inc. has been a leading supplier of refractories and refractory services since 1979. Based out of Eldridge, IA, we provide precast shapes, and installation services to the entire country as well as Mexico and Canada.

Insulating refractories include calcium silicate materials, kaolin, and zirconia. Insulating refractories are used to reduce the rate of heat loss through furnace walls.

Whether the furnace maintains a constant temperature or experiences cycles, a refractory insulation package is crucial to curbing fuel consumption and regulating cold face temperatures. Insulation materials like boards, fibers, bricks, and castables offer diverse options, each with distinct considerations like insulation effectiveness ...

Refractory lining provides a protective layer inside the equipment as a form of insulation for elevated temperature services. The refractory lining withstands high temperatures, thermal shock, wear, and chemical corrosion.

discussion of insulating refractories, their types, raw materials, manufacturing, properties and applications etc., here we will first review some of the fundamental technology of high- temperature insulation.

Information on refractory materials and high-temperature insulation materials - material groups (refractories, IFB, HTIW, Calciumsilicate, microporous insulation), properties and use

Refractory insulation can be used to insulate industrial boilers, furnaces, and other high-temperature equipment. Distribution International offers a wide range of refractory & ceramic fiber products like refractory modules, anchors, & bricks and ceramic fiber blankets and boards.

The size and uniformity of these pores directly affect both insulation performance and material strength; smaller pores generally result in better insulation. Lightweight refractory materials typically exhibit thermal conductivity values below 1.0 W/(k·m) (600℃×3h), while semi-lightweight materials are generally below 1.26 W/(k·m) (600 ...

We carry an assortment of thermal insulation materials, from our Nu-Board mineral fibers to our J-3000 refractory mortar. Our thermal insulation products ultimately work to combat the negative effects of consistently high temperatures.
