Refractory Insulation/Thermal Insulation

Thermal insulation, much like our other fireproof materials, is a commodity for applications in stoves, boilers, ducts, welding pads and kilns. We carry an assortment of thermal insulation materials, from our Nu-Board mineral fibers to our high-temperature tadpole gaskets and seals. Our thermal insulation products ultimately work to combat the negative effects of consistently high temperatures. As with everything in our product line, IEP offers fabrication services to customize all our refractory insulation and thermal insulation.

Alumina-Silica Ceramic Fiber

  • Alumina-silica ceramic fiber with thermal insulating properties. Can be used in 2300°F temperatures with little physical change to the material (rope, board, paper, fabric, tape, and by the reel. Available in bulk quantities)
  • Excellent with a variety of applications like die cutting, furnace insulation, expansion joints, boilers and steam lines

Nu-Board

  • Available in original Nu-Board or Super Nu-Board
  • Both Nu-Board and Super Nu-Board have impressive thermal insulation properties. Original Nu-Board can withstand up to 1800°F and Super Nu-Board can withstand up to 2300°F

FAQs: Thermal Insulation Materials

In which industries is effective thermal insulation like R&R blankets and Nu-Board most critical, and why?

Industries such as power generation, metal processing, chemical manufacturing, and marine operations rely on high-heat systems where thermal insulation materials are essential for safe and efficient performance. Products like Alumina-Silica Ceramic Fiber blanket, a high-temperature refractory insulation, and Nu-Board, known for its strength and thermal shock resistance, are widely used in furnace linings, steam lines, and incinerators. These solutions help manage extreme temperatures, protect equipment, and support consistent operations in environments where dependable thermal insulation is a must.

How do Alumina-Silica Ceramic Fiber, Nu-Board, and R&R Blankets help reduce energy costs in industrial settings?

Alumina-Silica Ceramic Fiber, Nu-Board, and R&R Blankets are engineered thermal insulation materials that significantly reduce heat loss from high-temperature equipment. By creating effective barriers to thermal transfer, these refractory insulation products help maintain internal heat while minimizing energy waste. Whether you're lining a furnace with Nu-Board, wrapping steam pipes with Alumina-Silica Ceramic Fiber, or applying removable R&R Blankets to turbines or boilers, the result is improved thermal insulation, reduced fuel usage, and lower operational costs over time.

Why have R&R Blankets become a standard in the power, chemical, and marine industries?

R&R Blankets have become an industry standard due to their unique blend of flexibility, durability, and high-performance thermal insulation. Designed for repeated use without compromising protection, these thermal insulation materials allow for easy access to equipment while still delivering consistent refractory insulation properties. Their long-term performance in harsh environments has made them a go-to solution in the power, chemical, and marine industries, where operational efficiency and safe, reliable thermal insulation are top priorities.

How do I know which form of Alumina-Silica Ceramic Fiber to use?

Alumina-Silica Ceramic Fiber is available as a blanket, board, foam, paper, and in bulk fiber form, giving you flexibility depending on your application. For lining irregular surfaces or wrapping around piping, the blanket form offers excellent coverage and adaptability. The board and paper versions are great for die-cutting or creating tight-fitting components. All versions provide high-performance refractory insulation and are widely used in furnaces, boilers, and high-temp ducts. Our customer service team is glad to field any technical queries. Contact us!

Can Nu-Board or Super Nu-Board be customized for specific applications?

Yes, both Nu-Board and Super Nu-Board are easily die-cut, water jetted, machined, and sawed into custom shapes and sizes. Their dense yet workable structure makes them ideal for tailored thermal insulation applications, particularly in areas where precision and compression resistance are important.

Are these thermal insulation materials compliant with industry safety standards?

Yes, ceramic fiber blanket, glass matts, Nu-Board, and IEP R&R Blankets are engineered to meet the rigorous standards of industries like power, chemical, and marine. They are manufactured to withstand high temperatures and harsh environments, providing consistent and safe refractory insulation. When properly installed, they help maintain regulatory compliance, reduce the risk of heat-related damage, and support safer working conditions.

How does J-3000 mortar contribute to the overall effectiveness of a thermal insulation system?

J-3000 is designed to bond ceramic fiber products and other thermal insulation materials in high-temperature applications. Its strong adhesive properties and thermal resistance provide structural integrity and minimize heat leakage in furnaces, kilns, and power plant systems. When used alongside Nu-Board, J-3000 enhances the overall thermal insulation system by sealing gaps and creating a continuous protective barrier. Additionally, our tadpole gaskets and seals also play a critical role in enhancing thermal insulation systems by sealing off gaps and preventing heat from leaking out at joints, seams, and access points.
