RTH-USA ILTEX-0.4 Ultralight Fire Insulation Bricks – Box of 6, 9” x 4.5” x 1.25” – High Thermal Insulation, Low Conductivity, Eco-Friendly – Max Service Temp 1562°F (850°C)

ILTEX-0.4 Ultralight Heat-Insulating Brick is a lightweight, high-efficiency refractory solution designed to deliver superior thermal insulation in both industrial and residential applications. Engineered with low thermal conductivity, these bricks significantly reduce heat loss, improve energy efficiency, and help maintain stable high-temperature environments. With a service temperature resistance of up to 850°C (1562°F), ILTEX-0.4 is suitable for a wide range of demanding applications, including boilers, kilns, gas and electric furnaces, heat exchangers, incinerators, fireplaces, and metallurgical equipment. Its ultralight structure makes handling and installation easier compared to traditional dense refractory bricks, while still providing durable performance and excellent protection against heat stress. Manufactured from eco-friendly raw materials, ILTEX-0.4 offers sustainable performance without compromising quality. Whether you’re lining industrial thermal units or upgrading home heating systems, these insulation bricks provide a cost-effective, reliable, and long-lasting solution for achieving safe and efficient refractory construction. Dimensional Tolerances: Length: ± 5/32 in Width: ± 3/32 in Thickness: ± 1/16 in In accordance with ASTM C1261-22.
