BTU-BLOCK products are a family of microporous insulation designed for use in high temperature industrial applications. Microporous insulation is a very high thermal efficiency material which has a thermal conductivity less than that of still air. These materials, consisting of fine diameter heat resistant particles, reinforcement fibers, and high temperature radiation
blockers, address the primary modes of heat transfer in a novel way compared to traditional refractories.
Standard size is 18” x 24”. BTU-BLOCK Board 1807 is available for on-line ordering in densities of 18 pcf in 1” and 1½” thickness and 20 pcf in ½” and ¾” thickness.

BTU-BLOCK Panel consists of BTU-BLOCK Board encapsulated in a high temperature textile. The exterior fabric maximizes the strength of the panel while providing a lightweight,
low thermal conductivity finished product. The textile also offers mechanical protection, flexural strength and an excellent substrate for bonding the panels to walls or other insulation.
Standard BTU-BLOCK Panel 1208/16 consists of a 1200°F (649°C) rated outer textile, while the core has a continuous use limit of 1800°F (982°C). By substituting a higher temperature
cloth, such as a silica or quartz cloth, the use limit of the entire composite can be increased to 1800°F (982°C).
