Calcium Silicate Insulation
When exceptional strength and durability are required along with low thermal conductivity, Johns Manville’s calcium silicate products are the clear answer. Available in a large selection of sizes and forms, calcium silicate can fit many applications.
Calcium Silicate
Thermo-1200 (WATER RESISTANT)
Thermo-1200® is a high temperature, water resistant* Type I calcium silicate designed to inhibit water absorption. In the event of a typical rainstorm water will bead on the surface of the insulation without penetrating into the substrate. This will allow contractors some additional time to install the insulation without immediately applying the jacketing afterward, offering more time and flexibility in the installation process than has traditionally been available. Additionally, Thermo-1200 contains XOX Corrosion Inhibitor®, a proprietary corrosion inhibiting formula that helps inhibit corrosion under insulation (CUI).
Thermo-1200 is available in pipe, block, and curved segments. It is inorganic, non-combustible, asbestos-free, and it meets or exceeds the physical and thermal property requirements of ASTM C533, Type 1. It can be used in systems with operating temperatures that range from ambient up to 1200°F (650°C).

HP BLOCK
HP BLOCK® is a cementitious insulation with exceptional compressive strength (>200 psi/1379kPa), making it ideal for applications where mechanical abuse is likely. The inorganic binder will hold its shape and maintain the physical integrity of the insulation, even past 450°F, the point at which most organic binders burn off. HP BLOCK® is a water-resistant, Type IA calcium silicate block insulation, designed for applications that operate at temperatures up to 1200°F (650°C).
Super CalTemp Gold 1700
Super Caltemp® Gold 1700 block insulation is an inorganic, non-combustible insulation with exceptional strength and extremely low water of hydration. Chemically, Super Caltemp Gold 1700 features a xonotlite crystal structure and is composed primarily of lime, silica and reinforcing fibers. The product is gold in color, essentially dust-free, contains no asbestos and can insulate up to 1700°F (927°C).
Super Firetemp L
Super Firetemp® L is an inorganic, non-combustible, high-temperature insulation for fire protection applications. It can be used in systems operating up to 1800°F (982°C). Super Firetemp L is made primarily of lime, silica and reinforcing fibers. This product is white, essentially dust-free, contains no asbestos, mercury or lead, and meets or exceeds ASTM C656, Type II Grade 5.
Super Firetemp M
Super Firetemp® M is an inorganic, non-combustible, high-temperature insulation for fire protection applications. It can be used in systems operating up to 1800°F (982°C). Super Firetemp M is made primarily of lime, silica, and reinforcing fibers. This product is white, essentially dust-free, contains no asbestos, mercury or lead, and meets or exceeds ASTM C656, Type II Grade 6.
Super Firetemp H
Super Firetemp® H is an inorganic, non-combustible, high-temperature insulation for fire protection applications. It can be used in systems operating up to 1700°F (927°C). Super Firetemp H is made primarily of lime, silica and reinforcing fibers. This product is white, essentially dust-free, contains no asbestos, mercury or lead, and meets or exceeds ASTM C656, Type II, Grade 6.
Super Firetemp X
Super Firetemp® X is an inorganic, non-combustible, high-temperature insulation for fire protection applications. It can be used in systems operating up to 1700°F (927°C). Super Firetemp X is made primarily of lime, silica and reinforcing fibers. This product is white, essentially dust-free, contains no asbestos, mercury or lead.
Super Firetemp S
Super Firetemp® S is an inorganic, non-combustible, high-temperature insulation for fire protection applications. It can be used in systems operating up to 1700°F (927°C). Super Firetemp S is made primarily of lime, silica and reinforcing fibers. This product is white, essentially dust-free, contains no asbestos, mercury or lead.
Super Calstik
Super Calstik® is a modified, silicate-based glue and can be used for bonding and sealing joints in Super Firetemp® high-temperature insulation. It is used in walls, structural steel, cable trays and other fire-rated applications. It sets quickly to provide a high-temperature bond for porous insulating materials and is completely asbestos-free.
