TR® Block Insulation
Product Information
TR-19 and TR-19HS Block are asbestos-free insulation
products, manufactured from vermiculite granules and hightemperature bonding materials. TR-20 Block is made from
diatomaceous silica with a hydraulic binder. These items are
versatile products available in a range of sizes and thicknesses up to 7” with either beveled or straight edges. Their
unique composition and hard surface helps ensure strong
adhesion of cement finishes, and provides superior handling
qualities.
Because of its low conductivity, TR-19 Block is an economical, energy saving insulation. It exhibits minimal shrinkage at
its 1900°F (1040°C) temperature limit, and will not readily
decompose even when exposed directly to flame or cryolite
vapor conditions.
Features
TR-19, TR-19HS, and TR-20 Block Insulation
• Low thermal conductivity
• Block construction 36" x 12"
• Good high temperature strength
• Variety of thicknesses up to 7”
• Resistant to cryolite vapors
TR-19, TR-19HS, and TR-20 Curved Block Insulation
• Designed for curved or circular equipment
• TR-19 recommended for temperatures up to 1900°F
• TR-20 recommended for temperatures up to 2000°F
Applications
TR-19, TR-19HS, and TR-20 Block Insulation
• Side and end wall insulating material in carbon baking pits
• Backup insulation in aluminum pot cells, reheat and pusher furnaces, copper reverberatory furnaces, and oil-fired
water tube boilers
TR-19, TR-19HS, and TR-20 Curved Block Insulation
• Interior and exterior use on bustle pipes, hot air pipes,
stacks and other curved or circular equipment
TR-19HS Block is a high strength structural insulation material, suitable particularly where mechanical loads are present. This block product has very low shrinkage to its 1900°F
(1040°C) operating temperature limit and is resistant to cryolite vapor conditions.
TR-20 Block is a superior, high-temperature insulation for
service to 2000°F (1095°C). According to ASTM testing procedures, TR-20 exhibits extremely high resistance to breakage to 2000°F (1095°C). Long, maintenance-free service
and maximum operating efficiency is assured by TR-20’s
unique combination of low conductivity and high stability.
TR-20 is also very low in sulfur and iron, making it highly
resistant to attack from atmospheric conditions and greatly
reducing the possibility of product contamination.
These products can be manufactured in special shapes to fit
customer specifications, saving money on both installation
and energy costs.
TR-19, TR-19 HS, and TR-20 Curved Block Insulation is
designed primarily for interior and exterior use on bustle
pipes, hot air pipes, stacks and other curved or circular
equipment. Using properly fitted curved block insulation in
these areas cuts energy costs by conserving resources. The
use of TR-19, TR-19HS or TR-20 for curved surface insulation depends upon the specific application. TR-19 and TR19HS are recommended for temperatures up to 1900°F
(1040°C) where low conductivity or strength is a key requirement. TR-20 similarly combines low conductivity with good
stability for temperatures up to 2000°F (1095°C).
TR Curved Block insulation are available in standard 6" or
12" widths. Special sizes of blocks curved to a specific radius
can also be manufactured.
