• Insulation

 

Although CSI does not sell insulation, the insulation is critical to the performance of a bolt-on heating system. There is a large variety of insulation types available on the market. The following information summarizes the most common types used for piping and vessels. (The information is also available in table form through the link at the bottom of the page.) This information is designed to assist in choosing an appropriate insulation type for a given application. The minimum insulation thickness will depend on the specific thermal requirements. Note that the geometry of the bolt-on heating product should also be considered when choosing an insulation type and thickness. Please contact CSI for additional information regarding the most appropriate insulation strategy for a specific bolt-on application.

 

Cellular Glass	Insulation Type: Cellular Glass Other Names: Foam Glass, Cell Glass Construction: Closed Cell Thermal Conductivity @ 300°F: 0.048 (BTU/hr/ft/°F) Temperature Range: -450°F to 800°F Moisture: Does not absorb moisture (impermeable) Crush Resistant: Yes Best Application: Wet environments Price: mid-range Notes: Smells when disturbed and is often avoided for indoor use.
Calcium Silicate	Insulation Type: Calcium Silicate Other Names: Cal Sil Construction: Granular (Open Cell) Thermal Conductivity @ 300°F: 0.041 (BTU/hr/ft/°F) Temperature Range: 80°F to 1,200°F Moisture: Disintegrates when wet Crush Resistant: Yes Best Application: None Price: mid-range Notes: Its only strength is its resistance to crushing.  It is typically used because the insulation specified is outdated.
Expanded Perlite	Insulation Type: Expanded Perlite Other Names: Molded Perlite, Perlite Construction: Granular (Open Cell) Thermal Conductivity @ 300°F: 0.050 (BTU/hr/ft/°F) Temperature Range: 80°F to 1,200°F Moisture: Absorbs moisture but does not wick Crush Resistant: Yes Best Application: High traffic areas Price: mid-range Notes: Typically a good choice when crush resistance is a priority.
Fiberglass	Insulation Type: Fiberglass Other Names: Fibrous Glass, Glass Wool Construction: Fibrous Thermal Conductivity @ 300°F: 0.031 (BTU/hr/ft/°F) Temperature Range: 0°F to 1,000°F Moisture: Absorbs moisture and wicks Crush Resistant: No Best Application: None Price: inexpensive Notes: Same price as mineral wool, but has inferior performance
Mineral Wool	Insulation Type: Mineral Wool Other Names: Rock Wool, Slag Wool Construction: Fibrous Thermal Conductivity @ 300°F: 0.031 (BTU/hr/ft/°F) Temperature Range: 0°F to 1,400°F Moisture: Absorbs moisture but does not wick Crush Resistant: No Best Application: General Use Price: inexpensive Notes: Best performance:cost ratio.  Typically the logical choice for general use.
Aerogel	Insulation Type: Aerogel Other Names: Pyrogel™ Construction: Fibrous Reinforced Aerogel Thermal Conductivity @ 300°F: 0.016 (BTU/hr/ft/°F) Temperature Range: 0°F to 1,200°F Moisture: Does not absorb moisture (impermeable) Crush Resistant: No Best Application: Congested areas or skids where reduced insulation thickness is a priority Price: expensive Notes: New on the market, does not yet have ASTM recognition
