Power

No matter the type of power plant – coal, natural gas, nuclear – Johns Manville Industrial offers the breadth of insulation solutions that are necessary to meet the wide variety application needs that are unique to power plants.

We offer durable, high-temperature insulations, like calcium silicate, that couple high-temperature insulation with resilient compressive-strength and the best corrosion inhibiting performance in the industry. Our product line also includes hydrophobic blankets, mineral wool pipe and block insulations, and a non-combustible fire-protection line. Our insulations help create the safest environments possible while improving process control, addressing CUI, and reducing energy loss and greenhouse gas emissions.

Thin, hydrophobic, microporous blanket (Service Temp: 1200°F)

InsulThin™ HT is a high-temperature, thin, flexible, microporous, blanket insulation. It is made from a highly efficient insulating material that has been used in a variety of industrial and commercial applications for more than 35 years. The thin, extremely low-profile feature of this blanket makes it ideal for applications that require space-saving performance with high thermal-stability. InsulThin HT is hydrophobic and has a very low corrosive potential, helping to prevent corrosion under insulation. Additionally, it can be paired with other Johns Manville Industrial high-temperature insulations, like Thermo-12® Gold or Sproule WR 1200®, to create hybrid systems that capitalize on the strengths of multiple insulations.

Water resistant, type I calcium silicate insulation with XOX Corrosion Inhibitor® (Service Temp: up to 1200°F)

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 still contains XOX Corrosion Inhibitor®, a proprietary corrosion inhibiting formula that helps prevent corrosion under insulation (CUI).

Thermo-1200 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).
