Johns Manville Reinvents Expert Guide for Insulating LNG Systems

Johns Manville, March 1, 2023

DENVER, Colorado – Johns Manville (JM), a Berkshire Hathaway company and leading industrial insulation manufacturer, announced the release of its new, recently updated systems guide for Trymer® PIR in LNG applications.

The revamped guide is now more user-friendly for both contractors and specifiers. Johns Manville knew the importance of improving this expert LNG guide, so the company worked with a consultant for a professional redesign and redraft. This guide is now a complete reference on insulating a cryogenic or LNG system with detailed illustrations. The guide includes:

  • Comprehensive content on insulating an LNG or cryogenic application
  • Redesigned, easy-to-follow graphics
  • Updated charts and tables
  • Extensive information on the install process

“We are so pleased with the revamped Trymer PIR LNG Systems Guide. This is now the most detailed and complete LNG reference guide in the market,” said Elizabeth Sheehan, Associate Product Manager for JM. “Rather than be a simple step-by-step installation guide, we worked with industry experts to create a reference guide that discusses the use of multiple products, not just those manufactured by JM, in order to reach larger audiences.”

“The guide contains more complete information pertaining to LNG insulation installation processes,” said Heather Sharif, Senior Technical Specialist for JM, “including redesigned graphics, updated ASTM requirements and additional sections that were not previously included.”
