At Extol we strive to constantly study the latest innovation in the Insulation Industry. Please check back often as we hope to fill this page with great information! If you happen to have an article you’d like posted here, please feel free to contact us.

  1. Extrusion Does Matter – EPS (Expanded Polystyrene) vs XPS (Extruded Polystyrene):  The dependability of an insulation to perform as intended is related to the product’s ability to resist moisture ingress.  Watch this short video to see the difference between an “Expanded” insulation and an “Extruded” insulation: 
  2. Corrosion under insulation is a major concern in the industrial insulation market. Our Extol Feature Design Article this month is the NACE standard practice #SP0198-2010 which provides the current technology and industry practices for mitigating corrosion under thermal insulation and fireproofing materials, a problem termed corrosion under insulation (CUI). Because this corrosion problem has many facets and impacts several technologies, a systems approach has been adopted in this article. This standard is intended for use by corrosion-control personnel and others concerned with corrosion under insulation and/or fireproofing of equipment. It is organized into sections by function and each section was written by specialists in that subject. These specialists are industry representatives from firms producing, specifying, designing, and/or using thermal insulation and fireproofing products on refinery and petrochemical equipment.
