Colloquialisms of the Industrial Insulation Industry

Posted by Brittney Fells on Jan 24, 2018 9:27:00 AM

When you work in the industrial insulation industry for several years, you start to notice the number of product names that exist. Some terms you may not be familiar with and others you may hear every day. The difference in terminology can all depend on where you are located or even what part of the world you live.  For example, pipe and tank wrap is called a different name based on your location. In Europe, it goes by Lamella.

Below you will find a list of common products and what they are also known as, created by the GLT Products team.
