Media Materials- Fiberglass and Cellulose

Read along as we dive into the differences between fiberglass and cellulose media.

In our last blog we focused on measuring media for replacement and ordering. For this segment we will focus in on another important aspect of the ordering process, media material. We get a lot of questions about the differences between media materials and many may not know there are multiple materials used to make evaporative cooling media. Here at ATEC we offer different varieties of both cellulose and fiberglass media products. We offer the top media brands available in the industry, and strive to be your one stop shop for all media needs.

Media Differences:

Let's get down to the big question, what is the difference between the two materials?

What it quite literally "boils" down to is fire, the fiberglass made media is made of fire retardant materials and engineered to comply with fire rating requirements and standards, and is UL 900 certified.

Both the cellulose media products as well as the fiberglass media products are extremely efficient in design but some applications must meet those fire standards. To show the big difference we put both types of media to the test, the fire test! Check out our video for fiberglass and cellulose media fire test:

Due to the nature and make up of the fiberglass media it is generally more expensive than the cellulose media products so if you do not need to meet fire rating requirements cellulose is a great option.
