Tectonite

A unique combination of diatomaceous earth, fiberglass, recycled wood fiber, and other ingredients, Tectonite was first developed and tested internally by Warm Springs Composite Products in 1993.

Since then, Tectonite continues to be tested and certified by at least five different testing agencies in order to expand our U.S. standard fire ratings of 20-90 minutes as well as both the British and European standards for up to 120 minutes.

Tectonite has also been subjected to numerous WDMA testing standards to meet or exceed the "Extra-Heavy Duty" requirements by a number of 3rd party laboratories.
