I got some great comments last week when I posted a short video about mineral wool. So thanks to all the fabulous folks who reached out, I want to share this longer video.

If you think that all mineral wool is the same between brands, check this out and you will learn why they are different and why it is important you don’t use them interchangeably.

This video was part of a firestop training designed specifically for fire sprinkler contractors, but its valuable to anyone who wants to get firestop right.
