Clarifying some Nomenclature Questions

After a field walk with a firestop contractor a few months ago I realized that I need to share some information with you about some common mistakes people make when looking at the firestop nomenclature. This video is just the start, we will have a follow up to it as this series progresses. The video today can be seen here. Please let us know what you think of it or how we can help you on your project here.
