Flame Spread Ratings for Decks

Key Characteristics for decking projects vary from person to person and from project to project.  One of  the criteria we have been hearing more about is flame spread ratings and fire class.

This link provides a great overview of the topic and how it applies to commonly used decking projects:

Of note, you can see most wood products are class III or C which means they are the most flammable.  The exception to this for deck use is Western Red Cedar.

Additionally, most composites are Class B rated, but the only one that I have seen that is Class A is Premium Composites.  This seems to be a unique feature to this product which makes it a consideration in fire prone areas or potentially on roof top applications.

I’m interested to see what other products are used out there in fire sensitive settings.  Let me know.
