May Have Learned Something New !!!

[pierre]

I was at a "FIRE STOPPING" seminar this weekend, provided by 3M.

I have been to 2 other seminars by others, and well... I may have learned something the others did not teach. (this is why it does not hurt to go to as many of the seminars as time and money will afford)

In single Family Dwellings, there are only limited locations within the building that may have a rated fire assembly. Between floors (basement-1st floor, 1st floor-2nd floor) is not a rated fire assembly, therefore not requiring FIRE STOPPING. It will require FIRE BLOCKING, which is less costly and there are many diiferent methods permitted.

Re: May Have Learned Something New !!!

Do you mean "draft stopping" (between floors)? or is that another concept entirely?

Pierre,

Here is part of the IRC reequirement:

R602.8 Fireblocking required. Fireblocking shall be provided to cut off all concealed draft openings (both vertical and horizontal) and to form an effective fire barrier between stories, and between a top story and the roof space. Fireblocking shall be provided in wood-frame construction in the following locations.

As a building inspector I check for this in every house.

We have been told in the recent past, that Fire Stopping was required. All that is required is fireblocking. That means the contractor has many more alternatives, and it will be less costly.


Dave
can you do me a favor and post the rest of 602.8?
