No Burn I Joist Protection

[RJJ]

Anyone out there have experience with NO Burn Plus or other products?

ICC ESR report 1838

 

[cda]

Seen it demoed

Guess it depends on why they are using it and what code section they are trying to achieve

 

[Uncle Bob]

Brings back memories of the Minny Soda meetings; when the fire fighters left just before the vote to require I-joists to be coated for fire protection; and it failed. If it protects the I-joist with a one hour fire rating I'm for it. Uncle Bob

 

[fatboy]

I've heard that TJI has already pulled it from the market, not cost effective.

 

[Builder Bob]

not a fire retardant for fire rating purposes...... used to slow down flame spread and smoke development, not act as an fire barrier(thermal) -

See scope of ICC report - section 2.0

No Burn I Joist Protection

They gave us test data to prove it was a minimum 15 minute barrier

I have a guy here in town that applies it, I have allowed it in limited situations one was on and addition were there where so many penetrations that it was very difficult to meet the fire and smoke barrier requirements, the other was a church lobby were they wanted to keep the high vault and exposed beams.

Jeff: That must be NO Burn Of Northeast!

 

[jar546]

Why?

Just an add on

Or code related??

 

[jar546]

PA has a requirement for TJI's in lieu of the sprinklers in the IRC for 1&2 family. This will be in place of 1/2" sheetrock under the 1st floor.

 

[cda]

Wow , not sure if equivalent ??

 

[jar546]

Actually is equivalent and they have data to prove it. In addition, the applicator is the company that certifies the application taking responsibility and sharing the liability monkey.

The other trade off was 5/8 plywood. I did a burn test as well per the ICC report. It past. 1/2 " dry wall good for at best 20minutes.

5/8 plywood on fire in less than 8 minutes.

when the fire fighters left just before the vote to require I-joists to be coated for fire protection; and it failed

Some.........unfortunately the majority :-(

 

[RJJ]

FM: It seems to be ok. Time will tell. This has gotten tossed into the mix in PA because they took out the requirement for sprinklers. Then cut a deal for 1/2 drywall or 5/8" plywood. Both good for less then 20 minutes. So by the time the fire trucks pull up the floors are just about ready to fail. Anyway you look at it & I Joist home is going to be a trash fire.

I just received this from Weyerhaeuser in regards to their I-joists Weyerhaeuser :: Flak Jacket Fire Protection if you click on the FAQ section they have their ES report linked.

 

[TheCommish]

so when they are installed vertical what doe the movie look like?

 

[jpranch]

Sounds like the jury is still out? New code requirement? Industry will respond. Now I know what might come next but R&D from industry, don't dismiss it. Never discount first to market.

 

[RJJ]

Very Interesting!

 

[kyhowey]

I wonder if you cut a hole in the I-joist, if the edges of the cut hole are to be treated with a fire retardant? Didn't read anything in the ESR report about it.

I am an Engineer with the Trus Joist division of Weyerhaeuser. Regarding "Membrane Protection" of light-weight framing (this would include I-joists, plated trusses, and light weight steel joists), these provisions for single-family structures are listed in section R501.3 of the 2012 IRC. As noted earlier, Pennsylvania adopted nearly identical language in their own code.

Flak Jacket is a Factory Applied protective coating offered by Trus Joist on our TJI joist products. It's available in the markets where this code provision has been adopted.

No Burn is a Field Applied intumescent paint that can be applied to framing members after installation. While some builders may have used this on TJI joists, Weyerhaeuser does not endorse this product.

We have tested and gained approval of the Flak Jacket coating by meeting the requirements of Exception 4 of R501.3. We have followed the ICC-ES AC-14 Acceptance Criteria which requires a loaded assembly fire test using the E119 time-temperature curves. This assembly test has demonstrated that a floor system built with TJI joists with Flak Jacket protection provides equivalent fire endurance to a floor system built with unprotected 2x10 dimension lumber.

Per our evaluation report, web holes that are within the limits of our standard published hole charts are acceptable without further field treatment.
