I followed the trail to the site of the penetration kits at EPM wherein the 

sealant is referred to as "Biotherm 100 silicone fireblock sealant."

Since I wanted to use a similar material for other penetrations, I attempted 

to further search the net for the subject sealant. there is no source other 

than EPM, so am not sure of its specifications.

Any clues out there?

   This putty is used in a VERY thin interface between firewall

   and the flange of the fitting. Any fire-retarding material

   (from plumbing and/or electrical supplies section of well

   stocked hardware store) will do.

Fire rated sealants are now very common at your local Lowes Depot as it =

is now required by code for many household construction penetrations.  =

Save yourself some time and money and use one of those.  I'm using an =

Intumescent fire barrier caulk for sealing penetrations which actually =

expands and regenerates the barrier as it is hit by flame and crumbles.  =

Very tough stuff, stays flexible, and rated for 4 hour contact.

Michael ...

Where did you get your intumescent fire barrier caulk and is there a part 

number?

Thanks ...

I have some of their kits but have not installed them yet. So I went out to

look at the tubes of sealant. Unfortunately they are blank white tubes. In

searching with Google I found this in the Aeroelectric archives in a message

from David Carter on Dec 4th, 2003:



"Wonderful product (epm.av's) that mimicks Bob's home grown grab bar

solution

and adds the 2000 degree "Biotherm 100 silicone fireblock sealant" to dress

the end of "fire sleeve stuffed sleeve of fire sleeve".



I just called and they buy the VERY expensive sealant and repackage into 1.5

oz doses to sell with the kits." 

Me, I would just use RTV - I have turned a blowtorch on it for minutes and

seen no effect.

Home depot in the caulk section.  Specifically it is 3M Fire Barrier =

Sealant CP25WB.  Anything that is rated for through penetration void =

sealing in construction should be fine but the Intumescent is generally =

considered the best.



  Hope this helps.

Sorry I don't read French and too lazy to use Babelfish.  But I do 

enjoy looking at pictures and if I am understanding your pic's correctly it 

looks as though you are using industrial type electrical connectors for the 

penetration and just sealing with high temp 3m and a fire sleeve. Which I 

don't see why it would not work. Even if the connectors are just galvanized 

steel and not stainless.

Randy,
	




My web page is divided into 4 parts :



- Roles of the firewall

- What's NOT to be done (IMHO) : rubber grommet, putty patch...

- What I did : home made STAINLESS steel penetrations

- What others do : brass fittings, Bob's method, grommet shields, EPM.AV 

Corp' fittings



You may really wish to use Google translator, after all )

Could not get Google translator to work on your website, it could 

not find it (: Although Babelfish came through for me the translation leaves 

somewhat to be desired. Nice site though and informative. Thanks for the 

info.
