What sealant is used here?

Robert Macy · 2012-01-13T15:44:41+00:00

Where the AC mains romex goes through the hole in the 2x4 across thetop of the studs and on up into the attic, there is some type ofhardened reddish gunk placed around the cabling to plug the hole inthe 2x4 and hold the cable rigidly in place.My guess is that the purpose of the 'gunk' is to hold the cable,prevent critter intrusions, and provide insulation between hollow ofinterior wall and attic.What is that compound?Also, is there a similar, but more pliant, sealant? Just in case thecabling needs to be replaced and the pliant sealant will alloweverything to be pulled out?

Perhaps you should learn more about the building codes in use in other areas of North America before you type out bullshit in a Usenet posting...

It is not "draft stop" because that is entirely for energy codes, Fire Block ? Never heard that term used before as the proper way to refer to the passive fire protection method being discussed here is fire stop...

Your diatribe does not mitigate the fact that "great stuff" foam is not now, has never been NOR will ever be rated as a material allowable for use for fire stop purposes...

Agreed, it was common to use expanding foam for this purpose up until the building code changed a couple of years ago, now it is required to use the rated and approved means of fire stopping in all of those situations... Unless your jurisdiction is still using and applying an older version of the code in their area...

Sorry, but your jurisdiction is apparently using an older version of code -- it is a requirement in most places which have adopted the latest building codes and could potentially be a requirement in your area soon as the code is disseminated from the source and trickles down and gets adopted by each enforcement jurisdiction...
