There was an old painter there had emphasyma (spelling) and conitnued to smoke and paint without a mask.
I can tell you a regular painters respirator was not great. It should have been a self contained mask & air tank.
I would pull that hood off and respirator off and have a mouth for of grit, along with the inside of the mask being caked. I didn't care much then, I was young and a lil dumber than I am nowawdays. I smoke alot, and years of breathing roofing chemicals, tar etc, has me thinking more these days. But yes, I still don't wear anything cept maybe some glasses when sawing wood etc. But I try and work smart most of the time, cut in ventilated areas etc.. Anyone can bust my stones as much as you feel like it. I know I am high risk due to my past work. And when I think of it, I try not to contribute to it. Everyone is all gung ho for personal safety protection when cutting logs & etc. I see no difference here.

Just throw up the link...... http://www.mcmaster.com/pyrazole said:I'm also working on hearth rebuild issues....did some research and found a ceramic product on McMaster (it's all java, I don't know how to link it). Take a look and feedback.

This alumina silica ceramic fiber is ideal for both high- and low-temperature applications. If exposed to oil or water, it isn't permanently affected—its thermal and physical properties restore after drying.

Certainly pricier than durock, but the size is enough to do a couplefew layers on a typical size hearth....low K's, for sure. Are the K's listed for 1"? or for the respective thickness? I don't know If they are, you're getting R of 1.40 for the 1/16 and 1/8 (@800F!) and R=1.75 for the 1/4". If it's per inch ratings, they're not good at all (R's of .08 on the 1/16, .16 on the 1/8, .43 on the 1/4) . The problems I see: they don't say specifically that it's fireproof, but alumina-silica should be unless they use an organic binder or something...2300F is a lot to ask for anything organic so I doubt it. It's also hard to say how compressible it is...spacers or high hats would fix that, though.

Just looked it up - their Submittal sheet #F102 for it on the
FibeRock web page says it shouldn't be exposed to sustained temps over 125*F so I would say it is NOT suitable.
Durock Cement board IS specifically listed for the application however.
