Roof radiation shield on a pitched ceiling?

[elnene2k]

I know ICC makes such a thing but have not found any others...Wondering if the ICC one will work on my DuraTech system...

I am supporting the class A pipe on my second floor bedroom then this is where the pitched ceiling is. Any ideas or workarounds?

Bumping. I'm not following your concern. Can you post a shot of the question area or explain?

So, the install will be in the living room corner with a "through ceiling" outlet and in the second floor is our master bedroom. So the class A will meet in the ceiling of the living room/floor of this bedroom. So the support box will be there...

So from here, it will go through the bedroom ceiling which is actually a sloped part of the ceiling that runs parallel to the roof so not much space...I'd like to keep a straight run and not offset it just to be able to go out thought the flat part of the ceiling...I am sure there is a way to do this safely right?



That is why I am thinking of just buying the(broken link removed to http://www.icc-rsf.com/main.php?t=chem_produits&i=11&d=&l=en) and installing it here since Duravent does not make such a thing

Another option I thought of was the Duravent roof radiation shield #9489 but I think I need some sort of shield that goes around the pipe on the bottom of it right?

I've never use that part, but I see no reason why it wouldn't work as long as it doesn't interfere with the roof flashing cone. Will the chimney be chased? If so, this may be unnecessary. Just keep the roof opening large enough so that at all points the wood is 2" from the pipe and the insulation is the same distance away. However, there is no harm that I can see by adding it if you want an extra measure of safety passing through the roof and insulation.

This is straight up above my stove/stove room living area in a bedroom and where the class A runs through the ceiling to the roof. The pros installed it and this is the flashing they put in. If it were in my living area I would make it a little larger for a cleaner look - maybe even trim it out. I think it would also reflect a bit of heat back into the room and even look nice if done well and possibly trimmed out.

I was thinking of a trim piece like that, but it is not flashing in the sense of continuing up through the roof like the ICC piece.

They left it exposed with no chase? I didn't think exposed chimney was permitted in a living space.

I don't see why you can't use a longer support box made for cathedral ceilings, and run that all the way up to the roof. In that case, that is your insulation shield as well as the support box.

How about the Duravent roof radiation shield #9489? Since it will be enclosed/chased, I suspect I can just this instead if the chimney is enclosed? I just thought the sloped ceiling part around the shield I use should be enclosed around the pipe like other setups are that go through a living rooms ceiling...

This is going through a bedroom from the floor below. It must switch to class A at the living room ceiling. The transition can't be in the above bedroom.

That is an insulation shield. Usually this is not installed if the insulation if fiberglass. I think normally this would be used for passing the pipe through foam board insulation, but there is no reason why you can't use it here if further peace of mind is desired. It will need to be scribed and cut to match the roof pitch.
