Not the place I'm thinking of..... Hardipanel has an "H" channel to hold the panels; it's not flashing necessarily, but it's a channel. Architectural panels like this should have a treated edge intended for exposure, a 1/4 inch (or so) gap, and and (of course) a drainage plane. Dupont had a Tyvek product, black, that was a housewrap intended for use under panels. When you butt the panels, bad things happen, as we can see.

I think I know that dump. Is it down in Logan next to the McDonalds?

Sure it's allowed. It's just really thin and insubstantial. It can work fine. Or not. If you're serious with your copper, it's K or L.

Type M thinwall? Yeah, probably.

It's not about new guys. It's about arrogant proclamations and assumptions. Everyone's a new guy AFAIC. I'm only as good as my last statement. If I walk into someone's scene, I take a few minutes, hours, days, or weeks to get a lay of the land before I open my mouth. This guy walks in and starts lecturing us on HI's, the profession, and what we all don't know. I gave him a relatively mild put down and request for a little respect and he goes to flame with the usual "I've been doing this 25 years and know more than anyone in the room" appeal from authority/statistical syllogism argument. Screw that. He was interpreting my existential cry into the wilderness of asbestos commentary as one of me not knowing what to tell folks. I know very well what to tell folks and it doesn't correlate with a lot of what I know and believe.

I agree. What we got here is a failure to communicate......

I just locked the guy out. He went aflame on me. I shouldn't have called him a dork. I deleted my comment; sorry for being honest. For chrissakes, I remember Kibbel talking about this stuff at least 20+ years ago, and everyone I know in the biz knew about this stuff sometime back in the mid 80's. We have the misfortune of working in a profession where useful and accurate knowledge can be superseded by just about anyone. The whole question of "may contain" or "does contain" gets lost in the general hysteria. Couple that to the secondary, tertiary, 4 layers, 5, 6, 7, and 8 layers of subrogated asbestos litigation, and the whole thing gets pretty squirrely. Drive down the Tri State and every 3rd billboard is some PI attorney advertising for mesothelioma legal services. It doesn't make me want to get very authoritative about asbestos, that's for sure. The EPA even states on their own handout that the information is in flux and they're working on getting it right. So, what are we supposed to tell folks? That's what I was trying to get at with the guy, and he took it as folks in here not knowing anything.

You seem like a well intended fellow, but honestly, you're more than a bit presumptuous in your blanket statements about folks knowledge regarding asbestos. I am supposing your work area, which is approximately midway between almost nowhere and nowhere, keeps you isolated enough that you imagine you know something. And gee whiz, 25 years in asbestos work...that's....umm.....ummmm......yeah, gee whiz..... You're certainly welcome to hang around here and learn something, but I'd find it a bit more enjoyable if you put a lid on your presumptions and have a shred of respect for the collected knowledge of the folks on this board, which is as good as anywhere you're going to find.

An HRV (Heat Recovery Ventilator) might work. I'd be interested in figuring out exactly how the solvent outgassing is "transferring", then effect the transfer. So, an HRV and pressurization might negate the transfer. Unpredictable, though. It's a smell. Getting it 100% is unlikely.

He's in an attic. The heat is causing outgassing of the bitumen and solvents and the stink is penetrating into his apartment. Or something like that. Not sure these are the right descriptions, but I smell this stuff all the time in hot attics. I'm not sure venting, or even power venting, is going to get rid of it.

So, what's your advice? You've outlined the problems, now what do we do about it?

They were the defacto heating system for thousands of Chicago homes. The generic term was "octopus" furnace, for all the ducts scrambled all over the basement. Used to see them all the time. Haven't seen an active on in years.

This stuff is determined by actuarial statisticians, not people with building knowledge. Anything can tilt the situation in ways that are totally screwy. A while back, I was talking with a customer who is a division director (or some such title) with State Farm. He said they use stuff like this to structure growth. Too much biz coming in, don't write galvanized pipe or older roofing. Too little, write anything.

Sure. But if we're being fair, PB got figured out pretty quick by industry time. PEX has been around a long time, and it's not shaking out as bad stuff.

What's not to like?

Look real close. Get a close up pic of vermiculite, then look at this again. The differences are pretty clear.

In fairness, AL has me as one of the highest rated HI's. I get jobs from them. They also pester me relentlessly to pay huge dollars for big ads, which I don't understand at all. Why pay? I just got a little freaked when they posted that review from the condo HOA that never hired me. One thing I've started noticing is a bit of arrogance on the part of AL'ers....they're kind of uppity and a little attitudinal, like "hey, I got the secret info on who's good, don't try your sales pitch on me, and I'm going to tell you how it's going to be because I've got the real info..." sort of thing. I don't like it. I got some scary yelp stories. I wouldn't give them a dime. As soon as you let them in the door, they're like a virus.

Building any marketing campaign around social media, AL, Yelp, or whoever, is dangerous. I've got a review on AL from a guy that isn't even a customer; never did a job for him, talked to him, or anything. They asked me to submit a proposal for a reserve study on a condo building, I sent out my standard proposal form (sent out dozens/hundreds no problems), and the next thing I know there's 3 people in the condo association writing lousy reviews of "my work". I wrote a a very tame response indicating I never worked for them which AL won't publish. Yelp is the worst. It's an extortion racket.

When I do it, it slides out to the max. So, I usually extend it all the way at the start.

Are you sure running is working at keeping it away?

Drift..... I put a small bag of Scott's Turf Builder in my (large) boiler room. The 8" cast iron fittings on the steam risers all developed a thin patina of rust in about 3 days. No condensation, very dry...had to be the turf builder.

I pruned this thread. If someone wants to diss CR, fine with me. If they diss what someone does for a living, it's over the line.

Digression, but interesting observation about heads. We used to have to import Robertson drive fasteners 25 years ago, at ridiculous expense. It's amazing to me that we had to wait 30+ years to get a decent fastener. In the US, they're still only available in some fasteners, not all. Pathetic.

An example of humor being on that fine edge of tragedy and comedy. Humorous, yet chilling....

It's glass. Maybe old 7Up bottles.
