There are sound transmission limitations for new construction. It can get pretty sticky. If it is a newly constructed condo (original buyer) then it may be a concern as an inspector, but if it is a resale, I would think it'd be best left alone as Mike O suggest.

S-trapless.

Roofers smoking too much again.

My research last year agrees with what Kurt and Jim have stated.

Well, its dopey alright.

I agree, it also looks like they tracked up the valley while doing it.

No solid information here, but I have seen a lot of pole barns with double-bouble insulation applied to the purlins before the roof metal is put on. The insulation would reduce the condensation, and any drips would run to the end of the roof so long as the insulation is lapped properly. Commercial steel buildings use vinyl backed batts.

Mike, you should refrain from the wd-40. Maybe change over to dry gas.
-
Just what is "wet" gas anyway?
-
Ah, true. To do it all again.....

I agree with the electrician and Richard. I would eliminate the fan motor first if this wasn't a problem until recently. I have found AFCI to be finicky with fan motors more than once.

I would vote for the latter, since turning the clock back would put me carrying them up the ladder.

Radon test. Visually: is it operating, wired properly, vent above roof line, away from windows, securely mounted, etc. I think the specs. may be on the epa link noted above. "Done in a workmanlike manner"

Someone needs to explain that to the manufacturers.
-
The IRC requires 40-80.

Check your appliances for water pressure ratings. Usually they aren't much more than 70 psi for a maximum and about 20 for minimum.
-
www.nrsb.org is another good one.

So, this must be why I feel so bloated after being in one of these places?[?]

Check with your state health dept. They may have a list like NY does.

Why? My biggest question about closed cell has always been, about condensation. How does moisture dissipate? What about the difference between the indoor and outdoor climate? The moisture can't dissipate, but if the cavity is full of closed cell there is no place for the condesation to take place. There is no air to condensate moisture from, or very little anyway.

Sounds like an experiment to me. The manufactures might like to know the outcome of this one.

I have R-21 in 6" walls with R-48 blown overhead, built in 08 and it's been very reasonable to heat. If I want to make changes or modifications later, I don't have to deal with the foam mess. I think if I were going to foam, I would consider going all the way and do the whole house with ICF's instead of conventional framing. Maybe next time.

What Randy said. R-21 batts are not much more costly than R-19. Properly detailed construction will not leak much air, and R-21 would perform as well as the proposed idea, without the concern of a double vapor barrier. Foam is a lot more costly and is probably the reason for the idea posted.(Trying to get the best of both worlds) In my opinion there would be no benefit, but possible trouble. Use one system or the other.
