Moisture around attic hatch

[David A. Andersen]

Are these from Lawrence?


DB 74
WB 60
RH 44.0%
DP 50.711


Moisture will condense at 50.7 degrees F.
I think we can find that at an attic hatch in AB.

This looks more like Texas to me.

Caulk around the ceiling hatch trim and around the framing inside the attic hatch.

No, just a reading I got in an award winning architect's building the other day. There was severe condensation on all commercial steel door stiles/sashes.....I'm there working for the owner in litigation against the arch and builder. I think the doors were designed for the warm Gulf Coast of Texas though!!

......I called it at 43% RH.

Thought I'd give you some #'s to start with so you could begin the course.

Yes, it is beyond Home Inspection, but when you start with the IR stuff you need to know it.

Did you obtain any psychrometric measurements of the indoor air I can work with?

David what do you want?

I did not get any Relative Humidity measurements but the inside temp was 20C (68F) and outside 5C (41F)

Another thing they did say is that the windows would freeze up when it was about -20C (-4F). They also just turned down the humidity in the house and have no idea what it was or what it is or when they changed it.

Thanks
