Drywall corner clips---attach to drywall.....or not?

There appears to be 2 basic types of clips----those that are just back stops (no attachment to drywall), and those that are (or can be) attached to the drywall.
It seems that if you adhere to the concept of wanting "floating corners" to avoid future drywall corner cracks, that you would want to use the back-stop variety.

Problem with ceilings in house with steel beams

Our house is about 25 years old. Has steel beams. Dirty or discolored lines have appeared on ceilings and also on some walls. LInes are evenly spaced at locations of steel beams. What could be causing this? Contractor says it's not mold or water problem.
I can try to have ceilings professionally cleaned and/or re-painted, but don't want problem to recur.
What can be the cause of this?

Thank you.

Lots of Blower Doors

Thought this crowd might be interested in seeing photos of a test out I completed yesterday with Abe Kruger on a ~20,000 SF Fraternity house at University of Georgia. We used 5 blower doors, interconnected with a PC. Long day, but fun and interesting.

What is the ideal thickness of the dead air space in an insulated glass unit?

I have read that thermal loops get created in the air space of an IG unit which exceed a certain thickness. These cause unwanted heat loss.

Codes run afoul of advice when it comes to insulating my slab

A few months back, I asked about the best way to layer materials for my garage slab on grade with hydronic heating in MN (zone 6):


Consensus was to place 6 mil polyethylene vapor barrier ABOVE XPS insulation, directly beneath concrete slab. PEX tubing would then be stapled to XPS foam boards, and rebar on top of PEX.

Foam Insulation for a Post-and-Beam 1771 Saltbox

I'm restoring a saltbox built in CT in 1771. This house was built using traditional posts and beams, with 1 inch thick oak random width VERTICAL planks for the exterior sheathing. That was topped by clapboard siding. The plank sheathing was installed with no attention to air movement - there are vertical gaps between most planks, but in some areas there are gaps as wide as 6 inches! So I am looking for guidance on the best approach to insulating and siding this house.
