Just a suggestion for people to keep in mind when thinking about weather-proofing a home.

I was standing in what is to be the center hall of my once and future house, looking at the exterior wall next to which the main staircase will be built on Thursday. At the same time, one of the subcontractors who was spraying the foam insulation was nearby. When I saw daylight through the exterior wall that had just been sprayed, I called him over and asked him about it and what to do. The light was coming through a space between two framing timbers that was less than 1/8 inch wide, so it was not a big space. The insulation guy suggested that the right answer was either to do nothing or use silicone in between such cracks, which they did on some really "over the top houses" and which made the homes very tight. So, the uninsulated cracks are getting filled with silicone.

DW and I took care of most of the second floor this afternoon.

When he said they did it on "over the top houses", you should have commented, "When I see shotty work like that it usually means I have a sub-par contractor."

Correct, It should never have been there in the first place if they did the job right.

Overall, I'm pleased with most of the work done by most of the subs. In this case, I was talking with a sub spraying insulation. Most of the framing doesn't have visible gaps. Some of it that does is from when it was first built.

Every place I can get to where one framing member meets another, and the insulation has not been sprayed in, that's getting silicone. It's not something I would have thought of before Thursday.

Thanks for the comments on framing.
