|This is the expanding foam tape (a leftover piece) - the right side is about 1 1/2 inches top to bottom at the full expansion.|

As mentioned earlier in this post, we'll be spray-foaming on Wednesday and as part of that process we'll be conducting our first blower-door test to find any leaks. The spray foam will be applied to the underside of the entire roof as well as all the soffits and gable end walls. We'll also apply the foam to any panel seams and exposed concrete (only at those inside corners where the width of the house narrows). We've already sealed the outside of the gable end walls and soffits with house-wrap, glue, and tape (a mix of Zip roofing tape, house-wrap tape, and window flashing tape). There are still a few panel joints that need sealing on the outside which we'll do on Monday or Tuesday since we're low on the required caulk for that.
