The Great Fluffening Part 5

When last we left off, there was just a little bit of framing yet to do, starting with finishing off these collar tie-ish pieces.

Which went in pretty smoothly.

Then we just needed a bit of blocking along the top of this wall, which we'll use later to nail some strapping to.

Which was a good way to use up the world's shittiest piece of universal wood.

Honestly it was more knot than wood, so sticking it in a completely nonstructural location like this made a lot of sense.

But with that done, it's time to get to the main event: actually, finally installing insulation.

It's a good thing I have just barely enough clear space in my car hole to fit a 4x8 sheet of this 2-inch polyiso board.

Anyway, it gets cut out and up it goes.

The cut on this one isn't super smooth. I tried a score-and-snap technique but it wasn't great for a 2 inch thick piece of foam. On the next piece I tried cutting it with a hand saw and it resulted in a much cleaner cut, but was pretty slow.

I think using a utility knife to cut from both sides might be the answer, I'll try that on the next sheet. But first, I want to get the tape up on these two panels while the ladders are in a good spot.

Is it strictly necessary? Eh, can't hurt.

And it's not especially difficult to install.

Just to sate my curiosity, I grabbed my IR camera and took a snapshot of the roof here.

I really didn't expect to see much of a difference, but somehow even in the dead of winter, at about 10°c outside, the insulation is impressively effective. The underside of the sheathing was upwards of 19°c and the insulation was more around 13-14°c. Of course I don't mind the solar gain in the winter, but come summer this reduction will be very welcome, and I can always stick a heater out here on the chilly days to warm things up now that the heat won't be just directly escaping out through the roof.

Well, now I just need to do the entire rest of the roof. Better get to that.
