Attic: Mostly Insulated

Good News! After a couple weeks of not having any insulation in our attic, we are now mostly insulated. Here’s some pics:

Here’s our insulation strategy, sure to make my insulation specialist friend very uncomfortable…. We started with some R-13 fiberglass batts, which we placed between the 2×4 rafters. Then we used some R-38 fiberglass batts, which we placed perpendicular to the rafters to try and eliminate all the little passageways between the batts. It’s nothing fancy, like a hot roof, but it’s gotta be better than the 3 inches of rock wool and crumpled newspapers we had before

Alert readers will also notice that now there are lights in our attic! I’m really excited about it. In our wee little attic space, I installed 5 new lights! That’s gotta be some sort of code violation that will come back to bite us someday. Our attic space is now the best lit space in the whole house. Wasted effort? Maybe, but it was sure nice to have well-lit space while we were laying the insulation….
Also, you’ll notice that some of the R-38 batts are still all wrapped up. That’s because we haven’t gotten around to fixing this:
Once we fix that chimney, then we’ll lay down the rest of the insulation…

  • It's looking pretty cozy up there to me. How was the itch factor on that project?

  • itch factor=high
    rash factor=high

    All Right, R & M, Great job on tackling the crappy part of remodeling/fix-up. You're doing it just the right way.

  • Thanks, Blayne. Can't wait for you to see it when we're done.

    Quick question: Do you feel a noticeable temperature difference since you've placed the new drywall?

  • Anonymous. Not so much when we put the new drywall up – but we definitely noticed a difference within the few hours after we put the insulation in. The difference in just a few hours was noticeable.

    WHy do you ask? You got a project going on?

  • Reub, Darling Friend,
    This is overdue, I'm afraid, but good work. That is, so long as one of the batts you used was kraft-faced and the other unfaced. Otherwise, you'll have a duplicate vapor barrier, which could lead to trapped moisture -> mold. But if you can get the batts in, more power to ya.

  • I'm itching just thinking about that project. Did you address any attic bypasses? That hole in your chimney will be a big one.

    I love your house posts, Reuben. It's so fun to watch things come together, especially since I didn't have to crawl around an attic to get that sense of satisfaction. You are both so handy!

  • About filling in the chimney with foam: that will be a great way to seal up that attic bypass, but the foam insulation can burn, and shouldn't come anywhere near the vent for the furnace and water heater.

    You need to figure out why the chimney is falling apart – it's probably because of a bad or missing crown, or missing mortar at the exterior.

    A high quality, professional repair for the chimney would require a masonry contractor to fill in the missing bricks and re-tuckpoint, or possibly re-build your chimney. The cause of the problem needs to be addressed.

    Another option, which might be less costly, would be to tear down the chimney below the roof line. The chimney is only acting as a chaseway for the furnace and water heater vent – you really don't need it projecting up above the roof any more. I'm not saying this would be easy, but it might be easier than having the chimney professionally rebuilt. You also wouldn't have to do any more work on the chimney.

    You would still need a professional contractor to repair the hole that will be left in your roof. Feel free to call me about this if you want more input.

    Don't foam the chimney.
