DIY Blown-In Insulation: 7 Tips We Learned While Insulating Our Attic 

Thanks so much! It was a big project but so worth it, especially during this crazy winter weather we've been having lately!

Thanks! It's nice for those times when we need access up there (and especially for this particular project!).

I had this in the house we bought. I paid a company to remove it. Can't see my wiring. Can't check for termites. Can crawl around in the roof due to getting it all over you. Can't see the top of walls for adding power outlets.

Thank you!

Thanks! It was a big job but worth the improved energy efficiency.

Thanks! Here’s what Eric said about building the walkway: “The joists run perpendicular to the walkway, so using the hurricane ties was just a clever way to mount the long 2x6’s that support the walkway. There are little 3-4” risers that I had to cut individually at varying heights to keep the platform level as for some reason the joists weren't all the same height. Then I used hurricane ties to connect those to the joists and mending plates to attach the 2x6’s on top of that with a cross beam every 8’ or so, so the joint between OSB would be on top of it. I used weatherproof OSB sheeting I think 1/2 or 3/8, which is designed to be on the outside of the house before sheathing so it shouldn't be susceptible to mold. I then built a dam out of the scraps of OSB and screwed that to the outside to hold the blown in insulation back. I think it was like 6 to 8” tall. I put regular insulation batts (pink rolls) under the walkway before the blown in, so the walkway surface would be all done ahead of time.”

Thanks, Prairie! Yeah, it is nice to have it all done and enjoy the results! The house feels so much warmer.

Thanks! There are some variables (e.g. I think our solar panels have been more productive this summer). But overall our electric bill has been averaging 30% lower year-over-year for the past few months, so the insulation seems to be helping!

Dang! Did you install rafter baffles?
