Dense packing exterior sidewalls with cellulose insulation

[SIM]

In order to dense pack with cellulose the fill tube should be inserted up until it reaches the top of the stud cavity. In this example the home was balloon construction and we did not want cellulose to rise and fill the second story sidewall because additional electrical wires needed to be run down from the attic on the second floor. The second floor walls will be dense packed by drilling holes from the inside, as this unit is being remodeled.

What type of insulation blower are you using?

We prefer the Krendl 500 for our crews. Small but packs a lot of power with double blower.

Could you use a longer tube and dense pack the entire wall through the one hole you drilled near the bottom? I guess you'd need a tube at least 16 feet.

Yes, I have done this but it works better when going down from an attic with balloon construction. Gravity helps, or in this case gravity can cause that long 15-20 foot tube to find a place to snag or curl. The weight of the hose will eventually cause a lot of pressure at the bottom. Make sure to use a dense summer hose if you want it to go that far. Good luck!

You can dense pack those walls all the way up, 20 feet or more. See this post here: viewtopic.php?f=1&t=154 about using a long braided vinyl tube for dense packing exterior walls with cellulose.

That 20 foot dense pack tube is a great idea for sidewall insulation blowing but you better have a strong blower. You could never do that with a Intec Force brand machine.
