I want to pack the rafter bays of my 1 1/2 story with dense pack cels.
1. No one in my area will do it. Blown in fiberglass or fg batts are my only option. So,
2. Do I need a special blower/hose set up?
3. Should I pack my way to the top while hanging sheetrock. Or just leave a space at the top and do the whole bay at once.
4. Another option I thought of was to finish with foil faced, cut a hole in the top for dense pack. Then strap and sheetrock. Good? Bad? Waste of time?
A cels convert from Iowa, in need of some installation direction…..Thanks

*Thanks Fred....nice picture!!
*So Fred, when you can't seem to find a rental unit that is the "air lock" type, what are you missing out on? Called the big local rental places, none have that style. Will try big insulation suppliers next. What does this machine cost anyways? Maybe I'll just buy one.I remember you mentioned before about adding a plate in the hopper of the regular blower. Is the idea to create a more or less dilute mixture in the hose? In the airlock type, won't the feedwheel keep running when packing, essentially flooding the hose? I ask this thinking you would fill on the way into the space and then pack as you back out.-Rob
*Rob,What the air-lock gets you is the ability to regulate the air/cells mix. You want it really lean so it'll blow in at high velocity and pack well. Taylors rentals has them around here. Maybe they just don't realize what they have is "air-lock" variety. Look for the blast gate at the bottom of the hopper, with the little padle wheel under the blast gate.Steve
*In the custom homes I was working on in Montana the insulation was a blow in type -- netting over the stud cavities and then a white insulation material. The tightly packed walls were then covered with some type of plastic vaper barrier and sheetrocked. Is this what you call "dense-pack cellulose"? If not what do you think it was (is)? Does it work?Your pal,Dan
*Rob - I priced one - new - about $2700.I've heard of used ones under $500.rental places don't have them in my experience - I've only found them at the big box stores like Menards and Home Depot - usually free loaners or very low renatl fee if you buy the cells.(Apologies for not having responded to your email - I still have it on my"desktop" but short on time - just doing a 10-15 minute post by!)Regards. Bill
*I'm not sure the one at Home Depot is right either. It has a 2" hose, can I just reduce it down to 1" to get my velocity up?Another thing - their bags say "Loose Fill Material" on them and look alot chunkier than the stuff that is in my walls. The bag mentions "pressure filling" wall cavities to 2.6 pcf. Is there a particular grade cellulose for dense-packing?-Rob
*We didn't notice it so much in the winter because there's already a bunch of white stuff flying around, but durring the summer I'd be out back hanging siding and all of a sudden it was snowing. Sometimes it would take a little while to register..."Wait a minute, it's summer this week, it shouldn't start snowing again till the END of July..."Glad to be alive period,Dan
*Fredthe local Lowes rents out a cocoon system. it is free for a day when you buy twenty five fifteen pound bags of cells. The hose appears to be a three inch flexible affair.Your opinion ???
*Can I take thier three inch hose and reduce it to a two or inch and half hose to increase velocity??. One application I have in mind is an attic space in a 1200ft residence that never had any insulation to begin with. There is no access to the space so I was hoping to use cells and limit the number of penetrations I had to make into this space. The roof pitch is only a two pitch so I would like to use the hose attached to a two by approach.Thanks Kevin
