" -Okay. Now we're talking with Mark Long and Bob Roundtree."
" -Correct."
" -And this is all about installed fiberglass installation that's blown in but it's not the way we're accustomed to hearing about it, right?"
" -That's right."
" -Okay. Now tell me a little bit about this a process."
" -Well, this it's called Ultra fit. It's made by the Guardian Incorporation and it's a sprayed on application with about a 50-50 mix with water and material. The material has an adhesive additive in it, so that when the water mixes with it,"
" -It adheres to the wall properly."
" -So that's the big advantage, Bob, that's it's not like you're blowing fiberglass wool into cavities in old construction in a remodeling job. It's a new construction were you are spraying it up and you don't have to have the dry wall up yet."
" -Right, the water is there to activate the glue and this gonna hold it in place."
" -Okay. Now this says here, if you get 2 or 3 times more fiber and improved our values, how does that work?"
" -What we've got here is a, when you're spraying with a 2 1/2 pound density were, were gonna receive an R15 and a 2 x 4 wall."
" -Which if you see the batts before, you just can't get that much material in there because of obstructions in the cavity such as wiring, electrical boxes, and so on."
" So that is one of the keys, cause I know that, you know, when were trying to put in batts we're always trying to tape, we're always trying to just kinda juggle it around."
" -Cover it around."
" -And with this kind of application, it covers entirely. What about moisture getting into it?"
" -Fiberglass is glass. It doesn't absorb moisture, Bob. Any moisture to the site to activate the glue is going to evaporate that much faster 'cause that's what's its doing, it's just resting on."
" -And do you have to worry about rodents or insects getting into it?"
" -No, there's no nutritional value from a fiberglass whatsoever."
" -Alright. Well, it looks like there's a lot waste involve in this installation."
" -Well actually Bob, there, it appears to be a lot of waste but it's a totally recyclable product. Everything that has been scrubbed off the wall with the scrubber here, is being vacuumed up and recycle back into the house and be used again."
" -Okay."
" -So you don't mean recycled on another job."
" -No. No."
" -You mean."
" -We gonna use on this job."
" -It's getting vacuumed up as it falls off the wall."
" -That's right. That's right. And we're scrubbing down to the stud facing so the sheet rug will fit nice and smooth."
" -Now up there, I noticed you didn't get any of the cavity between the OSP and the stud, what do you up there?"
" -Well, the reason for that is, we'll actually gonna use a bed up there."
" -So you'll, okay, in areas where the crevice, if you will is smaller than the nozzle itself. You have to use regular old fiberglass padding."
" -That's right, Bob."
" -This is really a new construction kinda application, is it more cost effective than using regular batts?"
" -Definitely more cost effective, a little more expensive, it is an up shelf."
" -You're looking at the other shelf in 1800 square feet between 250 and 300 dollars."
" -One last question. Do you need a moisture barrier?"
" -Yes. We wait 24 hours, Bob and then we come back the next time and put up a full 4 mil poly on top of this and that gives us the vapor barrier which would be the same as the paper on the graph base batt."
" -Sure. And you wait 24 hours to let the water."
" -Right. Right, just a slight amount of water and we let that dry over 24-hour period and it will be gone tomorrow."
" -Thanks Charlie, this is very interesting."
" -Thank you."
