Just had my home energy audit done and the #1 item on the list happens to be a pretty easy one… Get MUCH more insulation in my attic. Currently I’m sitting at 8" of fiberglass which is a big issue. They quoted $1900 to blow in 15" of cellulose in my 1200 sq/ft attic. I’ve seen the blowers in action, this isn’t rocket science and being cheap I’m going to do it myself.
I know Home Depot rents the machine for free when you buy X amount of insulation but I also nothing is “free” and have heard they are grossly overcharging on the insulation.
I did it a bunch of times working for a home builder back in college. It’s not rocket science. Rent the blower, get a pair of walkie talkies and a partner to throw the bales into the hopper, and bring a stick marked off at 15" with you into the attic. Don’t forget to keep the eaves clear.
As for where to get it, aka the point of your thread, I have nothing useful to add. Seems to be my thing today. :io:
why not rip all that fiberglass shit out of there and put in pieces of PolyISO board? its rigid cellulose insulation that is very very easy to get cheaply second-hand from building material recyclers. I did a set of plans for some folks in Amherst about 6months ago where they used this exact method to achieve required R-value using 2x8 roof joists (amherst bldg dept are a bunch of friggen nazis, so this is a huge deal that it was possible)
Because ripping out stuff just to add in other stuff is a pain in the ass. As would getting the old stuff out through my 1.5x1.5 access hole where I would then have to drag it through my house. The pro’s plan was to blow the cellulose in right over the fiberglass so that’s good enough for me.
The existing can’t hurt anything so leave it where it is. Many tool rental shops rent the machine. You can try Kamco downtown. If they have it, let me know and I’ll see what my pricing is, and possibly get it for you. Figure machine and materials and see which deal works the best. Buy the styrofoam baffles from Home Cheapo to keep the eave ventilation open, if you have an eave.
something has to be wrong in this comment…rigid polyisocyanurate is not the same as cellulose…and you have to be careful with the use of exposed foam plastics on the interior of buildings, there have been many a fire involving foam plastics of late that spread crazy fast because that stuff burns.
anyone remember the outside of the casino catching fire in vegas a few years back…all foam insulation on the exterior
ross rental in lockport had one when i was there. piece of shit. cf ross rental (brothers business) on main in clarence may have one. his equipment typically was in nicer shape.
