Immediate difference
Mostly I was concerned with how the blower would perform and it exceeded expectations. Sprayed 18 bags in under 2 hours. Also the air didn't turn on till 4 in the afternoon the first day and maintained 69 degrees with ease. It's early, but very pleased thus far!

    Cellulose Insulation
    Blow in material for additional attic insulation. Pricy solution if you need 30 pacs!

    Easy to install, really dusty
    We blew-in 99 bags with our 24-hour rental--putting 1 bag into the hopper every 4-5 min with 3 people. Only fill to the grate because it needs the air to fluff up. Remove plastic as you fill, but stop every 25 bags to get plastic off the mixer paddles.

      Prep in advance and install in little time
      The installation went very smoothly. I took us less than 3 hours to blow-in 30 bags. I repositioned within the attic between each bag was being fed while my ground support was opening the next bag. Start from the furthest corner from where the hose enters the attic and work towards where the hose enters the attic. I believe we were well prepared ahead of time (before the actual installation started): .. sealed the scuttle-hole with a 6mil plastic wall around it .. snaked the 50 foot hose through a soffit to make sure we could reach everywhere. NOTE: THE HD WEBSITE SAYS TWO 50' HOSES, BUT THE NORTH KINGSTOWN STORE ONLY HAS ONE. .. Protected the machine from rain and weather .. Wore ski-mask like safety goggles and a respirator mask: enabled me to breathe easily and see well. Also wore an LED headlamp. .. communicated to my guy on the ground who was feeding the machine with wireless headphones over our cell phones (START/STOP) The machine is not light. Two strong guys can get it into the back of a pick-up truck. Wish we were a little stronger, but got it up there!

      Mine arrived smelling like diesel fuel, and still smell almost a month later.
      While this is likely a good product, mine arrived smelling strongly of diesel fuel. At some point in their production, storage, or transportation I think they must have been exposed to a fine mist that was deeply absorbed into the fibers. I had hoped the smell would eventually dissipate, but it is now nearly a month later and they still stink despite having been kept in a well ventilated area. I am definitely not going to blow this stuff into my walls and then have my place smell like a gas station forever more, so I am stuck with this huge pile of (so far) useless bails.

      yes it works
      I have a new construction house the building inspector told us we needed measuring ruler’s every 300 feet. Did anyone ever hear of this before?

        Worked really well and the house is warmer than with loose cellulose and less space used. The complaints about smell are because their attic was not sealed from the interior of the house when they sprayed it in. A well sealed house prevents drafts and lost heat will have little or no smell from the Bo rite. Once it lays laid undisturbed, the smell will diminish over time.

        Bag material and other objects in insulation.
        This insulation has all kinds of plastic and rope like objects in it. I blew around 450 bags of this stuff. It blows great and seperates great. However it would clog our blower machine up due to the plastic and other objects that would wind up around the finger seperators in our machine. Looks like bag material that when a bag may burst at the factory when filling the bags that it is just scooped up and thrown back into their bag packer with the broken bag included. I do like the price and would buy again. However the factory that bags this stuff needs a better way of rebaging the broken bags.

        I am glad to have the insulation installed in my attic. It seems to be having an effect on my home's comfort level. However, I have an issue with the process of this installation. It was difficult to transport the bails of insulation to my home because there were no rental trucks available at the time I needed one. There was no way to reserve the blower machine because it was already out. I had to reserve it at 3:00 A.M. on a Sunday morning to ensure one was available to me. i was charged for the rental of the machine even though I purchased 58 bails and the clerk entered the wrong reimbursement. I have been told this would be corrected and show up on my account in three working days. after seven days I still did not see the reimbursement and my statement, though past the closing date, was not fully accessible to me and I could not see the correction.
