   "What is BIB?"Blown in Bat System.It uses chopped dense packed fiberglass that that I think that is much different from the FG used in bat insulation.It is installed simialary to cels.Mixed with an adhesvie and blown in the the stub bay. Or netting is installed and it is blown through a hole in the netting..

   Thank you for the welcome and responses! We've also heard BIB to stand for Blown in Blanket System.

   Happy Saturday!

   Welcome to breaktime. Fill in your profile and you'll get better help. The area you live can make a big difference sometimes.

   Between those two I would recommend cellulose simply because FG uses formaldehyde in the manufacturing process as a binder.

   The best insulation is foam. Check the history here. Of course I sell it so don't believe me. Check http://www.Icynene.com , http://www.Corbond.com .

   Don't believe everything you read either. The BIB ad says they have the highest R value available. Check Corbond brand spray foam, about R7 per inch! Thats right R21 in a 2x4 wall!

   On the other hand, R value is not everything. You'll be much better off with a tight leak proof house with no draft and a real R 10 in the wall than a leaky house with an advertized R15.

   We've used both and I like the BIB system better because it goes in dry and stays dry. The cellulose we used was damp spray and we had to let the house dry out before hanging drywall. Later on we had a trim nail hit a plumbing line and a small amount of water got into the walls and it took an inordinantly long time for the cellulose to dry out. Water being the enemy of homes I like the rapid drying of fiberglass. Celulose does tighten up a house better than fiberglass nad has better sound suppression.

   Spray foam is my favorite, we use Sealection 500 here in NC on the walls and underside of the roof deck. Not the greatest R-value (R-23 in the roof doesn't even meet code) but it allows me to do un-vented roofs and to nail my roof sheathing to my ridge beam (which I like in a hurricane zone). No soffit vents (all our homes have exposed rafter tails so we have a lot of time venting between the rafters that we don't ahve to do any more) Great summer time reduction in roof related heat gain. And our energy star certifier is rating out homes at 60% better than code so the home owners are loving it. Building inspector is another story, they don't like the R-23 rating, but I just get a pre-construction HERS rating from my energy star certifier and include it with my permit package.

   You can get much better foam than the low-density urethane we are using but this gets the job done for us at a reasonable cost trade off.

   Thanks to everyone for the helpful feedback. I will fill in the profile, but we live in coastal Maine if that helps. We were considering using Corbond but it is out of our budget - though we'll probably use Corbond for the ceiling.

   Bumb to piffin. He is in your neighborhood.And I think that he uses BIBS when he does not use foam..

   I am on Islesboro. midcoast region.I use Viking for Corbond as my first choice and RH Price to blow in the BIBs. He can do cellulose too, but I prefer The chopped fibreglass. If it ever takes on any moisture, it will let go of it again better than the cellulose. The R-value is about the same for either of those when densepacked. The cellulose is a PIA if you ever have to disturb it but the BIBs FG is like cotton to toch and it has fewer fine fibre floating around to breathe than the cellulose. I think the BIBs is a penny or two more per foot than cells.I have done a lot of remodeling on houses that had previously been insulated with cellulose so I am prejudiced against it for that reason.Also have seen it hold moisture and support rot tho there are arguments that this is not the fault of the cellulose.I have seen cellulose burn three separate times. It is newspaper ground up so it must be treated against fire spread but I don't have that much confidence in the treatment - tho to be fair, all three were with cellulose installed in the seventies. It could be that treatment has improved since then. Mike Smith here is the Cells afficinado. I like Mike but I still hate cells.If you are having them set up to spray faom in the ceiling, have them do the sills to prevent infiltration too. That is a major part of the benefit of the Corbond system and the few extra feet to do the sills will have a big benefit

   Sealection is no approved for 10 or 10 1/2" in the attic so you can spray an R-38.Way overkill but it is approved.Garett
