It's good but not a vapor barrier . For vapor barrier effect, you need something with a membrane like foil or plastic to keep the transfer of moisture . . . and the weakening of the insulation properties of ANY insulation from happening . Blow-in ( . google . com/imgres?imgurl=http://www . ki-lumber . com/pics/img . php%3Ftype%3Dspec%26image%3DSpec381 . jpg&imgrefurl=http://www . ki-lumber . com/products . php%3Fformat%3Dspec%26cat%3D279&h=260&w=299&sz=71&hl=en&start=17&tbnid=oTKHLczo3Nc3IM:&tbnh=101&tbnw=116&prev=/images%3Fq%3Dblow%2Bin%2Binsulation%26gbv%3D2%26hl" target="_blank">images . google . com %3Den%26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg . mozilla:en-US:official%26sa%3DG) has approximately the same R-factor as sheet ( . google . com/imgres?imgurl=http://www . smithbros . ie/img/attic . gif&imgrefurl=http://www . smithbros . ie/services_insulation . htm&h=221&w=219&sz=25&hl=en&start=20&tbnid=Qzqnm-yCU7JakM:&tbnh=107&tbnw=106&prev=/images%3Fq%3Droll%2Binsulation%26gbv%3D2%26hl%3Den" target="_blank">images . google . com %26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg . mozilla:en-US:official%26sa%3DG) or roll goods ( . google . com/imgres?imgurl=http://www . engadget . com/media/2006/04/fiberglass-rolls-acoustic . jpg&imgrefurl=http://www . engadget . com/2006/04/04/how-to-theater-or-studio-acoustic-treatments/&h=283&w=424&sz=91&hl=en&start=8&tbnid=37Ps-YK_J9eXIM:&tbnh=84&tbnw=126&prev=/images%3Fq%3Droll%2Binsulation%26gbv%3D2%26hl%3Den" target="_blank">images . google . com %26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg . mozilla:en-US:official%26sa%3DG) . You don't like to get wet when you are in the cold of Winter . That's because water wicks heat out of your body and you can get chilled or frostbite: same with your walls and ceilings . It's the thickness of the batts that form a dead air space actually . Dead air has a really tough time exchanging heat in either direction . . . in or out . The insulation (pink, brown, white, etc) just traps air into dead no-flow zones and there's the insulation factor . Think of a Thermos bottle . The original ones have a vacuum in between the inner and outer glass shell to keep heat from traveling either direction . . in-or-out . They advertised: "Keeps cold things cold; hot things hot . " I worked in cryogenics when I was on the SeaLab project for the US Navy, and we had liquid gasses in giant thermos bottles, if you will, that stood several stories tall . They had no physical insulation . . . just a very good vacuum between the four inch space in the walls . You could put any part of your body on the outer walls and only feel a slight coolness . Just touching liquid nitrogen or argon, for instance, causes instant skin damage . Back to topic: Brown blow-in is usually rock wool . It's not used much any more in the States . The newest product for blow-in is cellulose fibers, treated with acids and stuff and blasted with high pressure air to fluff it up and then it's blown into the attic or floor joists . It is NOT used in walls as then it will sag under it's own weight and leave the upper chambers in the walls above the fireblocks and inside the sheers, empty . The very best insulation is expanding foam . It's expensive; it's also very good . It lends support to the walls and sound deadens them too . It is it's own vapor barrier and requires some installation techniques that are obviously tricky in a built or established residence . It CAN be done . I think there are times when more is better . . but maybe not in your case . The brown-ness of the blow-in usually indicates atmospheric dirt if it's not rock wool . I believe that NZ is also very backwards on insulation and your houses seem to be as drafty as an English castle . . . but that's only because I've seen a lot of complaining of these problems in posts here and before . If you actually DO decide to get your home done, do it the way we do . . . lock the air into dead zones and use a good vapor barrier . Our utility bills are extremely low for as many people that live here with central air conditioning and centralized heat systems, and we expect our homes to be sealed, as warm/cool as we want them to be . The utility companies here will come out and advise or even install insulation or twin-pane glass or further insulate the homes to help the residences and lower their energy usage . Hopefully youse guys have some of the same services . |

| 688808 | 2008-07-14 19:47:00 | Being a builder I can say definitely just throw pink batts on top, you really don't want to breathe to much insulfluff and its thermal rating is crap compared to batts | gary67 (56) | ||
| 688809 | 2008-07-14 22:08:00 | I'm utterly convinced (sorry to hijack the thread) that Surferjoe is Batman. He seems to have done everything, everywhere. It's inhuman. |

Join the club. :D I hope someone spends a lot of time with him, to gain all his knowledge, it would be a horrible loss if he were to pass away, with all that still stored in his head. :dogeye: |

| 688814 | 2008-07-15 00:30:00 | No doubt about it,leave what insulation there is and add batts,you will be as warm as a bug in a rug. 3.2's are best I think. |
