| What are the advantages/disadvantages of both types of attic insulation? Currently I don't use the attic, but if I had to get up there to run electric, etc. would one be better than the other? |

| What insulation? More than one kind can be blown. |

| this will probably start a big discussion... but I don't have a problem with rolls of fiberglass. easy to move if you have stuff to do later in the attic and if fitted into joist bays without stuffing and voids will perform as rated. the advantage with blown is that it settles down in all the joist bays without fitting. later work in attic can be problematic. there is blown fiberglass, white (not itchy), yellow you can also blow foam insulation. we use open cell if not using foam, air sealing between attic and best of luck. |

| Good advice above. If you dont have ducts in the attic, blown cellulose should be cheapest and most effective, especially if you DIY. Big box stores will rent you the blower for free if you buy a certain amount which usually isnt much. |

| I had blown cellulose put in my attic last year. It's made a huge difference in the warmth of the house and in heating bills. The installer left some space for storage. My electrician said they are used to wallowing around in the stuff to work in attics. They can just push it aside and put it back when done. My two cents. |
