An electric blanket is not actually electrical in the sense that it has electricity running through the fibers of the material, it is simply a circuit made up of insulated wires and resistance-type, small heaters sewn between two pieces of material As long as the insulation on the wires and heaters do not became damaged the electric current will stay contained inside the circuitIf the insulation did get damaged and the blanket got wet enough to pass that current to your body you very well could get shockedProbably not badly though, unless you had a part of your body touching a piece of metal which is grounded.
I have never seen this doneI have seen batted insulation over celluloseI think the biggest concern is fire hazardCellulose is paperAttics build up heat and wires are exposedManufacturers of bagged cellulose treat the stuff with fire retardant additives but some brands tested proved unsafeIf I was to purchase any cellulose insulation I would want to do fire retardant tests first before it goes in my atticIf you plan on having any blown-in cellulose added to your attic, contact a contractor who specializes in this line of workAt this time I can't give you a yes to something that may harm you or your family.
Yes without a problemThe only thing you have to make sure of is that your attic stays ventilatedThere are trays that fit into the eave to allow air to come up through the eave and vent through the roof top ventsWithout this air flow the attic can become really hot in the summer and lead to water freezing on the roof and leaking in the winter in the north countryBy blowing cellulose insulation over the rolled insulation you will be sealing any damage caused by people or verminThe insulation values or K values are nearly the sameOnly remove the rolled if it is extremely compromised and then only do spot removal.
Yes you can but I would not add blown insulation on top of rolled insulation, cellulose is heaver then rolled insulationWhy go through the expense of renting a blower to add insulation just add another layer of rolled insulation.
I have to disagree with the first two answersCellulose insulation is made of recycled paper (mostly newsprint) that has been treated with a fire retardant chemicalIt can be blown over almost any type of existing insulationMost home centers will let you use the blowing machine free with the purchase of the insulationBe sure to wear eye and ear protection, and a dust maskR30 is a minimum in most areas and I plan to blow my attic up to about R45 because I live in Texas and we get some really hot summersThe fire retardant properties of reputably manufactured cellulose insulation meet or exceed that of fiberglass.
