Is it dangerous to leave your house with the dryer running?
Go to your nearest Home Depot or Lowes type storeFind the insulation section talk to an associate about building codesThe latest greatest is the expanded or extruded poly styrene foamsThese come in pink, white, or blue, sheets of different thicknesses.
make sure you get moisture barrier installed first it is a foam bout the thickness of a foam picnic plate it has like a valley it is to keep moisture from building up in your insulation this is most important than any r factor it will work for under the house as well but there you will have to make it lower on one end for the condensation to run out and use chicken wire to do this is costly and expensive and plastic is a no no but some cheep tarp will work well and after it is up cut some slots to let it vent have fun installing the insulation ITCHY but good advice is before you start messing with it get dirty not joking rub dirt all over your body then put on your clothing this will keep the fiberglass from getting under your skinand those masks they are only good for like 5 min so get plenty of them and some cheep swimming goggles .and ear plugs that stuff will mess your ears up baaaaaad .
My tip is to insulate the attic firstSince heat rises, you are losing more of your heat through there than the floorMy house had no insulation when we moved in (I live in Virginia), and we noticed a huge difference just putting a layer of R-19 fiberglass in the atticThe industry standard is actually R-30 for attics, I think, but some is far better than noneBlown insulation is supposed to be cheaper per square foot, but you need to rent a blower to install it.
Is there increased risk? Yes! One of common causes of home fires is from a clothes dryer catching fire, usually from accumlated lintReduce this risk by periodically replacing your exhaust venting for the dryer, and switching from plastic venting to aluminum ventingAnnually removing the shround and vacuuming out accumulated lint will greatly reduce your riskDoing this should allow you to leave your house with greater piece of mind.
